But across the lines Aeneas called his comrades,
glancing fast at Deiphobus, Paris, brave Agenor,
all the Trojan captains who backed Aeneas here,
and fighters followed close behind like flocks
that follow the lead ram, leaving the pastureland
to drink at springs, and the shepherd’s heart exults.
So now the heart of Aeneas leapt inside his chest
when he saw the flocks of fighters crowding in his wake.

– Homer

The Iliad, Book 13, lines 567- 574. Aeneas is delighted and relieved when Trojan troops come to reinforce him. The image of a shepherd and his flocks following the lead ram is used to good effect in an epic simile.
