Then he departed and rode to the sea, and on the strand he found a ship all covered with white samite, and as soon as he had entered thereinto, it put forth from the shore. And in the midst of the ship there stood an armed knight, whom he knew to be Sir Percival. Then they rejoiced greatly over each other, and said, "We lack nothing now but the good knight Sir Galahad."
Now when Sir Galahad had rescued Sir Percival from the twenty knights he rode into a vast forest. And after many days it befell that he came to a castle whereat was a tournament. And the knights of the castle were put to the worse; which when he saw, he set his spear in rest and ran to help them, and smote down many of their adversaries. And as it chanced, Sir Gawain was amongst the stranger knights, and when he saw the white shield with the red cross, he knew it was Sir Galahad, and proffered to joust with him. So they encountered, and having broken their spears, they drew their swords, and Sir Galahad smote Sir Gawain so sorely on the helm that he clove it through, and struck on slanting to the earth, carving the horse's shoulder in twain, and Sir Gawain fell to the earth. Then Sir Galahad beat back all who warred against the castle, yet would he not wait for thanks, but rode away that no man might know him.
And he rested that night at a hermitage, and when he was asleep, he heard a knocking at the door. So he rose, and found a damsel there, who said, "Sir Galahad, I will that ye arm you, and mount upon your horse and follow me, for I will show you within these three days the highest adventure that ever any knight saw."
Anon Sir Galahad armed him, and took his horse, and commended himself to God, and bade the gentlewoman go, and he would follow where she liked.
So they rode onwards to the sea as fast as their horses might gallop, and at night they came to a castle in a valley, inclosed by running water, and by strong and high walls, whereinto they entered and had great cheer, for the lady of the castle was the damsel's mistress.
And when he was unarmed, the damsel said to her lady, "Madam, shall we abide here this night?"
"Nay," said she, "but only till he hath dined and slept a little."
So he ate and slept a while, till the maid called him, and armed him by torchlight; and when he had saluted the lady of the castle, the damsel and Sir Galahad rode on.
Anon they came to the seaside, and lo! the ship, wherein were Sir Percival and Sir Bors, abode by the shore. Then they cried, "Welcome, Sir Galahad, for we have awaited thee long."
Then they rejoiced to see each other, and told of all their adventures and temptations. And the damsel went into the ship with them, and spake to Sir Percival: "Sir Percival, know ye not who I am?"
