Resistance of the Northern Coalition

After Yoshinobu's surrender, most of Japan accepted the emperor's rule, but a core of domains in the North, supporting the Aizu clan, continued the resistance. In May several northern daimyōs formed an Alliance to fight Imperial troops, the coalition of northern domains composed primarily of forces from the domains of Sendai, Yonezawa, Aizu, Shōnai and Nagaoka, with a total of 50,000 troops. An Imperial Prince, Kitashirakawa Yoshihisa had fled north with partisans of the Tokugawa shogunate and was made the nominal head of the Northern Coalition, with the intention of naming him "Emperor Tobu".

In May 1868, the daimyō of Nagaoka inflicted high losses on the Imperial troops in the Battle of Hokuetsu, but his castle ultimately fell on May 19. Imperial troops continued to progress north, defeating the Shinsengumi at the Battle of Bonari Pass, which opened the way for their attack on the castle of Aizuwakamatsu in the Battle of Aizu in October 1868, thus making the position in Sendai untenable.

Enomoto's fleet joined Sendai harbour on August 26. Although the Northern Coalition was numerous, it was poorly equipped, and relied on traditional fighting methods. Modern armament was scarce, and last-minute efforts were made to build cannons made of wood and reinforced with roping, firing stone projectiles. Such cannons, installed on defensive structures, could only fire four or five projectiles before bursting. On the other hand, the daimyō of Nagaoka managed to procure two of the three Gatling guns in Japan and 2,000 modern French rifles from the German weapons dealer Henry Schnell.

The coalition crumbled, and on October 12, 1868 the fleet left Sendai for Hokkaidō, after having acquired two more ships (Oe and Hōō, previously borrowed by Sendai from the Shogunate), and about 1,000 more troops: remaining Shogunate troops under Ōtori Keisuke, Shinsengumi troops under Hijikata Toshizō, the guerilla corps (yugekitai) under Hitomi Katsutarō, as well as several more French Flag of Second French Empire Second French Empire was the 18-year Imperial Bonapartist regime of Napoleon III from 14 January 1852 to 27 October 1870. The Second Empire is given high credit for the rebuilding of Paris with broad boulevards, striking public buildings, and elegant residential districts for upscale Parisians. In international policy, Napoleon III tried to emulate his uncle Napoleon I, engaging in numerous imperial ventures around the world as well as several wars in Europe.French advisers (Fortant, Garde, Marlin, Bouffier).

On October 26, Edo was renamed Tokyo, and the Meiji period officially started. Aizu was besieged starting that month, leading to the mass suicide of the Byakkotai (White Tiger Corps) young warriors. After a protracted month-long battle, Aizu finally admitted defeat on November 6.

Boshin War (1868-1869)

Boshin War sometimes known as the Japanese Revolution, was a civil war in Japan, fought from 1868 to 1869 between forces of the ruling Tokugawa shogunate and those seeking to return political power to the Imperial Court. View Historic Battle »

Early discontent against the Shogunate: In 1854, Commodore Perry opened Japan to global commerce with the implied threat of force, thus initiating a period of rapid development in foreign trade and Westernization. In large part due to the humiliating terms of the Unequal Treaties, as agreements like those conveyed by Perry are called, the Shogunate soon faced internal hostility.

Foreign military assistance: Despite the bombardment of Kagoshima, the Satsuma domain had become closer to the British and was pursuing the modernization of its army and navy with their support.

Coups d'état: Following a coup within Chōshū which returned to power the extremist factions opposed to the Shogunate, the Shogunate announced its intention to lead a Second Chōshū expedition to punish the renegade domain.

Opening conflicts: Shogunate forces attacked the forces of Chōshū and Satsuma, clashing near Toba and Fushimi, at the southern entrance of Kyoto. Some parts of the 15,000-strong Shogunate forces had been trained by French military advisers, but the majority remained medieval samurai forces.

Surrender of Edo: Saigō Takamori led the victorious imperial forces north and east through Japan, winning the Battle of Kōshū-Katsunuma. He eventually surrounded Edo in May 1868, leading to its unconditional defeat after Katsu Kaishū, the Shogun's Army Minister, negotiated the surrender.

Resistance of the Northern Coalition: After Yoshinobu's surrender, most of Japan accepted the emperor's rule, but a core of domains in the North, supporting the Aizu clan, continued the resistance.

Hokkaidō campaign: Following defeat on Honshū, Enomoto Takeaki fled to Hokkaidō with the remnants of the navy and his handful of French advisers.

Aftermath: Following victory, the new government proceeded with unifying the country under a single, legitimate and powerful rule by the imperial court. The emperor's residence was effectively transferred from Kyoto to Edo at the end of 1868, and the city renamed to Tokyo.
