They had, so it seemed to them, but barely fallen asleep, when there was great outcry from both within and without the gates. The men of King Mark had evidently decided on a determined attack with full intention to overcome the stubborn few. In a great mass they came and though many fell and every arrow told yet were they not to be denied. And as they came close to the walls King Mark's men opened wide their ranks and a score of men were seen carrying a bridge to throw over in place of the drawbridge which they could not reach.

"Now has it grown right serious," said Sir Launcelot.

"Will you Percival hold these walls while Tristram, I, Gouvernail and Walker, make every effort to see that the bridge does not stay."

There was no time for further words. The four quickly made for the gates. They opened and closed them quickly. Each held a stave that seemed not unlike a young tree, of which a number were inside the gates.

"Let them place the bridge first," said Sir Launcelot.

Upon them a hail of arrows fell but none were hurt. Gouvernail and Walker were protected for the time in both coats and helmets of steel which Sir Tristram had made them wear.

Now the men of King Mark had thrown the bridge over the embankment. But as the first of them rushed upon it the thick staves of the four men did their work well. Mighty work it was but it was question whether there were four men in all of England who had greater strength than these. And so as the men came rushing over, the bridge seemed moving with them.

A great outcry came from them. The new made bridge, moving slowly at first, now cleared its support, and fell into the depths below carrying twenty men with it. Some managed to get back to safety, some, almost as unfortunate as those who had fallen with the bridge, made their way to the castleside. These Sir Tristram and Sir Launcelot and the two yeomen easily overcame.

From the walls a hail of arrows, stones and javelins were sent on the attackers. The four outside the walls, their work accomplished, returned within. But King Mark and his two lieutenants, of whom one had been on the bridge, were now not the less determined to carry the walls.

The besiegers at the furthermost points were seen to clamber over the walls. They were battering at the gates at which Sir Tristram, Sir Launcelot and a number of the men had taken their stand.
