Siege warfare was an integral aspect of Rome's dominant military. The Romans used siege ramps, siege towers and battering rams in conjunction to assault enemy fortresses. Siege ramps provided stable mechanisms for siege engines to take position adjacent to enemy walls. Siege towers cleared the defender's ramparts of any resistance. Battering rams breached walls so that Roman infantry could assault the enemy. All of these machines would not have worked without the others. A prime example of the use of these machines is the siege of Masada during the Great Jewish Revolt.
