Colonel Miller was some twenty miles from the supplies, but not deeming it prudent with the slender reinforcements he had received, and the still scantier provisions, to proceed, remained on the battle field, and sent another messenger declaring that the communication was open, and it required only a few more men and a supply of provisions, to keep it so. The next evening, the messenger returned, bringing instead of provisions a peremptory order to return to Detroit. It is doubtful whether Colonel Miller ought not to have advanced without waiting for further reinforcements, and formed a junction with Captain Brush, who had an abundance of provisions, and a detachment of a hundred and fifty men. But, after the communications were established, he did not probably see so much necessity for dispatch as for security. But General Hull seemed to be laboring under a species of insanity. After sending forth two detachments to open his communications, and finally succeeding, he deliberately closed them again, and shut from his army all those provisions, the want of which he a few days after gave as a reason for surrendering. The rapid concentration of the enemy's forces, in front of him, might have been given as a sufficient cause for suddenly calling in all his troops to defend Detroit, had he not two days after sent Colonel McArthur, accompanied by Cass, with a detachment of four hundred men, to obtain by a back, circuitous and almost wholly unknown route through the woods that which Colonel Miller had secured, and then been compelled to relinquish. [Sidenote: Aug. 7.] When General Hull recrossed the river to Detroit, he left some hundred and fifty, convalescents and all, "to hold possession of that part of Canada," which he had so gallantly won, "to defend the post to the last extremity against musketry, but if overpowered by artillery to retreat."[18] In the mean time, General Brock, the commander of the British forces, approached, and began to erect a battery opposite Detroit to protect his army, and cover it in crossing the river. Not a shot was fired to interrupt his proceedings, no attempt made to destroy his shipping which had arrived. Daliba offered "to clear the enemy from the opposite shores from the lower batteries," to which General Hull replied, "I will make an agreement with the enemy, that if they will not fire on me I will not fire on them." Major Jessup asked permission to cross the river and spike the guns, but this was considered a too desperate undertaking. In short, every project that was proposed was rejected, and the twenty-four pounders and the howitzers slept dumb on their carriages, in the midst of these hostile preparations of the enemy.
