Wallace's instructions were that so soon as the work had fairly begun, Grahame, with Archie and half the band, was to hurry off to seize the gate of Ayr, feigning to be a portion of the guard at the barn.
When they approached the spot they saw that the wooden building was brightly lit up with lights within, and the English guard, some fifty in number, were standing carelessly without, or, seated round fires, were carousing on wine which had been sent out by the revellers within.
The Scotch stole up quietly.

Wallace's party, composed of half the strength, handed their bundles of straw to the men of Grahame's company; then with a sudden shout they fell upon the English soldiers, while Grahame's men, running straight to the door of the barn, threw down their trusses of straw against it, and Sir John, snatching down a torch which burned beside the entrance, applied fire to the mass, and then, without a moment's delay, started at a run towards the town.

Taken wholly by surprise the English soldiers were slain by Wallace and his men almost before they had time to seize their arms.

Then the Scots gathered round the barn.

The flames were already leaping up high, and a terrible din of shouts and cries issued from within.
