Sir Robert Knolles had served in Brittany before, and he marshaled his men on the march with the skill and caution of the veteran soldier, the man who leaves as little as possible to chance, having too steadfast a mind to heed the fool who may think him overcautious. He had recruited a number of bowmen and men-at-arms at Dinan; so that his following was now close upon five hundred men. In front under his own leadership were fifty mounted lancers, fully armed and ready for any sudden attack. Behind them on foot came the archers, and a second body of mounted men closed up the rear. Out upon either flank moved small bodies of cavalry, and a dozen scouts, spread fanwise, probed every gorge and dingle in front of the column. So for three days he moved slowly down the Southern Road.

Sir Thomas Percy and Sir James Astley had ridden to the head of the column, and Knolles conferred with them as they marched concerning the plan of their campaign. Percy and Astley were young and hot-headed with wild visions of dashing deeds and knight errantry, but Knolles with cold, clear brain and purpose of iron held ever his object in view.

"By the holy Dunstan and all the saints of Lindisfarne!" cried the fiery Borderer, "it goes to my heart to ride forward when there are such honorable chances on either side of us. Have I not heard that the French are at Evran beyond the river, and is it not sooth that yonder castle, the towers of which I see above the woods, is in the hands of a traitor, who is false to his liege lord of Montford? There is little profit to be gained upon this road, for the folk seem to have no heart for war. Had we ventured as far over the marches of Scotland as we now are in Brittany, we should not have lacked some honorable venture or chance of winning worship."

"You say truth, Thomas," cried Astley, a red-faced and choleric young man. "It is well certain that the French will not come to us, and surely it is the more needful that we go to them. In sooth, any soldier who sees us would smile that we should creep for three days along this road as though a thousand dangers lay before us, when we have but poor broken peasants to deal with."

But Robert Knolles shook his head. "We know not what are in these woods, or behind these hills," said he, "and when I know nothing it is my wont to prepare for the worst which may befall. It is but prudence so to do."
