On July 26, 1944, Chinese soldiers of the XXth Army Group attacked Laifengshan, a mountain rising five hundred feet above the southwest corner of Tengchong. The Japanese had stationed their artillery on the mountain, making its capture an essential prerequisite to action against the city. At 1200 hours on the twenty-sixth, the first of four waves of American fighters arrived overhead. Airplanes and artillery pounded Japanese positions. Demonstrating what they had learned in months of hard fighting, the Chinese advanced quickly in the wake of these attacks. They advanced as whole regiments instead of piecemeal. They did not stop to loot the dead. They reached the summit by nightfall and repelled a counterattack the next day. Brigadier General Dorn called it the best-coordinated attack of the entire Salween Campaign.
