Bill, thanks for the response. The question came up for me in the Braddock's Defeat scenario. It made no sense that artillery could fire down the road over friendly units. House rules are easy for me as I only play my wargames solo. Before adding house rules, however, I want to make sure that I understand what the designer had in mind in the original rules. BTW, I am enjoying Bloody Mohawk very much. Simple rules. Easy setup. Great for filling small parcels of gaming time.
