Why Hull withdrew to Detroit

(from The Defense of Hull, p. 74)

It must be remarked, that from the time the army arrived at Detroit, not one pound of provisions had been received. From the moment the declaration of war was known to the enemy, he had intercepted the only line of communication, and thus cut off all supplies.

Re-enactors as American troops

(from The Defense of Hull, p. 83 - 84)

... I abandoned Canada because I had ascertained that I should soon be surrounded by an overwhelming force; because my communication, if I remained where I was, would inevitably be cut off; and because I found that the few regulars and militia I commanded, were to be left to carry on, without any assistance or co-operation, the offensive war, which the United States had declared against one of the most powerful nations on earth.
