Before Craig left for England, amongst the matters he had discussed with Brock was that of possible trouble between the Indians in Canada and United States border citizens. Sir James Craig’s policy is outlined in a letter to Brock: “Upon every principle of policy our interests should lead us to use all our endeavors to prevent a rupture between the Indians and the subjects of the United States.” Brock appreciated the wisdom of this and followed it out. He instructed those under him, who had charge of territory inhabited by these Indians, to keep a tight rein on their maraudings and pillagings and did all he could to discourage border crime. But, doubtless to his amazement, in the summer of 1811, the government of the United States accused British officers in Canada of actually aiding and abetting the Indians in their lawlessness. Brock, naturally, had a hard enough row to hoe, for though he must deprecate the cruelty of the Indians, he was anxious to preserve friendliness with them, since, should war come, he desired them as allies, or at any rate, did not want them as enemies. His position was difficult. This was but one of the perplexities which the new administrator of Upper Canada had to face. Just about this time, domestic trouble caused him great anxiety. He had two brothers in London, William and Irving. They were partners in a private bank. Serious financial troubles had been caused by the wars in Europe, and in New York failures had been many. Brock, in a letter to his brother Irving, reporting these, prophesied a financial crash in London. He hoped they had “withheld their confidence in public stock.” Unfortunately, they had not, and owing to the depredations of Napoleon’s privateers upon the boats belonging to his banker-brothers, the latter had had to close their house. When the books were examined there was an item of £3,000, which appeared as a debt owed to the bank by Isaac Brock. This was really a personal loan by William Brock to Isaac, but as the transaction appeared in the books, Brock deemed himself liable. That was a small matter, however, compared to the trouble which the bank’s affairs had made between William and Irving. Irving blamed his brother William for the smash. Brock wrote from Canada to Irving imploring his kindliness to William. “Hang the world! It is not worth a thought,” he wrote. “Be generous, and find silent comfort in being so.” Brock knew how his brother William, who had been so kind to him, was suffering. “Why refuse him consolation”? his letter to Irving read. “Could tears restore him he would soon be happy.... My thoughts are fixed on you all and the last thing that gives me any concern is the call which Savery prepared me to expect from the creditors.” Great hearted Brock! It meant much to him just now to find £3,000, but the suffering of William and the breach between the brothers meant far more.
