Well, aside from not eating enough fiber,… no, seriously though,… you have to remember that the British Army had to be augmented due primarily to the natural turn-over that occured in the ranks (death, death, more death, being drummed out, and a little bit of retirement) and this was normally carried out in two different ways: "first, existing regiments can be built up by the addition of personnel in the hope that the new recruit will gain experience and coolness under fire from the seasoned veteran. The second, and usually more desirable, is to raise new battalions, and endeavour to give them adequate training before exposing them to the rigors of combat.,… British regiments were allowed to add new companies, increase the number of privates per company from 38 to 56, or a combination of these."

So, they too were utilized almost like a third option.
