Thank you kindly for your response. Like you, Alexander is also a descendant of mine. To date my research in Canada and UK has not thrown any light on the transcript of the Court Martial. I was able to gather your copy of the transportation authorisation record,will keep you in touch should I resolve the details of the Trial. I suspect that your comment of "desertion" may well be correct, however evidence to date has indicated that even during 1810, the offence would have been a capital crime.
