The Tokugawa Shogunate
CHAPTER 19, PART 71870-1880: The Boshin War
By late 1879, the tensions reached a critical point. The last time the southern daimyo had paid their taxes and sent the required envoys to Edo was 1869. It was already a decade of undeclared hostility between the shogun and the southern Tozama Daimyo. Furthermore, Emperor Komei refused to annul his “Expel the barbarians” decree, and the shogunate was faced with increasing complaints from the Westerners of breaches of treaty. In September 1879, an incident in Kyoto would trigger an open confrontation. The Kinmon rebellion, as it would be called, reflected the widespread discontent felt among both pro-imperial and anti-foreigner groups, who rebelled under the Emperor’s edict. Thus, the rebels sought to take direct control of the Emperor to restore the Imperial household to its position of political supremacy. Samurai from the Choshu domain attacked the imperial palace, but were ultimately beaten back and defeated by the shogunate forces in the city. Tokugawa Yoshinobu assembled his forces, calling on the domains to supply forces as well, and proceeded to march south in a punitive expedition against the Choshu. However, the Choshu were not standing alone. In Kyushu, Shikoku and the southern tip of Honshu, the domains of Satsuma, Saga, Tosa and Choshu had assembled a pro-Imperial united front and stood together against Tokugawa’s advancing forces. Tokugawa had the support of the main domains of the north: Kaga, Aizu and Sendai, besides the token assistance provided by smaller loyal daimyo.The shogunate forces had better infantry weapons and drill than the imperial ones, and they had the benefit of having their French advisors march with them. That was true only of the central army of the shogun however, as many of the allied domains sent their troops to battle with antiquated weapons. The imperial forces on the other hand were superior in artillery, fielding many of the modern British Armstrong breech loading guns. The forces met for the first time at the battle of Toba-Fushimi, near Kyoto, which ended in an imperial victory, thanks to their well-used artillery advantage. The shogunate forces, under the field command of French attache Jules Brunet, retreated to Osaka Castle. After what seemed like a devastating blow to the Tokugawa’s army, Emperor Komei declared his support for the restorationist alliance, urging more daimyo to take up arms in the name of Sonno Joi. Tokugawa Yoshinobu was campaigning with his army, and as such no action was taken against the emperor in Kyoto. His call had somewhat of an impact, with a few daimyo in central Honshu switching allegiance to the imperial cause. However, the powerful domains of Kaga and Aizu remained staunchly pro-shogun, and the Tokugawa’s main army was a powerful asset in its own right. Furthermore, the Shogunate controlled the seas, hampering communication and transport between Shikoku, the homeland of the Tosa, and the mainland. In the ensuing siege of Osaka, the imperial forces ended up losing. Being harassed by Shinsengumi units (loyal shogunal gendarmerie) and then having to fight the assortment of the pro-Tokugawa daimyo armies, by the time the core of the imperial forces started engaging the elite Denshutai and Shogitai of the shogun, they were disorganised and severely fatigued. Yoshinobu’s forces, under the direct leadership of Brunet, ended up routing the besieging forces. In anticipation of their retreat, the Aizu used the superior shogunal navy to land their forces behind the frontlines, cutting their retreat towards Choshu. Trapped with enemy forces on both sides, the imperial forces suffered a catastrophic defeat. They attempted to break through the Aizu forces at the battle of Himeji, which was a bloody and brutal encounter which however ended in the further defeat of the imperials. Many of the Satsuma soldiers committed seppuku rather than be captured. The Satsuma leader, Saigo Takamori, managed to escape the encirclement and reach friendly forces later on.
