39.51 · Hostility, Strife · Ambush
ambush, planning a secret attack concealing oneself or proceeding secretly, while waiting for an appropriate opportunity to attack Since ambushing is such a widespread method of warfare and private attack, there is usually little or no difficulty involved in finding an appropriate term and using it in what might be called an anticipatory sense, that is to say, the employment of an ambush despite the fact that it was not finally successful.
