On the 18th October, the very day on which this last despatch was dated, General de Rottenburg informed Sir George Prevost, by letter, that the Staff-Adjutant's account, by which he had been induced to give the directions to General Vincent to retreat to York, preparatory to falling back on Kingston, was false and scandalous. As soon as it was thus ascertained at head-quarters at Montreal, what the real nature of General Procter's disaster was, the Commander of the forces having also reason to believe, from the information transmitted to him by General de Rottenburg, that the enemy had designs upon York from Sackett's Harbour, instructions, dated the 29th October, were sent to that officer, directing him to prevent General Vincent's further retreat, and to order him to occupy both Burlington and York with the force under his command. The orders, which were accordingly sent from General de Rottenburg to General Vincent to that effect on the 1st November, were received by him on the 4th, and he in consequence remained in the position he then occupied at Burlington Heights, which undoubtedly led afterwards to the recovery of the Niagara frontier. From the above correspondence it incontrovertibly appears, that the orders transmitted from the Commander of the forces, through General de Rottenburg to Major-General Vincent, were the real and only cause of that officer's _not retreating_ to York, and of his continuing to hold his position at Burlington; which, as appears by his own letter of the 27th October, before referred to, he was preparing to leave on the 1st November. Sir George Prevost's orders to General Vincent, to fall back upon Kingston, had not reached him on the 23rd October; previous to which, his orders to retreat had been discretionary. On the 27th he was preparing to obey them, and on the 4th of November he received orders to remain where he was. There cannot, therefore, be a doubt of the gross incorrectness of all the Reviewer's statements,[69] of the repeated peremptory orders to retreat; of the advice which the firmness of General Procter and others had induced them to give General Vincent to disobey those orders, and of his being persuaded upon their responsibility to adopt it.
