it was such a tight area you'd still have Ramsey, his boys and the dogs all in front of you. Hell in the hallway you'd have the dogs getting in each others way. The 50 best killers from Seagull shit island can't handle three dogs, a shirtless Ramsey and three or four guys standing behind him?
Also your understanding of infantry/archery attacks is pretty poor. Most archery attacks were done en mass like an artillery strike. You used the archers to thin out the ranks, then had the infantry go in to finish them off before they could regroup. The Lord of the Rings style archer sniper is very rare and not something you'd rely on while you have your own men engaged in melee fighting, unless you don't care about losing some of your own guys while doing it. I go to the range and shoot guns and bows recurve and compound, it is much easier to be consistent with a gun and get much tighter groupings. The accuracy of an arrow can be affected by just as many things as can affect a bullet but to a greater extent.
