Alexander's army attacked Assur, held by a variety of Persian units from across the empire, which was the capital of Assyria. Despite a failed initial attack that cost both sides heavily, Alexander renewed the attack with more spearmen, but failed, and now General Karademas took over his camp. Alexander, counterattacking from Cappadocia with a new army, faced the governor, who had only a small garrison, and destroyed his army, encircling Karademas' force in the process. The encircled Persian army was massacred, and Alexander won, although at a tremendous cost, a pyrrhic victory.
Alexander then proceeded to invade the city again, attacking Caspar's army with his battle-hardened (now including Macedonian lancers) army, and slaughtered the enemy, taking over Assyria.
