reenforce

The garrison of that city was reduced as much as possible to re-enforce his column.

Around those woods Blucher was looked for to re-enforce the English, and just in time he came up.

Eventually "a strong party" was sent out from England to re-enforce Phillips and "push the work vigorously."

It was an injudicious action, but both of us at once prepared to defend and re-enforce it, of course.
