Walter was furious when he heard the contents of this letter, and the king and Black Prince were no less indignant. Although they doubted him not for a moment, Walter begged that Ralph might be brought before them and examined strictly as to what had taken place, in order that they might see that his statements tallied exactly with those he had made. When this had been done Walter obtained permission from the king to dispatch a cartel to Sir Philip de Holbeaut denouncing him as a perjured and dishonored knight and challenging him to meet him in mortal conflict at any time and place that he might name. At the same time the king dispatched a letter to Philip of Valois saying that the statements of the French knight and his followers were wholly untrue, and begging that a time might be appointed for the meeting of the two knights in the lists. To this King Philip replied that he had ordered all private quarrels in France to be laid aside during the progress of the war, and that so long as an English foot remained upon French soil he would give no countenance to his knights throwing away the lives which they owed to France in private broils. "You must wait, Sir Walter, you see," the king said, "until you may perchance meet him in the field of battle. In the mean time, to show how lightly I esteem the foul charge brought against you, and how much I hold and honor the bravery which you showed in defending the castle which my son the prince intrusted to you, as well as upon other occasions, I hereby promote you to the rank of knight banneret." Events now passed slowly before Calais. Queen Philippa and many of her ladies crossed the Channel and joined her husband, and these added much to the gayety of the life in camp. The garrison at Calais was, it was known, in the sorest straits for the want of food, and at last the news came that the King of France, with a huge army of two hundred thousand men, was moving to its relief. They had gathered at Hesdin, at which rendezvous the king had arrived in the early part of April; but it was not until the 27th of July that the whole army was collected, and marching by slow steps advanced toward the English position. King Edward had taken every precaution to guard all the approaches to the city. The ground was in most places too soft and sandy to admit of the construction of defensive works; but the fleet was drawn up close inshore to cover the line of sand-hills by the sea with arrows and war machines, while the passages of the marshes, which extended for a considerable distance round the town, were guarded by the Earl of Lancaster and a body of chosen troops, while the other approaches to the city were covered by the English camp.
