Taiko. Part 83

It will have to be Kanbei, Hideyos.h.i.+ said to himself. He's the only one I can send. He summoned a page and said, "Kuroda Kanbei should be in the outer citadel. Have him and Hachisuka Hikoemon come here."

Hideyos.h.i.+ took the letter out and read it once more. It was not really a letter, but the pledge he had requested from n.o.bunaga. Hideyos.h.i.+ could have easily mobilized sixty thousand soldiers right here in Okayama. However, he had not crossed the border into the enemy province of b.i.t.c.hu, which he had to conquer first if he was to defeat the Mori clan. There remained one obstacle in Hideyos.h.i.+'s path into b.i.t.c.hu that he was determined to remove-bloodlessly, if he could. This obstacle was the main castle of the seven fortresses that formed the enemy line of defense on the borders of the province: Takamatsu Castle.

Kanbei and Hikoemon came into the small room, and Hideyos.h.i.+ immediately felt more at ease.

"His Lords.h.i.+p's pledge has just arrived," Hideyos.h.i.+ began. "I'm afraid I'm going to ask you to go through more hards.h.i.+ps. I'd like you to go to Takamatsu Castle."

"Would you mind if I read the pledge?" Kanbei asked.

Kanbei read it with the same respect he would have shown had he been addressing n.o.bunaga in person.

The pledge was addressed to the commander of Takamatsu Castle, s.h.i.+mizu Muneharu. n.o.bunaga promised that if Muneharu capitulated, he would be rewarded with a domain consisting of the provinces of b.i.t.c.hu and Bingo. He had taken an oath before the G.o.ds, n.o.bunaga continued, and nothing could induce him to go back on his word.

"I'd like you and Hikoemon to go to Takamatsu Castle as soon as possible," he told Kanbei. "I doubt there will be any problems when you meet General Muneharu and talk to him, but if there are, I don't imagine he'll remain unmoved after he sees this seal."

Hideyos.h.i.+ looked optimistic, but the two other men were unable to share his confidence. Did he really believe that s.h.i.+mizu Muneharu would betray his masters, the Mori, just because of this pledge, or did Hideyos.h.i.+ have something else in mind?

The journey from Okayama to Takamatsu Castle took less than a day, and the messengers arrived all the quicker because they were on horseback. Pa.s.sing through their own front lines, they looked up in the direction of the Kibi Mountains at the red setting sun.

From this point on, whoever they encountered would be the enemy. This was not the spring they had left behind in Okayama. The fields and villages were deserted.

A rider galloped from the front line to the palisade around Takamatsu Castle and waited for instructions. Finally, Kanbei and Hikoemon were ushered in through the palisade and led to the castle gate. Takamatsu was a typical example of a castle built on a plain. There were rice paddies and fields on either side of the road leading up to the main gate. The embankments and the outer stone walls stood in the middle of paddies. With each step up the stone stairs, the battlements and sharp, pointed walls of the main citadel loomed ever closer overhead.

Once inside the main citadel, it was clear to the envoys that this was the strongest of the seven fortresses on the border. The area inside the castle was broad, and although more than two thousand soldiers were stationed here, it was quiet. Because of Muneharu's decision to fight, the castle was accommodating an additional three thousand civilian refugees. Muneharu had decided to make his stand against the billowing waves of the eastern army in this one castle.

Kanbei and Hikoemon were shown into an empty room.Without his staff Kanbei limped inside with difficulty.

"Lord Muneharu will be here momentarily," the page said. He seemed to be less than twenty years old, and as he withdrew, his behavior was no different from what it would have been in peacetime.

The general came in, sat down unpretentiously, and said, "I am s.h.i.+mizu Muneharu. I understand that you are envoys from Lord Hideyos.h.i.+. Welcome." He seemed to be about fifty, una.s.suming and plainly dressed. He had no retainers on either side of him, only a page of eleven or twelve kneeling behind him. The man was so lacking in ostentation that if it hadn't been for his sword and the one page, he would have looked like a village headman.

