Neither Sir Kiel nor the king could resist their pleadings, and ere the sun of spring had shed its influence on the heart of man as well as the hardened earth, there were many who mourned that a separation had taken place, who wished that fatigue and anxiety had still been met together.
Many weeks before King Robert retreated to the island of Rathlin, Sir Nigel Bruce had conducted his precious charge in safety to the castle of Kildrummie, whose feeble garrison gladly flung open their gates to receive them.
It was a strong fortress situated on a circular mount, overhanging the river Don, which at that point ever rushed darkly and stormily along; the mount, though not steep, was full two miles in circumference, from base to brow occupied by the castle, which was erected in that massive yet irregular form peculiar to the architecture of the middle ages.

A deep, broad moat or fosse, constantly supplied by the river, defended the castle wall, which ran round the mound, irregularly indeed, for there were indentations and sharp angles, occasioned by the uneven ground, each of which was guarded by a strong turret or tower, rising from the wall.

The wall itself was some four-and-twenty feet in height, and nine in thickness, consequently the spaces between the turrets on the top of the wall formed broad level platforms, which in case of a siege were generally kept strongly guarded.

Facing the east, and commanding a view of the river and adjacent country, stood the barbacan gate and drawbridge, which latter was further defended by strong oaken doors and an iron portcullis, forming the great gate of the castle wall, and the principal entrance into the fortress.

Two towers of immense strength, united by a narrow, dimly-lighted passage, guarded this gate, and on these depended the grate or portcullis, which was lowered or raised by internal machinery.
