Colonel Abraham Creichton, although an old man, had fortified the castle and garrisoned it with his tenants and retainers. Lord Galmoy arrived at Belturbet with a considerable force belonging to King James’s army, but found the roads so boggy as to be impassable for cannon. He therefore decided to make some mock guns by which to frighten the garrison into submission. They were manufactured out of tin, measured about a yard long and 8 inches in the bore. They were bound together with fine cord twisted round them, and the whole covered with a kind of buckram to represent the colour of a real cannon. To this sham artillery sixteen horses were harnessed and they were brought to Crum with a great show of difficulty and much apparent urging of the animals. As soon as they were within ordinary range of the fortress Lord Galmoy demanded its surrender, and upon being refused he tried to fire one of his fraudulent guns with a wooden bullet, but it burst and nearly killed the gunner. He then began a systematic siege and sent messengers to Enniskillen to demand that garrison’s surrender too. The governor of the town at once despatched two hundred firelocks to relieve the castle of Crum. Some were sent by water and some by land during the night, but daylight had arrived before they reached their destination. The besiegers opposed their landing, but nevertheless they forced their way into the castle with the loss of only one boatman, while Lord Galmoy’s party lost several. A sally was at once made from the fortress, and the besiegers were driven from their trenches with a loss of thirty or forty men, and the garrison captured the mock guns and took two suits of armour and several other valuable things. Lord Galmoy then retreated to Belturbet. Colonel Creichton’s son David, then a lad of eighteen, greatly distinguished himself during the conflict. Although the castle was unprovided with cannon, great execution was done by the long fowling-pieces generally used for wild fowl on the lake. Lord Galmoy was standing on a hill about an English mile distant from the castle, with a glass of wine in his hand, which he was about to drink to the confusion of the garrison, when a fowler from the fortress shattered the glass he was raising and killed the man beside him. At this time a Captain MacGuire was prisoner at Crum, and Lord Galmoy proposed to Colonel Creichton to exchange Captain Dixey for him. This was agreed to, but when MacGuire was sent, Lord Galmoy, instead of returning Dixey, had him hanged with a cornet named Charleton. Captain MacGuire was so disgusted with the treachery that he returned to Crum and threw up his commission in James’s army. Lord Galmoy also enticed Colonel Creichton to a parley, and would have put him to death, too, had not Lord Mountcashel rescued the old man and conducted him safely back to his castle.