Kanbei, for his part, was extremely courteous with this una.s.suming general. "It's a pleasure to meet you. I am Kuroda Kanbei."

As the two men introduced themselves, Muneharu bowed affably. The envoys rejoiced, thinking that they would have no trouble in winning him over.

"Hikoemon," Kanbei said, "would you please tell General Muneharu the purport of His Lords.h.i.+p's message?" Although it would have been more proper for the senior of the two envoys to make the opening remarks, Kanbei thought that the older and mellower Hikoemon would more efficaciously present the merits of their case.

"Allow me to explain our mission, General. Lord Hideyos.h.i.+ has ordered us to talk to you frankly, and I can do nothing less than that. Lord Hideyos.h.i.+ would like to avoid a pointless battle if it is at all possible. I think you fully understand how things are going in the west. In terms of numbers, we can easily raise one hundred fifty thousand men, while the Mori have only forty-five thousand men, perhaps fifty at the very most. In addition, the Mori's allies-the Uesugi of Echigo, the Takeda of Kai, the warrior-monks of Mount Hiei and the Honganji, and the shogun-have all crumbled. What kind of moral justice can the Mori claim today by fighting and turning the west into scorched earth?

"On the other hand," Hikoemon went on, "Lord n.o.bunaga has won the favor of the Emperor and the love and respect of the people. The nation is finally emerging from the darkness of civil war and is greeting a new dawn. Lord Hideyos.h.i.+ is pained by the thought that you and the many fine men who serve you will die. He wonders if there is not some means to avoid that sacrifice and asks you to reconsider one last time."

Taking out n.o.bunaga's pledge and a letter from Hideyos.h.i.+, Kanbei spoke next. "I will not talk of advantages and disadvantages. Instead, I would like to show you something that demonstrates the intentions of both Lord Hideyos.h.i.+ and Lord n.o.bunaga. They both value good warriors. This, therefore, is a signed pledge promising you the provinces of b.i.t.c.hu and Bingo."

Muneharu bowed respectfully to the doc.u.ment but did not pick it up. He said to Kanbei, "These are quite truly excessive words and this is a doc.u.ment granting me an unmerited reward. I have no idea what to say or what the proper etiquette might be. The stipend that I have received from the Mori clan is no more than seven thousand bushels, and surely I am nothing more than a country samurai approaching old age."

Muneharu said nothing about an agreement. Then there was silence. The two envoys sat in suspense. No matter what they said to him, he would only repeat, warmly and with great respect, "This is more than fair."

Neither all of Hikoemon's experience nor Kanbei's genius seemed to be of any use against this man. As envoys, however, they were determined to break through the wall, and they made their last effort.

"We have really said all that we can say," Kanbei said, "but if you have any particular desires or conditions you would like to add, we will be happy to listen to them and transmit them to Their Lords.h.i.+ps. Please speak frankly."

"You're asking me to be frank?" Muneharu asked, almost as though he were talking to himself. He then looked at the two men. "Well, I wonder if you will listen. My hope is that, having reached the end of my life, I do not stray from the right path. That is my first principle. The Mori clan is neither better nor worse than your master in terms of loyalty to the Emperor. Unworthy as I am, I am a retainer of the Mori clan, and even though I've spent an idle life, I've received a stipend from the Mori for many years. My entire clan has received favors from them, and now, during these times of change, I have been ordered to guard the border. Even if I were aiming to make some small profit, and I accepted Lord Hideyos.h.i.+'s kind offer and became the lord of two provinces, I would not be as happy as I am now. If I turned my back on my lord's clan, what kind of face would I be able to show to the world? At the very least, I would appear to be a complete hypocrite to my family and retainers, and I myself would be breaking every precept I have taught them all along." He laughed. "So, while I appreciate the kindness you've shown, please ask Lord Hideyos.h.i.+ to forget about all this."

