My Dear Charles,
I’m now two letters in your debt, the last of which dated the 16th instant came to hand two days ago. It makes your mother and I happy that you do not complain of bad health, God be praised, the family here enjoy the like great blessing.
The Militia-Law has arrived, but I have not yet seen it. Indeed, unless on my children’s account I have little to do with it. Except my wishes for the success of the British arms, which can only end with my last breath. I can not comprehend how a man of honour & honesty can ever change his allegiance. There are some preparations making at Detroit, and great ones at Malden for War. I hope it may not take place, yet I dread it much. The contracts at Malden for wood etc for furnishing say to repair the garrison & make a vessel, its thought will exceed 6,000 [pounds]. This will throw a good deal of ready money into this part of the country ….
The Indians have done a good deal of mischief in different quarters of the United States. The people of Detroit, not in the garrison, are much alarmed; Alice was here a few days ago. Poor woman, she suffers amazingly from fear, for I understand none of the town’s people will be received into the garrison. Alexander was over yesterday & says they are now taking precautions against Indian surprise, & therefore she is not so much alarmed. The guns, blunderbusses etc here are all loaded & in good order; I hate to be taken prisoner & he who attempts it, if openly may lose his life; having only my children & self we can not do much, but will try not to be surprised. I advised Captain McKee to move to Malden. There is too great risk here. I believe he moved yesterday. Most of Robert McDougall’s property is on this side. Poor Meldrum I think is much embarrassed. I think him in his heart a true British subject. The conduct of his boys bears hard on him.
Your tender Father,
