Quebec, opposite Wolfe's Cove. The arming of this battery
was a stupendous piece of work. The guns had to be taken
round by sea, out of range of the Island Battery, hauled
up low but very dangerous cliffs, and then dragged back
overland another mile and a quarter. The directing officer
was Colonel Gridley, who drew the official British maps
and plans of Louisbourg in 1745, and who, thirty years
later, traced the American defences on the slopes of
Bunker's Hill. Du Chambon had attempted to make an attack
on Gorham's Post as soon as it was established. His idea
was that his men should follow the same route as the
British guns had followed--that is, that they should run
the gauntlet between the British fleet and army, land
well north of Gorham's Post, and take it by surprise from
the rear. But his detachment, which was wholly inadequate,
failed to strike its blow, and was itself very nearly
cut off by Warren's guard-boats on its crest-fallen return
to Louisbourg.

Gridley's Lighthouse Battery soon over-matched the Island
Battery, where powder was getting dangerously scarce.
Many of the French guns were knocked off their mountings,
while the walls were breached. Finally, the British
bombardment became so effective that Frenchmen were seen
running into the water to escape the bursting shells. It
was now past the middle of June, and the siege had lasted
more than a month. The circle of fire was closing in on
the beleaguered garrison. Their total effectives had sunk
to only a thousand men. This thousand laboured harder in
its losing cause than might have been expected. Perhaps
