But yet he was only safe for a little while, for about the time of early nightfall, which came not long thereafter, a great party of several score of King Mark’s people came against the chapel where he was.  And when they found that the doors were locked and barred, they brought rams for to batter in the chief door of the chapel.

Then Sir Tristram beheld how parlous was his case, and that he must in a little while die if he did not immediately do something to save himself.  So with that he ran to a window of the chapel and opened it and looked out thence.  And lo! below him and far beneath was the sea, and the rocks of the shore upon which the castle was built; and the sea and the rocks lay twelve fathoms beneath him.

[Sidenote:  Sir Tristram leaps into the sea] But Sir Tristram said, “Better death there than here;” and therewith finding that the door was now falling in beneath the rams, he leaped out from the window-ledge, and thence he dived down into the sea; and no one saw that terrible leap that he made.  So he sank down deep into the sea, but met no rocks, so that he presently came up again safe and sound.  Then, looking about him, he perceived in the twilight a cave in the rocks, and thither he swam with the intent to find shelter for a little.

Now when they who had come against him had broken into the chapel they all ran in in one great crowd, for they expected to find Sir Tristram and to do battle with him.  But lo!  Sir Tristram was not there, but only the empty walls.  Then at first they were greatly astonished, and knew not what to think.  And some who came cried out:  “Is that man then a spirit that he can melt away into thin air?” But after a little, one of them perceived where the window of the chapel stood open, and therewith several of them ran thereunto and looked out, and they wist that Sir Tristram had leaped out thence into the sea.

Then they said to one another:  “Either that knight is now dead, or else he will perish when the tide rises and covers the rocks; so to-night we will do no more with this business; but to-morrow we will go and find his body where it lies among the rocks of the shore.”  So thereupon they shut the window and went their ways.

Now Gouvernail was not at that time at Tintagel, nor did he return thereunto until all this affair was over and done.  But when he came there, there were many voices to tell him what had befallen, and to all of them Gouvernail listened without saying anything.

But afterward Gouvernail went and sought out a certain knight hight Sir Santraille de Lushon, who, next to himself, was the most faithful friend to Sir Tristram at that place.  To him Gouvernail said:  “Messire, I do not think that Sir Tristram is dead, for he hath always been a most wonderful swimmer and diver.  But if he be alive, and we do not save him, he will assuredly perish when the tide comes up and covers over those rocks amongst which he may now be hidden.”