Shaking his head as though he were deeply sorry, Kanbei spoke quickly and distinctly, "I'm not going to be able to persuade you. Hikoemon, we should go."

Hikoemon was unhappy that they had failed, but he had feared from the first that that might happen. Both of them had predicted that Muneharu could not be bribed. "The road will be dangerous during the night. Why don't you stay in the castle tonight, and then leave early tomorrow morning?" Muneharu insisted. It was not simply formality on his part, and the envoys knew he was a truly warm human being. He was their enemy, but he was an honest man.

"No, Lord Hideyos.h.i.+ will be waiting anxiously for your reply," Hikoemon said. The envoys asked only for torches and then set out on their way. Concerned that something might happen to them, Muneharu sent three of his retainers to take them as as the front lines.

Kanbei and Hikoemon had ridden all the way to and from Takamatsu Castle without breaking their journey for rest or sleep. As soon as they arrived in Okayama, they went straight to Hideyos.h.i.+. Their report was short and factual: "General Muneharu refuses to capitulate. His resolve is firm, so another attempt at negotiation would be futile."

Hideyos.h.i.+ did not appear to be surprised. He told the two men to come back after they had rested. Later that day, Hideyos.h.i.+ summoned the envoys and several of his generals for a conference.

Referring to a map of the area, Kanbei reviewed the position of the defensive line of seven fortresses. Hideyos.h.i.+ looked up from the map and stretched out as though he were tired. Earlier he had received news of n.o.bunaga's victory in Kai. Comparing the ease of his lord's successes with his own difficulties, Hideyos.h.i.+ hoped that his prospects would improve from then on. He had at once addressed a letter to n.o.bunaga, to express his congratulations and explain the prospects for his own campaign, and to inform him that he had dropped the idea of trying to persuade s.h.i.+mizu Muneharu to surrender.

Around the middle of the Third Month, the twenty thousand troops who had been standing by at Himeji entered Okayama, and the Ukita clan sent another ten thousand men. Thus, with a combined force of thirty thousand, Hideyos.h.i.+ cautiously advanced into b.i.t.c.hu. After marching only one league, he stopped and waited for reconnaissance reports; after another two leagues, he halted to reconnoiter again. Every soldier had heard the reports of the brilliant victories in Kai, so many found this prudent advance frustrating. Some hastily declared that Takamatsu Castie and the other smaller fortresses could be captured in a single swift advance.

When they understood actual battlefield conditions and the enemy's positions, however, they had to admit that winning a quick victory would be difficult.

Hideyos.h.i.+ made his first camp on Mount Ryuo, a high plateau well to the north of Takamatsu Castle. From there he could look directly into the castle itself. At a glance he could see the lay of the land and appreciate the interdependence of the fortresses and main castle. He could also survey troop movements from the Mori clan's headquarters and be forewarned if they sent reinforcements.

Hideyos.h.i.+ began the campaign by taking the small border fortresses one by one, until only Takamatsu remained. Concerned about this negative turn of events, Muneharu sent repeated messages to his overlords, the Mori, begging for reinforcements. One after another, couriers departed with ever more desperate appeals, but conditions did not permit the Mori to counterattack. And it would take them several weeks before they could a.s.semble an army of forty thousand men and march to Takamatsu Castle. The only thing the Mori could do was encourage Muneharu to hold on and a.s.sure him that reinforcements were on their way. Then all communications between the castle and its allies were cut.

On the twenty-seventh day of the Fourth Month, Hideyos.h.i.+ laid siege to Takamatsu Castle. But the fifteen thousand men at his headquarters on Mount Ryuo did not move. Hideyos.h.i.+ positioned five thousand men on the high ground at Hirayama and the ten thousand men of the Ukita clan on Mount Hachiman.

Hideyos.h.i.+'s generals positioned themselves at the rear of the Ukita contingent. It looked like the first arrangement of counters on a go board, and the positioning of his own retainers to the rear of the Ukita, who until recently had been allies of the Mori, was a matter of prudence.

