A few days after his arrival Harry received orders to take a hundred and fifty men of his regiment, and to post himself at Kirkglen, which blocked a road by which it was thought Cromwell might send foraging parties westward. Harry asked that a detachment of cavalry might accompany him, but the request was refused. Kirkglen stood fifteen miles south of Edinburgh, and somewhat to its west. Harry left Jacob to command the main body of the regiment, and took with him the companies of Donald Leslie and Hugh Grahame, in the latter of which William Long was lieutenant. They sallied out from the western side of the camp at daybreak.
"I like not this expedition, Colonel Furness," Donald Leslie said. "The refusal to send cavalry with us is strange. Methinks I see the finger of that crafty fox Argyll in the pie. His faithfulness to the cause is more and more doubted, though none dare wag a tongue against him, and if it be true that he is in communication with Cromwell, we shall have the Roundheads, horse and foot, down upon us."
"There is a castle there, is there not," Harry asked, "which we might occupy?"
"Assuredly there is," Leslie replied. "It is the hold of Alan Campbell, a cousin of the man you pinked. It is that which adds to my suspicion. You will see, unless I am greatly mistaken, that he will not admit us."
Such, indeed, proved to be the case. Upon their arrival at Kirkglen, Leslie went in Harry's name to demand admittance to the castle for the royal troops, but Campbell replied that he had received no orders to that effect, and that it would greatly incommode him to quarter so large a number of men there. He said, however, that he would willingly entertain Colonel Furness and his officers. Leslie brought back the message, strongly urging Harry on no account to enter the castle and put himself in the hands of the Campbells. Harry said that even had he no cause to doubt the welcome he might receive at the castle, he should in no case separate himself from his men, when he might be at any moment attacked.
"It is a rough piece of country between this and Cromwell's post," Leslie said, "and he would have difficulty in finding his way hither. There is more than one broad morass to be crossed, and without a guide he would scarce attempt it. It is for this reason that he is so unlikely to send out foraging parties in this direction. It was this reflection which caused me to wonder why we should be ordered hither."
"Mike," Harry said, "you have heard what Captain Leslie says. Do you keep watch to-night near the castle gate, and let me know whether any leave it; and in which direction they go. I will place a man behind to watch the postern. If treachery is meditated, Campbell will send news of our coming to Cromwell."
