硝烟下の桃源境 江南の「日の丸部落」

硝烟なほ烟る揚子江附近の片隅に、我が軍の庇護によつて平和に歸つた二つの部落がある。その一つは『日の丸部落』といはれる盛家橋部落で、入り口には『兵は立ち入るを禁ず』といふ派遣部隊長の告示がある。村長さん格におさまつてゐるのは田窪忠司部隊長で、村民たちから先生々々と慕はれている。約四百名の村民は、我が軍の保護によつて敗殘支那兵の掠奪をまぬかれ意を安んして土に親しんでいる桃源境である

Utopia amidst the Gunpowder: The "Rising Sun" Village in Jiangnan.

There are two villages regain peace thanks to protection by our army in a corner near the Yangtze River, where gunpowder still smokes. One is Shengjiaqiao village, known as the 'Rising Sun Village.' There is a notice by the Unit Commander at the entrance: "Off-limits to soldiers." Unit Commander Takubo Chūji, who acts as village mayor, endear himself to villagers. This is a utopia where about 4000 villagers are free from looting by losing Chinese soldiers, break the earth without anxiety.
