Note 410 — Chapter XIV
Reading edition
"It does not appear that the fortifications of Quebec were of much importance till after the year 1690, when eleven stone redoubts which served as bastions, were erected in different parts of the heights of the Upper Town. The remains of several of these redoubts are still in existence. They were connected with each other by a strong line of cedar picketing, ten or twelve feet high, banked up with earth on the inside. This proved sufficient to resist the attacks of the hostile Indians for several years."—Lambert's Travels, vol. i., p. 39.
"In 1720 a more extensive system of fortification was commenced, under the direction of M. de Lery."—Smith's Canada, vol. i., p. 184.
