In short: In 1945, Japan launched a desperate campaign to seize Chinese airfields and secure vital railways. Despite initial momentum, they were met by a modernized, American-equipped Chinese force. The result was a decisive rout that turned the tide of the war in China's favor during its final months.

By April 1945, the Second Sino-Japanese War had raged for over seven years. Japan, exhausted by years of conflict and fuel shortages, launched the Battle of West Hunan to neutralize the Allied airfield at Zhijiang and secure critical rail corridors. With only one train running between Guangzhou and Wuhan, the Japanese army was largely forced to move on foot, highlighting the severe logistical strain that defined their late-war operations.

The Chinese response was meticulously coordinated. The National Military Council deployed 110,000 troops, including the veteran New 6th Corps airlifted from the Burma front. Supported by 400 aircraft from the Chinese Air Force and the USAAF 14th Air Force, Chinese forces utilized the mountainous terrain of the Xuefeng Mountains to ambush the advancing Japanese. By mid-April, Allied and Chinese commanders agreed on a strategy to strike the Japanese flanks and rear, effectively stalling the enemy advance.

The engagement proved catastrophic for the Japanese. While they initially claimed 27,000 casualties, later reports from the First Demobilization Bureau estimated 15,000 killed and 50,000 wounded. Specific units, such as the 109th Infantry Regiment, were nearly decimated. By 7 June 1945, Japanese forces were pushed back to their starting positions. This victory, bolstered by the arrival of 50,000 tonnes of monthly petroleum via the newly opened Stilwell Road, allowed China to equip 35 divisions and shift the war's momentum decisively.

The battle remains significant as the last of 22 major engagements involving over 100,000 troops. It demonstrated the effectiveness of combined air-ground tactics and the impact of improved supply lines on Chinese military capability. The success at West Hunan, particularly the defense by the 74th Corps, was so pivotal that the Nationalist Government later awarded the Flying Tiger flag to the 51st Division for their role in the campaign.
