“It’s a chief principle in military affairs,” said he, “to go where ye are least expected.  Forth is our trouble; ye ken the saying, ’Forth bridles the wild Hielandman.’  Well, if we seek to creep round about the head of that river and come down by Kippen or Balfron, it’s just precisely there that they’ll be looking to lay hands on us.  But if we stave on straight to the auld Brig of Stirling, I’ll lay my sword they let us pass unchallenged.”

The first night, accordingly, we pushed to the house of a Maclaren in Strathire, a friend of Duncan’s, where we slept the twenty-first of the month, and whence we set forth again about the fall of night to make another easy stage.  The twenty-second we lay in a heather bush on the hillside in Uam Var, within view of a herd of deer, the happiest ten hours of sleep in a fine, breathing sunshine and on bone-dry ground, that I have ever tasted.  That night we struck Allan Water, and followed it down; and coming to the edge of the hills saw the whole Carse of Stirling underfoot, as flat as a pancake, with the town and castle on a hill in the midst of it, and the moon shining on the Links of Forth.

“Now,” said Alan, “I kenna if ye care, but ye’re in your own land again.  We passed the Hieland Line in the first hour; and now if we could but pass yon crooked water, we might cast our bonnets in the air.”

In Allan Water, near by where it falls into the Forth, we found a little sandy islet, overgrown with burdock, butterbur and the like low plants, that would just cover us if we lay flat.  Here it was we made our camp, within plain view of Stirling Castle, whence we could hear the drums beat as some part of the garrison paraded.  Shearers worked all day in a field on one side of the river, and we could hear the stones going on the hooks and the voices and even the words of the men talking.  It behoved to lie close and keep silent.  But the sand of the little isle was sun-warm, the green plants gave us shelter for our heads, we had food and drink in plenty; and to crown all, we were within sight of safety.

As soon as the shearers quit their work and the dusk began to fall, we waded ashore and struck for the Bridge of Stirling, keeping to the fields and under the field fences.

The bridge is close under the castle hill, an old, high, narrow bridge with pinnacles along the parapet; and you may conceive with how much interest I looked upon it, not only as a place famous in history, but as the very doors of salvation to Alan and myself.  The moon was not yet up when we came there; a few lights shone along the front of the fortress, and lower down a few lighted windows in the town; but it was all mighty still, and there seemed to be no guard upon the passage.

I was for pushing straight across; but Alan was more wary.

“It looks unco’ quiet,” said he; “but for all that we’ll lie down here cannily behind a dyke, and make sure.”
