The musketeers and crossbowmen on the boat tried to provide support by firing from the boats. Though the light armor and the shields of the natives were vulnerable to European projectile weapons, the barrage had little effect, as they were firing from an extreme distance and the natives easily avoided them. Due to the same distance, Magellan could not command them to stop and save their ammunition, and the musketeers and crossbowmen continued firing for half an hour until their ammunition were exhausted.
