cross abreast but offered the safest river crossing, as the Forth widened to the east and the marshland of Flanders Moss lay to the west. The Scots waited as the English knights and infantry, led by Cressingham, with Sir Marmaduke Thweng and Sir Richard Waldegrave, began to make their slow progress across the bridge on the morning of 11 September. It would have taken several hours for the entire English army to cross. Wallace and Moray waited, according to the Chronicle of Hemingburgh, until "as many of the enemy had come over as they believed they could overcome". When a substantial number of the troops had crossed (possibly about 2,000) the attack was ordered. The Scots spearmen came down from the high ground in rapid advance and fended off a charge by the English heavy cavalry and then counterattacked the English infantry. They gained control of the east side of the bridge and cut off the chance of English reinforcements to cross. Caught on the low ground in the loop of the river with no chance of relief or of retreat, most of the outnumbered English on the east side were probably killed. A few hundred may have escaped by swimming across the river. Marmaduke Thweng managed to fight his way back across the bridge with some of his men. Surrey, who was left with a small contingent of archers, had stayed south of the river and was still in a strong position. The bulk of his army remained intact and he could have held the line of the Forth, denying the Scots a passage to the south, but his confidence was gone. After the escape of Sir Marmaduke Thweng, Surrey ordered the bridge to be destroyed, retreated towards Berwick, leaving the garrison at Stirling Castle isolated and abandoning the Lowlands to the rebels. James Stewart, the High Steward of Scotland, and Malcolm, Earl of Lennox, whose forces had been part of Surrey's army, observing the carnage to the north of the bridge, withdrew. Then the English supply train was attacked at The Pows, a wooded marshy area, by James Stewart and the other Scots lords, killing many of the fleeing soldiers. The Stirling Bridge of that time is believed to have been about 180 yards upstream from the 15th-century stone bridge that now crosses the river. Four stone piers have been found underwater just north () and at an