After the disaster at Osaka-Himeji, the prospects of the imperial faction were bleak. Choshu and Tosa lost the bulk of their forces together with their modern equipment acquired over the past decade with so much difficulty. Saga had to abandon most of its artillery pieces, which were now in the shogunate’s hands. Satsuma fared the best, losing only about a quarter of its forces in the campaign and retaining most of its leadership and heavy equipment. Nevertheless, by this point they would be unable to fight Tokugawa’s forces on an equal footing. Before long, the shogunate’s forces attacked and overran the Choshu domain, and their leader, Mori Motonori, was forced to commit seppuku. The Shogunate’s navy, including their newest acquisition, the ironclad Kotetsu built in France, shelled Tosa coastal lands without respite. When offered clemency, the Tosa daimyo, Toyonori Yamauchi, switched allegiances and re-accepted the shogun’s overlordship. Satsuma and Saga were now isolated in central-southern Kyushu against the incoming shogunate onslaught. However, the British did not fail to notice that riding at the top of Tokugawa’s military success was none other than Jules Brunet, officer in the service of His Majesty the King of France.
Not willing to be bested in yet another theatre by the eternal rival, the British Republic ordered its Kagoshima garrison to march out and offer assistance to the Satsuma at once. The Republican Navy’s Japanese Squadron was also deployed, and fought a successful battle against the shogunate navy, forcing it to withdraw with the loss of two gunboats and the Kotetsu seriously damaged. The conflict had escalated. Tokugawa Yoshinobu requested military assistance from France, but it would be months before it could be assembled and deployed to Japan. At the same time, the loans he took from France were reaching their payment deadlines and the shogunate was nowhere near capable of repaying them, as most of the money had been sunk into military and industrial procurements. The prospects were clear: the shogunate would have to default, and the price for that was none other than the port of Yokosuka. Other great powers started showing interest in the developing situation in Japan as well: the Dutch were displeased with the perturbation in trade, and the Russians wanted to guarantee the status quo in order to protect their concessions from the shogunate. There was also the situation in which Britain and Portugal already had exclusive territories on Japanese soil, while the Dutch were actively negotiating to gain the same privileges and the French were about to gain a port through economic pressure. Russia wanted to gain an exclusive treaty port too, and the rest of the Western trading powers demanded generalised negotiations on the situation.
Under the generalised competition created by the situation, France and Britain agreed to de-escalate. The Boshin War had ended with a ceasefire enforced by the Westerners. The subsequent Treaty of Edo (1882) would enshrine the status quo in Japan for the coming decades:
1)The signatory powers shall recognise the Shogun and the Tokugawa administration as the sovereign leaders of Japan. All treaties concerning the Japanese state shall be concluded with the Tokugawa Shogunate.
2) All erstwhile rebel daimyo would return to the de jure sovereignty of the shogun. (However, Britain negotiated for Satsuma to maintain wide autonomy, only owing an annual tribute tax and accepting Tokugawa’s overlordship in international affairs. Satsuma was free to maintain its own military forces (under some restrictions) and administer its own economy. (The backdoor that was the British port of Kagoshima would also prove to be useful in illegal dealings circumventing the treaty). Tokugawa Yoshinobu had to accept the pardoning of the rebel daimyo, and to allow a return to the pre war status quo. No clans were to be demoted or removed from their domains.)
3)The shogunate ceded the specified treaty ports to Western jurisdiction and recognised their sovereignty over them. These concessions would operate under the terms of a 100 year lease. The treaty ports and territories specified were: Kagoshima- to the British Republic; Yokosuka- to the Kingdom of France; Shimoda- to the Russian Empire; Hirado & the Goto Islands- to the Dutch Republic; Tanegashima & Yakushima Islands- to the Portuguese Empire.
4)The port of Nagasaki and all the surrounding lands, including the Nomo and Shimabara peninsulas, and all territory south of the Shiota and Sonogi rivers, shall be ceded to a condominium formed of the signatory parts, who shall promise to establish an international trading settlement, where all current and future signatory parts shall be able to establish trade missions for the purpose of trading with Japan. Besides the signatories with exclusive treaty ports, Spain, Austria, Denmark-Norway and Sweden would have the right to claim concessions in Nagasaki and/or the neighbouring designated area.
5) Japan shall annul all edicts: prohibiting foreigners from freely entering and/or leaving the country; prohibiting foreign and/or Japanese subjects from freely practicing their religion, whichever that may be; prohibiting foreigners from engaging in any trade with Japan and on Japanese soil.
