Later in the year—August—Thompson’s Company was withdrawn from the front, owing to continued sickness, and replaced by Bredin’s Company.
Hawker’s Company served with Beresford’s Army. It was present at the battle of Albuera, and at the two unsuccessful sieges of Badajoz (May-June 1811).

May’s Company (under the command of 2nd Captain H. Baynes, May being employed on the Staff) accompanied the Army, in charge of the Reserve Ammunition.
The other eight companies did not join the Army at the front, except Raynsford’s for a short period.
