Stilwell gave the Chinese 22nd Division orders to advance against the bridges held by the Japanese on March 15. After two months of fighting, Myitkyina was now in reach. With the arrival of the rainy season, the incessant rain did not stop until May 17. On that day, at 10:00 p.m., the Chinese Expeditionary Force launched an attack with the US Army's Merrill's Marauders against the Japanese
airstrip at Myitkyina, supported by artillery. Eight Japanese planes were quickly destroyed as the battle escalated. The Japanese were caught by surprise, and, not knowing where their enemies were, poured gasoline onto the airfield in an attempt to disable it and retreated into Myitkyina proper, intending to fight the Chinese and Americans on more favorable terms there. The Chinese and the Americans quickly overran the field relatively intact, whereupon U.S. Army Air Forces and Royal Air Force
C-47 Skytrain transport aircraft moved the Chinese 89th Regiment of the 30th Division to the battlefield to supplement the exhausted CEF and Marauder units already at Myitkyina. A stalemate ensued throughout June, but the
capture of Mogaung by the British
Chindits under
Mike Calvert later that month was the beginning of the end for the Japanese garrison at Myitkyina. With supply lines cut, infighting grew between the two local Japanese commanders over their orders regarding the defence of the town. Stillwell had demanded that the Chindits join them but they were whittled down by disease and combat. Stillwell nevertheless was reinforced by the arrival of elements of
Francis Festing's
36th Division from 15 July at Myitkyina airfield. On hearing of the weakening Japanese garrison in Myitkyina, Stillwell sent that division not to take Myitkyina but to advance on the 'Railway Corridor' from
Mogaung towards
Indaw on the right flank of
NCAC. On July 26, the American 3rd Battalion of the Marauders made a significant gain by capturing the northern airfield at Myitkyina and over the next week Japanese resistance was noticeably weaker. On August 3, General Genzo Mizukami ordered the town abandoned and took his life in a literal compliance to "defend Myitkyina to the death" as the Chinese and US forces gradually cleared the city and the surrounding area of Japanese troops. ==Aftermath==
