Ypres had a numerous garrison, commanded by several knights of experience. The works were very strong, and every assault was repulsed with heavy loss. One of these was led by Sir Hugh Calverley. The force crossed the ditches by throwing in great bundles of wood with which each of the foot-men had been provided, and having reached the wall, in spite of a hail of cross-bow bolts and arrows, ladders were planted, and the leaders endeavoured to gain the ramparts. Sir Hugh Calverley succeeded in obtaining a footing, but for a time he stood almost alone. Two or three other knights, however, sprang up. Just as they did so one of the ladders broke with the weight upon it, throwing all heavily to the ground.

Edgar and Albert were with a party of archers who were keeping up a rain of arrows. Seeing that the situation was bad they now ran forward, followed by four of their men-at-arms, the others having charge of the horses in the camp. A few more men-at-arms had gained the ramparts by the time they arrived at the foot of the ladders, where numbers waited to take their turns to ascend.

"There is not much broken off this one, Sir Edgar," Hal Carter said; "not above three feet, I should say. We might make a shift to get up with that."

"Pick it up, Hal, and bring it along a short distance. Possibly we may be able to mount unobserved, for the fight is hot above, and the attention of the enemy will be fixed there."

Followed by their own men-at-arms, and by a few others who saw what their intentions were, they kept along at the foot of the wall until they reached an angle some thirty yards away. Searching about they found several stones that had been dislodged from the battlements during the siege. With these they built up a platform, and raising the ladder on this, they found that it reached to within a foot of the top.

"Now," Edgar said, "follow us as quickly as you can, but do not try the ladder too heavily; it has broken once, so the wood cannot be over-strong."

Then, followed closely by Albert and the men-at-arms, he ascended the walls. So intent were the defenders upon the strife going on round Sir Hugh Calverley that Edgar was not noticed until, putting his hands upon the wall, he vaulted over it. He held his sword between his teeth, and betaking himself to this fell so fiercely and suddenly upon the enemy, that several were cut down and the rest recoiled so far that Albert and the four men-at-arms were able to join him before the enemy rallied. Every moment added to the strength of the party, and as soon as some twenty had gathered behind him, Edgar flung himself upon the enemy with a shout of "St. George! St. George!" and, in spite of the opposition of the defenders, fought his way along the wall until he joined Sir Hugh and the little group who were defending themselves against tremendous odds.

Sir Hugh himself was seriously wounded. Two or three of his knights lay dead beside him, and had it not been for the arrival of the reinforcement the fight would speedily have terminated, for the English were so penned up against the wall that there was no footing for more to join them. The suddenness of the attack drove the enemy back some little distance, and this enabled a score of those upon the ladders to make their way onto the rampart.

"Bravely done!" Sir Hugh Calverley said, as he leant against the wall, utterly exhausted by his efforts and loss of blood. A moment later he would have fallen had not Albert sprung to his side.

"We must save Sir Hugh at all risks," he said to two of the knight's companions, who were also wounded. "Will you, sir knights, aid in lowering him down the ladder, and see that he is carried off? You have done your share. It is our turn now, and we can at least hold the rampart until he is in safety."