There were skirmishes between the vanguards of the two armies from the first day of the siege. Kuroda Kanbei, who had just returned from inspecting the front lines, went to see Hideyos.h.i.+ and described the first day's b.l.o.o.d.y engagement.

"During this morning's battle," Kanbei began, "Lord Ukita's warriors suffered more than five hundred casualties, while the enemy lost no more than a hundred men. Eighty of the enemy were killed, and twenty others were taken prisoner, but only because they were seriously wounded."

"It was to be expected," Hideyos.h.i.+ said. "This castle will not fall without bloodshed, it seems that the Ukita fought well." The loyalty of the Ukita vanguard had indeed been tested.

With the Fifth Month the weather turned sunny and dry. The Ukita, who had suffered heavy casualties in the initial fighting, dug a trench across the front of the castle walls for five nights under cover of darkness. Once the trench was completed, they launched an attack on the castle.

When the defenders saw that the Ukita had advanced as far as the castle gate and outer walls, they hurled insults at them. It was easy to imagine the anger they felt toward these men who had once been their allies but who were now fighting as Hideyos.h.i.+'s vanguard. As soon as they saw their opportunity, the defenders threw open the main gate and charged out.

"Attack these maggots!" they shouted. "Kill them all!"

Samurai to samurai, soldier to soldier, they grappled and struck at each other. Heads were taken and raised, and they fought with a ferocity rarely seen even on a battlefield. "Fall back! Fall back!" the Ukita general suddenly shouted in the middle of clouds of dust and smoke.

Glaring at the retreating Ukita, the defenders were carried away with the desire to crush them underfoot. They started to pursue them with cries of "Strike them down!" and "All the way to their banners!"

Too late, the mounted commander of the castle vanguard spotted the Ukita trench ahead. Seeing the trap, he tried to stop his men, but they stumbled forward, unable to see danger. A volley of gunfire and thick gunpowder smoke instantly rose from the trench. The attackers staggered and fell.

"It's a trap! Don't fall into the enemy's trap! Lie down! Lie down!" the commander shouted. "Let them fire! Wait for them to reload, then jump on them!"

With fearful war cries, several men sacrificed themselves; they leaped up to draw enemy fire and were bathed in bullets. Judging the interval before the next round, others toward the trench and jumped in, filling the earth with fighting and blood. That night it began to rain. The banners and the curtained enclosures of Mount Ryuo were drenched. Hideyos.h.i.+ took cover in a hut and watched the melancholy clouds of the rainy season. He did not look very cheerful.

He looked around and called to a retainer, "Toranosuke, is that the sound of rain or someone's footsteps? Go see what it is."

Toranosuke went out but quickly returned and reported, "Lord Kanbei has just now returned from the battlefield. On the way back, one of the men carrying his litter slipped on the steep path, and Lord Kanbei took a hard fall. Lord Kanbei just laughed as though he were amused."

Why was Kanbei out at the front lines in this rain? As usual, Hideyos.h.i.+ was impressed with Kanbei's untiring spirit.

Toranosuke withdrew to the next room and put firewood on the hearth. With the rain, the mosquitoes had begun to hatch, and they were especially troublesome that evening. The fire heated up the already muggy atmosphere, but at least it also smoked out the mosquitoes.

"It's smoky in here," Kanbei said, coughing. He limped past the pages and entered Hideyos.h.i.+'s room unannounced.

He and Hideyos.h.i.+ were soon talking happily. Their voices almost seemed to compete with each other.

"I think it's going to be difficult," Hideyos.h.i.+ said.

Hideyos.h.i.+ and Kanbei fell silent for a moment and listened to the dreary sound of the early summer rain pouring off the eaves of the makes.h.i.+ft hut.

"It's just a question of time," Kanbei began. "A second all-out offensive would be a gamble. On the other hand, we could resign ourselves to a long campaign and besiege the castle at our leisure, but there are great dangers in that, too. The forty thousand troops from the Mori's home province might arrive and attack us from the rear, and then we would be caught between them and the men in Takamatsu Castie."

