Onslaught is a military term that refers to an attack against an enemy. It's safe to say that no one wants to be caught on the receiving end of an onslaught, because there will be lots of danger, destruction and probably death.
attack (v). To attack is to begin hostilities of any kind. A general invades a country by marching in troops; he attacks a city by drawing up an army against it; he assaults it by hurling his troops directly upon its defenses. Assail and assault, tho of the same original etymology, have diverged in meaning, so that assault alone retains the meaning of direct personal violence.
