In order to forestall the bombing of the homeland by American B-29 bombers from bases at Guilin and Liuzhou in China and to seize the Beiping-Hong Kong railroad, Field Marshal Shunroku Hata, Commander-in-Chief of the Japanese Army China Expeditionary Force launched the Ichi-Go (Number one) offensive with a force of some 620,000 men, which was the largest force ever assembled by Japan for a single campaign. The main thrust was a powerful drive southwards from Hankou by the 11th Army, designed to link up with a push westward by 23rd Army from Guangdong.
