Given that there is a vast amount of information on Gettysburg, how about adding your impressions to a Brit's understanding of the battle? I've read loads on the battle recently and I'd be interested to hear your views on the most important single element to the battle. Chamberlain's defence? Failure to co-ordinate attacks around Pickett's charge? The actions at East Cavalry Field? Buford's determined stand? I'd love to hear your views!
