Then the evening was spent in merry cheer; but that night Elaine slept but lightly, for her slumber was full of dreams of Lancelot, and her heart burned with fears that he might come to harm in the lists.
On the next day King Arthur and his knights set out for Camelot. Soon afterwards Lancelot and Lavaine took leave of Sir Bernard and his fair daughter, while the eyes of Elaine followed the noble form of Lancelot fondly and far, as he rode. Both the knights had white shields, and Lancelot bore with him Elaine's red embroidered sleeve. When they reached Camelot they took lodging privately with a rich burgess of the town, that none might know them.
When came Assumption Day, the lists were set, the trumpets blew to the field, the two parties of knights gathered promptly to the fray, and fierce was the encounter between them. In the end, after hard fighting, the party of Arthur bore back their opponents, who were headed by the kings of Northumberland and North Wales.
All this was seen by Lancelot and Lavaine, who sat their horses at a distance looking on.
"Come," said Lancelot, "let us help these good fellows, who seem to be overpowered."
"Lead on," said Lavaine. "I shall follow and do my best."
Then Lancelot, with the red sleeve fastened upon his helmet, rode into the thickest of the press, and smote down such numbers of knights with spear and sword that the party of the Round Table were forced to give back, and their opponents came on with fresh heart. And close upon Lancelot's track Lavaine smote down several good knights.
"Who can this wonderful fighter be?" asked Gawaine of the king.
"I know him well," said Arthur, "but will not name him since he is in disguise."
"I could believe it was Lancelot," said Gawaine, "but for that red sleeve. No man ever saw Lancelot wear a woman's token."