"That's why I'm so depressed this rainy season. Don't you have any good ideas, Kanbei?"

"I've been walking around the front lines for the last two days, looking carefully at the position of the enemy castle and the surrounding geographical features. At this point I have only one plan on which we could stake everything."

"Takamatsu's fall is not just a question of taking a single enemy castle," Hideyos.h.i.+ said. "If it falls, Yos.h.i.+da Castle will soon be ours. But if we stumble here, that one defeat will cost us five years of work. We need a plan, Kanbei. I've asked the people in the next room to withdraw so you can speak without reserve. I want to know what you'n thinking."

"It's rude of me to say so, but I suspect you have a plan too, my lord."

"I won't deny it."

"May I ask what yours is first?"

"Let's both write our ideas down," Hideyos.h.i.+ suggested, bringing out paper, brush, and ink.

When they had finished writing, the two men exchanged sheets of paper. Hideyos.h.i.+ had written one word, "water," and Kanbei had written two: "water attack."

Laughing out loud, the two men crumpled the sheets of paper and put them in their sleeves.

"Man's wisdom obviously doesn't exceed certain limits," Hideyos.h.i.+ said.

"That's true," Kanbei agreed. "Takamatsu Castle stands on a plain conveniently surrounded by mountains. Not only that, but the As.h.i.+mori and seven other rivers run through the plain. It should not be difficult to divert the water of these rivers and flood the castle. It's a bold plan that most generals would not even think of. I can't help but admire how quickly you grasped the situation, my lord. But why do you hesitate to put it into action?"

"Well, since ancient times, there have been plenty of examples of successful attacks on castles using fire, but almost none with water."

"I think I've seen it mentioned in the military chronicles of the Later Han Dynasty and the period of the Three Kingdoms. In one of the chronicles I read something about our own country during the reign of Emperor Tenchi. When the Chinese invaded, our soldiers built dikes to store water. When the Chinese attacked, the j.a.panese soldiers were going to cut through the dikes and wash them all away."

"Yes, but they didn't actually have to put the plan into operation because the Chinese withdrew. If this plan is carried out, I'll be using a strategy that has no precedent. So I'm going to have to order some officials who have detailed knowledge of geography to determine what will be necessary in terms of time, expenses, and men for the engineering work."

What Hideyos.h.i.+ wanted was not just a rough estimate, but concrete figures and a flawless plan.

"Absolutely. One of my retainers is very clever with such things, and if you order him to come here now, I think he'll have a clear answer for you right away. In fact, the strategy I had in mind is based on this man's ideas."

"Who is he?" Hideyos.h.i.+ asked.

"Yos.h.i.+da Rokuro," Kanbei replied.

"Well, call him right away." Then Hideyos.h.i.+ added, "I also have someone at hand who is conversant with construction and land conditions. What would you think about calling him here at the same time and having him talk with Rokuro?"

"That would be good. Who is he?"

"He's not one of my retainers but a samurai from b.i.t.c.hu. He's called Senbara Kyuemon. He's here in camp right now, and I have him working exclusively on making charts of the area."

Hideyos.h.i.+ clapped his hands to summon a page, but all of his personal attendants and pages had withdrawn to some distance, and the sound of his clapping did not reach them. The din of the rain compounded the problem. Hideyos.h.i.+ got up and stepped into next room himself, and yelled out in a voice that would have been more proper on a battlefield, "Hey! Isn't anybody here?"

Once the decision had been taken to proceed with the water attack, the main camp on Mount Ryuo was found to be inconvenient. On the seventh day of the Fifth Month, Hideyos.h.i.+ moved to Mount Is.h.i.+, which had been chosen because it overlooked Takamatsu Castle.

On the following day Hideyos.h.i.+ said, "Let's start to measure the distances."

