Battle of Imaichi (Chronicles of the Tosando - The Boshin War: Tactical Battalion-Scale Combat) AAR part1

  The Boshin War (戊辰戦争) was a civil war in Japan fought from 1868 to 1869. It marked a major political transformation, after which Japan began its rapid modernization and emerged as a rising global power. This conflict began shortly after the conclusion of the American Civil War and concluded just before the outbreak of the Franco-Prussian War in Europe. After nearly two and a half centuries of relatively peaceful rule under the Tokugawa Shogunate, Japan came under immense pressure from Western powers to open its borders to foreign trade and diplomacy. Observing that several Asian nations had already fallen under European colonial influence, and critical of the shogunate’s ineffective governance, particularly its financial struggles, several powerful western domains mobilized. Most notable among them were Satsuma and Chōshū, which had achieved economic prosperity and undergone partial military modernization. These domains rallied around the Emperor in Kyoto. Although the Emperor had long held largely symbolic authority, these forces sought to restore imperial rule and eliminate the political dominance of the Tokugawa house, even after the shogunate, or Bakufu, formally returned governing authority to the Emperor in 1867. Supporters of the Tokugawa formed alliances to resist these imperial efforts, triggering the outbreak of the Boshin War (戊辰戦争).

 The game "The Boshin War: Tactical Battalion-Scale Combat" (大隊級戊辰戦争) is a spin-off of "The Boshin War 1868 (1868 戊辰戦争)."  While the latter simulates the war at a strategic campaign level, the former focuses on individual tactical battles. The scale of the game is 30 to 60 minutes per turn, approximately 500 meters per hex, and companies or battalions per unit, with each strength point representing 50 to 100 infantrymen. Its scenario book, "Chronicles of the Tosando" (東山道戦記), features eight scenarios covering battles fought in eastern Japan between the Shogunate coalition forces and the New Government army.

 The scenario played this time, "The Second Battle of Imaichi," simulates a clash around the town of Imaichi 今市, located about 100 kilometers north of modern-day Tokyo. After evacuating Edo (now Tokyo), the remnants of the Shogunate forces, led by Otori Keisuke, retreated northeast into the allied Aizu domain to reorganize. Otori then launched an offensive to recapture Imaichi but was repulsed. He tried again by constructing a pontoon bridge over the Otani River, which runs north of the town, to assault Imaichi from the east. This Imaichi scenario begins with an offensive by the Shogunate coalition. However, New Government reinforcements eventually arrive from the east, forcing the former Bakufu forces to retreat north across the river.
