The enemy were evidently in great strength.
In an instant everyone was at his post, and steady volleys were poured into the darkness, on the garden side of the fort, whence the chief attack seemed to be coming.

Suddenly a strong light was seen near the gun tower, and it was found that the enemy had heaped faggots against the walls.

These, being constructed partly of wood, gradually caught fire.
Mr.Robertson, with some of the levies, horse keepers, and servants, at once set to work to extinguish the flames; but the conflagration was too much for them.

The troops in reserve were then sent to aid them.

The work was dangerous and difficult, the flames raged fiercely, and the enemy kept up a tremendous fire from behind the walls of the summer house.
