Preparations and actions of the first night Through the Christian community in Japan, Pessoa was informed of the intrigues against him and promptly prepared for defense and departure. He prepared a large number of hand grenades and ammunition aboard the ship. Still, due to the large size of the cargo, the ship was not ready to sail until after New Year's Day in 1610, whereas previous Macanese vessels usually returned before Christmas. While the ship was being loaded, Arima tried to entice Pessoa to come ashore with offers of hospitality, saying that he had been sent to Nagasaki only to negotiate silk prices, and that the high officials in Sunpu only wanted Pessoa to give his account of the Macau events in person—he would be pardoned as a foreigner even if he was found guilty. Many Portuguese believed Arima, but not Pessoa, who knew Arima had assembled a force of 1200 samurai against him. Pessoa now would not go ashore even for
mass and ordered his crew to come aboard the carrack to set sail. However, this was delayed as some crew believed that the current crisis was merely Pessoa's feud and dragged their feet, while Japanese guards obstructed most who had wanted to embark. By the time Arima attacked the carrack on January 3, only about 40 Portuguese were on board. Before they struck, Arima, Hasegawa, and Murayama jointly sent a message to the Jesuits justifying their impending attack on the carrack with the fact that Pessoa was trying to escape Japanese justice. They followed with another message suggesting that if the Portuguese crew would give up their captain, the matter would be settled. The Jesuits responded that surrendering their captains was not in Portuguese culture. At night, Arima's armada of junks full of shouting men approached the
Nossa Senhora da Graça unlit and quiet in stark contrast. Some of Pessoa's officers wanted to fire on the mob, being lit by the torches they carried. Still, Pessoa refused to take responsibility for opening hostilities, so the procedures of setting sail and
weighing anchor continued quietly in the darkness. The Japanese shot first, firing two volleys of muskets and arrows, and Pessoa responded with two successive
broadsides of five guns apiece, with flutes and trumpets playing after each volley to add insult to injury. The Japanese flotilla scattered and retreated for the night as the Portuguese carrack anchored off Fukahori (
深堀) for lack of wind. Hasegawa assumed the battle was lost and sent a courier to Sunpu carrying the news. Ieyasu received the news in great rage and ordered all Portuguese in Nagasaki to be executed, including Jesuit missionaries. This order was never carried out, as the courier returned to Nagasaki to find the situation significantly changed.
The second and third days The battle continued with minor variations for the next two nights, with half-hearted parleys carried out in the daytime since the Japanese did not dare to attack during the day. In addition to repeating the first night's manoeuvers, Arima tried various methods to subdue the ship. First, he tried sending two samurai to board the ship in disguise and kill Pessoa on deck, but this failed as the two were not allowed onto the ship. He then sent divers to cut the cables of the ship's anchor, but this was also unsuccessful. On the third night, Arima sent forth a flotilla of
fire ships, but they all drifted off in the wind save one, which slammed into the bow cable of the carrack but was cleared without much difficulty. During the third day, Arima sent a message to Pessoa that he wished to renew negotiations about the silk prices and was willing to send hostages aboard to prove his sincerity, provided that the carrack stayed where it was. Pessoa, in return, demanded the sons of both Arima Harunobu and Murayama Toan and that he be allowed to take the ship to the neighboring anchorage of
Fukuda, where he could wait for favorable winds to go back to Macau. Arima gave no reply, but Hasegawa was furious when he heard about the exchange, telling Pessoa in a message that Arima had no authority to make such a proposal and, on the contrary, had direct orders to kill Pessoa. Hasegawa added that if Pessoa surrendered himself and let the cargo be sold at a price decided by the Japanese, he could intercede on Pessoa's behalf. Pessoa politely declined further negotiations as long as the Japanese continued hostilities.
The final night On the morning of January 6, 1610, a favorable breeze made it possible for Pessoa to move his ship to an inlet near Fukuda, but no further. Seeing that his prey was about to get away, Arima gave chase in a flotilla led by a colossal tower-junk. This junk was built by lashing two large boats together, upon which a wooden
siege tower as tall as the carrack's deck was erected. The tower was covered with wet hides to protect it against Portuguese fire and had openings for the 500 archers and musketeers inside to shoot out of. With the attacking force having swelled to around 3000 samurai due to reinforcements in the prior three days, the flotilla tried to approach the carrack under the cover of the tower-junk. Between 8 and 9 p.m., the flotilla closed in at the carrack's
stern, where only one of the two
chase guns could be used to fend off the attack since the other had been moved to the
prow to protect the ship's cables. A
Japanese Christian captain led the charge, rallying his fellow coreligionists with the reasoning that if the carrack were not destroyed or captured, Ieyasu would turn his wrath onto the Christian community, and the churches would be destroyed. A few Japanese succeeded in boarding the ship but were promptly cut down (Pessoa himself killed two) or were forced to jump into the water. The Portuguese fended off the smaller crafts with hand grenades, but they made little effect on the floating tower, which grappled the
poop deck. Up to this point, the Portuguese casualties had been few, with only four or five Portuguese along with a few
lascars killed, while the Japanese dead were estimated at several hundred. However, six hours into the fighting, a shot from the tower-junk hit a fire pot that a Portuguese soldier was about to throw, smashing it onto the gunpowder at his feet. This started a conflagration that spread through the deck, setting the mizzen sail ablaze. Pessoa and his men retreated to the
forecastle, where they realized they did not have enough men to fight the fire and the Japanese boarders simultaneously. At this point, Pessoa ordered the ship's
magazine to be set on fire since he would rather die than surrender. When the ship's
purser hesitated, Pessoa cast away his sword and shield and picked up a crucifix, and then he exclaimed: "Blessed be thou, oh Lord, since thou willest that all this should end!" He then told his crew to save themselves as he started the fire. The
Nossa Senhora da Graça blew up in two successive explosions, split into two, and sank with cargo, crew, and boarders alike. The Japanese killed all they could see swimming in the water, but a few survivors safely made it onto the shore. André Pessoa's body, however, was never found. ==Aftermath==
