The commander of the Tetrarch made his report, and was then ordered to take command of four Valentines and two Tetrarchs which had recently arrived and once again attempt to breach the French defences. The tanks followed the road leading to the defensive line and then attempted to out-flank the line by advancing from the right-hand side, using several hills as cover; the artillery pieces were able to turn and face the assault, however, and one Valentine and one Tetrarch were hit and destroyed. The remaining tanks exchanged several volleys of fire with the artillery pieces before retreating back to their original positions. The French line was eventually broken by 29th Brigade, aided by an amphibious assault by Royal Marines; the remaining tanks of 'B' Squadron, two Valentines and three Tetrarchs, remained in defensive positions until the afternoon of 6 May, coming under sporadic artillery fire which disabled another Valentine. The squadron played no further part in the battle, as the Vichy French authorities negotiated a formal surrender the following day, although French troops would continue to engage the British occupying force in guerrilla warfare until late November. 'C' Squadron suffered heavy casualties during the invasion; only one Valentine and three Tetrarchs out of twelve tanks were functional by 7 May, and the squadron had suffered seven killed and six wounded. It remained in Madagascar until early 1943, when it was shipped to India and took part in the Burma Campaign as part of 29th Brigade.
