Sergeant Major Matsui

Sergeant Major Matsui served in the 2nd chutai, 2nd Daitai commanded by Yonesuke Fukuyama, as fighting in China broke out. This unit was equipped with Kawasaki Ki-10s.

On 11 March 1938 13 Ki-10s, led by the new 2nd Daitai commander, Major Tamiya Teranishi, escorted bombers to Sian. Lieutenant Yonesuke Fukuyama’s shotai of three Ki-10s encountered nine Chinese fighters and engaged them in a dogfight at 18,000 ft. Fukuyama engaged the leader (reportedly a Soviet volunteer) for ten minutes before finally shooting him down with eight bursts at 2,000 ft (according to some sources the enemy aircraft was a Gladiator). He then shared an I-15 with Sergeant Yohei Machiba. Sergeant Major Matsui claimed two more I-15s while Warrant Officer Umekawa claimed a forth I-15.

Matsui ended the war with 2 biplane victories.
