determined on attacking them separately. The Arequipa detachment, under
Colonel Hera, was fallen in with at Maribe, and immediately routed, the
result being that nearly the whole were killed or taken prisoners,
together with four hundred mules and their baggage. In this affair we

This action was fought none too soon, for before it was over the other

the royalists remounted their mules and decamped, in the direction of
Moquega.

On the 22nd Miller pursued the runaway royalists, and, on the 24th,
entered Moquega, by a forced march of nearly a hundred miles, where he
