μάχεσθαι
With the use of this verb ‘to fight’, we can see that the anxiety is so great among the Achaeans that they fear large-scale attack, and not just a spying mission or an ambush. The fact that they have put seven hundred men on guard duty also reflects their concern that the Trojans will make an all-out assault at night. During the intense battle that occurs the following day, Agamemnon also wonders if the Trojans will stop fighting when night falls (Iliad 14.78–79).
