William Shakespeare: Coriolanus, Act I, Scene VII
Titus Lartius, having set a guard upon Corioli, going with drum and trumpet toward Cominius and Caius Marcius, enters with Lieutenant, other Soldiers, and a Scout
So, let the ports be guarded: keep your duties,
As I have set them down. If I do send, dispatch
Those centuries to our aid: the rest will serve
For a short holding: if we lose the field,
We cannot keep the town.
