In 1754, John Pitcairn was a young captain in the British Marine corps. He fought in the French and Indian war, but I can't find much about his postings. He's listed as being on the HMS Lancaster during the capture of Louisbourg - that's in Canada. No record of him being on the 'American' side of the colonies but it seems he did some covert work as well - that would explain the lack of details. ** **
