obtained possession of the first defences and was making an attack against
the second line. The outer wall was twelve feet in thickness, and thirty
feet above the court; outside the height was considerably greater, as
there was a moat faced with stone fifteen feet deep entirely surrounding
it, and containing seven or eight feet of water.

Walls ran half across the outer court, and, from the end of these, light
wooden bridges formed a communication with the wall of the inner court, so
that in the event of the outer wall being stormed or the gates being
carried by assault, the defenders could retire to the inner defences. The
ends of these bridges rested upon irons projecting from the wall, and so
arranged that they could be instantly withdrawn when the last of the
defenders had crossed over, when the bridges would at once fall into the
court-yard below. The inner wall was twelve feet higher than the outer
one, and, like it, was provided with a crenellated battlement four feet
high; there were projecting turrets at each corner, and one in the middle
of each side.

The keep rose twenty feet higher than the wall of the inner court. The
lower portions of the cross walls of the outer court were carried on as
far as the inner wall, thereby dividing the space into four; strong gates
gave communication from one to the other. Into these could be driven the
cattle of the tenantry, and one of them contained a number of huts in
which the tenants themselves would be lodged. The court-yard facing the
entrance was the largest of the areas into which the space between the
outer and inner walls was divided, extending the whole width between the
outer walls. Here the military exercises were carried on. Along the wall,
at each side of the gate, were a range of stables for the use of the
horses of guests, with rooms over them for the use of their retainers.
There was a strong exterior work defending the approach to the drawbridge
