3. The main body will consist of nine companies of infantry, one battery
and two platoons of artillery, and two Gatling guns.

4. The trains following the main body will be under the direction of the
brigade quartermaster, and their order of march will be:--

Hospital train.
Ammunition column.
Supply and baggage wagons.

The rear-guard will be composed of one company of infantry. A detachment
from it will protect exposed flanks of the train. If horses can be procured
for them, the commanders of the advance and rear guards will be mounted.

The above disposition for each day's march will be conformed to, unless
otherwise ordered.

By command of Brigadier-General Schwan.

GROTE HUTCHESON, _Captain and Assistant Adjutant-General._

As Captain Macomb's cavalry had not arrived at the hour appointed for our
start, we set off without him. And in fact there was little need of his
services on that day, our march being through a section of the island
already cleared of Spanish troops, and exceedingly slow and wearisome,
besides.
