A powder magazine was hacked out of the bedrock beneath the Joannes bastion. All the construction within the fort was of stone. A wooden palisade protected an area outside the fort between the southern wall and the lake shore. This area contained the main landing for the fort and additional storage facilities and other works necessary for maintenance of the fort. When it became apparent in 1756 that the fort was too far to the west of the lake, the French constructed an additional redoubt to the east to enable cannon to cover the lake's narrows. Analysis By 1758, the fort was largely complete; the only ongoing work thereafter consisted of dressing the walls with stone. Still, General Montcalm and two of his military engineers surveyed the works in 1758 and found something to criticize in almost every aspect of the fort's construction; the buildings were too tall and thus easier for attackers' cannon fire to hit, the powder magazine leaked, and the masonry was of poor quality. The critics apparently failed to notice the fort's significant strategic weakness: several nearby hills overlooked the fort and made it possible for besiegers to fire down on the defenders from above. Lotbinière, who may have won the job of building the fort only because he was related to Governor Vaudreuil, had lost a bid to become Canada's chief engineer to Nicolas Sarrebource de Pontleroy, one of the two surveying engineers, in 1756, all of which may explain the highly negative report. Lotbinière's career suffered for years afterwards. William Nester, in his exhaustive analysis of the Battle of Carillon, notes additional problems with the fort's construction. The fort was small for a Vauban-style fort, about wide, with a barracks capable of holding only 400 soldiers. Storage space inside the fort was similarly limited, requiring the storage of provisions outside the fort's walls in exposed places. Its cistern was small, and the water quality was supposedly poor. Military history French and Indian War In August 1757, the French captured Fort William Henry in an action launched from Fort Carillon. This, and a string of other French victories in 1757, prompted the British to organize a large-scale attack on the fort as part of a multi-campaign strategy against French Canada. In June 1758, British General James Abercromby began amassing a large force at Fort William Henry in preparation for a military campaign directed up the
