[E.B. O'Callaghan (1849)] On the ll,h, at break of day the Canadians and Indians advanced to within a quarter of a league of, and invested Fort Ontario, situated, as we have stated, on the right bank of the River Chouaguen. Sieur Decombles, sent at 3 o'clock in the morning to make arrangements for this siege and the attack, was killed, returning from his reconnoissance, by one of our Savages [a NipissingJ who escorted him and who took him in the dark, for an Englishman — a mishap which was rendered of the greatest consequence to us from the circumstance of carrying on a siege in America with one Engineer only that remained. Sieur Desandronius the surviving Engineer, ran a road through the woods, partly through swamps explored the evening before, for the purpose of conducting the artillery across. This road, commenced at 11 o'clock in the morning was finished at night and thoroughly completed next morning. The camp was established at the same time, the right resting on Lake Ontario covered by the same battery that protected our batteaux from attack; the left, on an impassable swamp. 1 Supposed to be a part of the celebrated Irish Brigade, then in the French service, and mentioned in the Deposition of a French Deserter, p03t p. 324; Bearn"s battalion was between 400 and 500 men. 2 Another account says — " Orders came for the Regiment of La Sarre to proceed to the Bay of Niaoure... We pro-ceeded on the 29th to encamp at l'lsle aux Aillo and arrived at the rendezvous on the 30th....
