A regular infantry brigade costs around 100 million a year.

The federal infantry brigade he had been ordered to rout from the field had somehow turned into an entire federal division.

During the war, most divisions became triangular - one infantry brigade with three infantry regiments rather than two infantry brigades of two regiments (a square division).

Each infantry brigade was about 3,600 strong, each cavalry brigade was about half that size.

This was organised as a mounted infantry brigade.
