River. Both brigs were captured, although Detroit subsequently ran aground and was set on fire to prevent it being recaptured. Brock feared this might presage an attack from Buffalo and galloped to Fort Erie. Although he soon realised that there was no immediate danger from Smyth in Buffalo, and returned to his headquarters in Niagara that night, it was mistakenly reported to Van Rensselaer that Brock had left in haste for Detroit, which Major General William Henry Harrison was attempting to retake. Van Rensselaer decided to launch an attack at 3 a.m. on 11 October, even though Colonel Van Rensselaer was ill. On 10 October, Van Rensselaer sent orders to Smyth to march his brigade to Lewiston in preparation for the attack "with every possible dispatch." Smyth set out upon receipt of the letter. However, in foul weather, he chose a route to Lewiston that was so bad that abandoned wagons could be seen "sticking in the road." The same tempestuous weather drenched Van Rensselaer's troops as they stood and waited to embark. One of the lead boatmen, a Lieutenant Sims, rowed his boat away and deserted the army, taking with him most of the oars. By the time the oars could be replaced, the attack had to be postponed. Colonel Van Rensselaer set the second attempt for 13 October. Smyth received word the attack had been postponed at 10 a.m. on 11 October. He then turned back to his camp at Black Rock, New York, near Buffalo, rather than press on to Lewiston. He wrote to Van Rensselaer on 12 October that his troops would be in condition to move out again on 14 October, a day after the postponed attack was to be launched. Brock's preparations Brock was aware of the failed attempt to cross the river on 11 October but was not certain this was not a mere demonstration to distract him from a major attack elsewhere. On 12 October, Major Thomas Evans (the Brigade Major at Fort George) crossed the Niagara River under a flag of truce to request an immediate exchange of prisoners taken in Elliot's raid on the British brigs three days before. He attempted to see Colonel Solomon Van Rensselaer but was told the Colonel was ill. Instead, he was met by a man who claimed to be General Stephen Van Rensselaer's secretary, Toock. Toock was probably Major John Lovett (Van Rensselaer's private
