It was calculated that the scope of this
operation would not be greater than three weeks, and on the 27th the
army were equipped with twenty-one days' supplies, of which two were
carried by the troops, five by the regimental barges, and fourteen in
the army transport sailing-vessels. All surplus stores were deposited at
Royan island, where a field hospital was also formed.

The Expeditionary Force which was thus concentrated, equipped, and
supplied for the culminating moment of the River War, was organised as
