Brock, smarting under restraint and handcuffed by red tape, was compelled to look on while the enemy brought up reinforcements, powder, shot, provisions and other munitions of war, by water to Lewiston. General Van Rensselaer, in command of the American forces at Lewiston, wrote to the President stating that by "keeping up a bold front he had succeeded in getting from General Sheaffe at Fort George the uninterrupted use of the lakes and rivers." The strategic advantage to the enemy of this cessation of hostilities and the privileges conceded was enormous. Prevost realized his error too late. The following year, conceiving it then to be his special mission to borrow our dead hero's policy, he attacked Sackett's Harbour, but his "cautious calculation" was, of course, rewarded by ignoble defeat, and ultimately, after the Plattsburg fiasco, by a court-martial. In his civil administration of Canada Sir George Prevost may have been a success; as a soldier he was a sad failure. Isaac was daily proving the truth of the precept, recognized by all men sooner or later, that life's values lie not so much in its victories as in its strife. Though Brock awoke after Detroit to find himself famous, and a hero whose prowess far exceeded that of his ancestor, the Jurat of the Royal Court of Guernsey, over whose exploits he used to ponder seated on the Lion's Rock at Cobo, he was still the same "Master Isaac," still the "beloved brother." Separation from his kinsmen only served to draw him closer. Crossing Lake Ontario gave him the opportunity he longed for. He wrote to his brothers collectively, telling them the sundry details of his success, "which was beyond his expectation." He hoped the affair would meet with recognition at the War Office. Though admitting it was a desperate measure, he told them "it proceeded from a cool calculation of the _pros_ and _cons_," and as Colonel Procter had opposed it, he was not surprised that envy now induced that officer "to attribute to good fortune what in reality was the result of my own knowledge and discernment." But praise and honours, though sweet to our hero, who after all was only mortal, were secondary to the fact that he would be in a position to contribute something to the comfort and happiness of his brothers. The value of the "treasure" captured at Detroit was placed at L40,000. Brock's share of this was a substantial sum.
