An enemy threw a grenade at their position which landed 10 meters from them; it detonated, knocked them to the ground, wounded Higgins, and Robinson was further wounded.Shortly thereafter the three were joined by SSG James Roberts and SPC Christopher Gathercole. Another grenade was thrown by an enemy which landed a few feet from Higgins and Robinson. Petry, knowing the risk to his life, moved toward the grenade, picked it up, and attempted to throw it in the direction of the enemy.
