Then spake all at once seven brethren of North Wales,--and they were seven noble knights, a man might seek in seven lands ere he might find such seven knights: "Sir Launcelot, let us ride out with Sir Galihud, for we be never wont to cower in castle, or in noble towns."
But then spake Sir Launcelot, that was master and governor of them all: "My fair lords, wit ye well I am full loath to ride out with my knights, for shedding of Christian blood; and yet my lands I understand to be full bare to sustain any host a while, for the mighty wars that whilom made King Claudas upon this country, upon my father King Ban and on mine uncle King Bors. Howbeit we will at this time keep our strong walls, and I shall send a messenger unto my lord Arthur, a treaty for to take, for better is peace than always war."
So he sent forth a damsel, and a dwarf with her, requiring King Arthur to leave his warring upon his lands. When she came to the pavilion of King Arthur there met her a gentle knight, Sir Lucan the butler, and when he knew that she was a messenger from Sir Launcelot to the King he said: "I pray God, damsel, ye may speed well. My Lord Arthur would love Launcelot, but Sir Gawaine will not suffer him."
So Lucan led the damsel unto the King, and when she had told her tale, all the lords were full glad to advise him to be accorded with Sir Launcelot, save only Sir Gawaine, who would not turn again, now that they were past thus far upon the journey.
"Wit ye well, Sir Gawaine," said Arthur, "I will do as ye will advise me; and yet me seemeth his fair proffers were not good to be refused."
Then Sir Gawaine sent the damsel away with the answer that it was now too late for peace. And so the war went on. Sir Launcelot was never so loath to do battle, but he must needs defend himself; and when King Arthur's host besieged Benwick round about, and fast began to set up ladders, then Sir Launcelot beat them from the walls mightily.
Then upon a day it befell that Sir Gawaine came before the gates fully armed on a noble horse, with a great spear in his hand, and cried with a loud voice: "Where art thou now, thou false traitor, Launcelot? Why hidest thou thyself within holes and walls like a coward? Look out now, thou false traitor knight, and here I shall revenge upon thy body the death of my three brethren."
