Wow , some great suggestions there, thanks for all who responded.
the 33rd I will discount as they didn't see any action in the peninsular
the 68th were a light regiment and I don't have the correct figures to paint a light battalion
the coldstream guards are a good candidate though
the 44th 2nd battalion saw lots of action in the peninsular
the 11th foot are a good choice as well as are the 27th
despite the excellent painting and the provided flags ( thank you very much ) , I'm afraid I wont be doing the south essex
the 88th , 3rd, 5th and 23rd are also all good choices.
Hmm, choices, choices.
Well after a bit of researching I think "The Devils Own", the 88th Connaught Rangers are going to be the ones.
thanks for all the replies