Hideyos.h.i.+, accompanied by half-a-dozen generals, rode to the west of Takamatsu Castle, to Monzen, on the banks of the As.h.i.+mori River. All the while he kept an eye on the castle to his right. Wiping the sweat from his face, Hideyos.h.i.+ summoned Kyuemon. "What's the distance from the ridge of Mount Is.h.i.+ to Monzen?" he asked.

"Under a league, my lord," Kyuemon answered.

"Lend me your map."

Taking the map from Kyuemon, Hideyos.h.i.+ compared the construction of the proposed dike to the lay of the land. There were mountains on three sides, creating a natural baylike formation, extending in the west from Kibi to the mountainous area of the upper reaches of the As.h.i.+mori River; in the north from Mount Ryuo to the mountains along the border of Okayama; in the east to the edge of Mount Is.h.i.+ and Kawazugahana. Takamatsu Castle was situated right in the middle of this open plain.

In Hideyos.h.i.+'s eyes the fields, rice paddies, riding grounds, and villages on this flat plain were already submerged. The way he saw it, the mountainous banks on three sides could be viewed as a winding line of capes and beaches and Takamatsu Castle itself as a solitary man-made island.

Hideyos.h.i.+ gave the map back to Kyuemon, rea.s.sured about the feasibility of the project, and once again mounted his horse. "Let's go!" he called out to his attendants, then said to Rokuro and Kyuemon, "I'm going to ride from here to Mount Is.h.i.+. Take the measurements for the dike by following the hoofmarks of my horse."

Hideyos.h.i.+ turned his horse due east and galloped off, riding straight from Monzen to Harakozai, and then describing an arc from there to Mount Is.h.i.+. Kyuemon and Rokuro chased behind him, leaving a trail of powdered rice meal. After them followed laborers who drove in stakes to mark the line of the dike.

When the line that had been drawn became an embankment and the waters of the seven rivers were diverted to flow inside it, the entire area would become a huge lake shaped like a half-open lotus leaf. When the men looked carefully at the lay of the land that formed the border between Bizen and b.i.t.c.hu, they realized that it must have been part of the sea in the distant past. The battle had commenced. It was not to be a battle of blood, but a war waged against the earth.

The length of the dike was to be one league; its width was to be thirty feet at the top and sixty feet at the base. The problem was its height, which had to be proportional to the height of the walls of Takamatsu Castle.

In fact, the primary factor a.s.suring the success of the water attack was the fact that the castle's outer stone walls were only twelve feet high. Thus the height of the dike of twenty-four feet was figured from a base of twelve feet. It was calculated that if the water level rose to that height, it would not only submerge the castle's outer stone walls but also flood the castle itself under six feet of water.

It is only rarely, however, that a project is completed ahead of schedule. And the problem that so troubled Kanbei was one of human resources. For the most part, he would have to rely on the local farmers. The population of the neighboring villages, however, was rather spa.r.s.e, because Muneharu had taken more than five hundred farming families into the castle before the siege, and many others had fled to the mountains.

The farmers who had taken refuge in the castle were ready to live or die with their lord. They were good, simple folk who had served Muneharu for years. Many of those who remained in the villages were people of bad character, or opportunists who were willing to work on a battlefield.

Hideyos.h.i.+ could count on the cooperation of Ukita Naoie, and Kanbei was able to muster several thousand men from Okayama. But what troubled him was not getting this number of men together; his problem was how to use those human resources with the greatest efficiency.

On a tour of inspection, he called over Rokuro and asked for a progress report.

"I'm sorry to say that we may not meet His Lords.h.i.+p's schedule," Rokuro replied sadly.

Even the mathematical brain of this man could not figure out how to extract hard rk from the mixed group of laborers and ruffians. For this reason a series of guardhouses had been set up every ninety yards along the dike, and soldiers were stationed at each of these surveillance points to encourage the laborers. Because the soldiers were simply there as pa.s.sive observers, however, the thousands of men who swung their mattocks and shouldered dirt like ants were hardly spurred on at all.
