B-25s assigned to the 3^rd Bomb Squadron crossed “the Hump” and then made their way to Kweilin. The planes arrived at their new base on September 8, 1944—the same day the Japanese 11^th Army overran Lingling, both the town and the airfield, as part of their massive Operation ICHIGO offensive. Then began their advance toward Kweilin, about 125 miles farther to the southwest. The 3^rd Squadron's bombers flew only four missions before Kweilin was evacuated, all against towns in the path of the enemy drive. Final evacuation and demolition procedures began on September 14, as 3^rd Squadron personnel began their move to Peishiyi by air transport, railroad, truck convoy, and the squadron’s B-25s.

On August 26, 1944, members of the 3rd Bomb Squadron flew "the Hump" of the treacherous Himalayas, making the move from Chabua in Assam, India, to Kweilin (Guilin) in Kwangsi (Guangxi) Province, China. Flying the Hump took planes over rugged terrain, often through violent storms, sudden down drafts, and snow and ice at higher altitudes. It was some of the most dangerous flying in the world―so dangerous, in fact, that every flight over the Hump was logged as a combat mission. The planes all made it across safely, and squadron personnel arrived at their new base on September 1.
