In May 1944, British forces mounted a counter-offensive that drove Japanese troops back to Burma by July, and Chinese forces that had invaded northern Burma in late 1943 besieged Japanese troops in Myitkyina.
Xa en maio as forzas británicas montaron unha contraofensiva que fixo retroceder ás tropas xaponesas ata Birmania, e as forzas chinesas que invadiran o norte de Birmania a finais de 1943 asediaron as tropas xaponesas en Myitkyina.
