One of the first stories included in the History of William Marshal goes back to the reign of King Stephen (1135-1154), which was marred by a civil war with Empress Matilda. William’s father, John Marshal, originally supported Stephen and was a close advisor, but then after a few years he switched sides. In 1152, Stephen was besieging John at Newbury Castle, when the two sides agreed on a truce. The English king demanded that John send him a hostage to secure his promise that he would surrender the castle, and the nobleman sent his fourth son, William, to the enemy camp.

However, it soon became clear that Newbury Castle would not be surrendered. What would now become of the young boy? King Stephen could have him executed, and threats that would happen were sent to John. According to the History of William Marshal:

Word came of this to his father, but he said that he did not care about the child, since he still had the anvils and hammers to produce even finer ones.

This callous remark spurred the besiegers to bring William next to the castle, where they prepared to execute him. As they did so the young boy, ignorant of what was happening, asked to play with the Earl of Arundel’s javelin. The King could not continue with the pretence of an execution, telling William, “I’ll spare you this torture, you can be sure you won’t die here now.”

However, the King’s supporters convinced him to have the boy put into a type of trebuchet, so he could be catapulted against the castle’s walls. The History of William Marshal states:

The child, too young to have much understanding of events, was led away towards the catapult. When he saw the catapult’s sling, he took a step back, and said, “Gracious me! What a swing! It would be a good idea for me to have a swing on it.” He went right up to the sling

For a second time, Stephen decided he could not go through with it. He shouted, “Take him away! Take him away! Anyone who could allow him to die in such agony would certainly have a very cruel heart.”

The scene plays out again a third time – here William was placed hanging over a siege machine and brought back to the castle. One of Stephen’s men shouted to John Marshall, “Lord constable, show yourself. Here’s your lord’s son; he’s going to die now in great pain, because we’re going to put him on that frame.”

“Is that a promise?” John asked. When they replied yes, the father replied, “Right then, so he’ll die, I swear! I’ll tell you this: the only present he’ll get is to be squashed to a pulp like a drum skin. This trick of yours won’t get you anywhere, you’re going to see him die right now.”

John then had his troops hurl down a large millstone at the besiegers. Little William, still hanging there asked what kind of toy this was. Again, this broke the will of King Stephen, who burst out laughing and said, “William, a toy like that would be no good at all for you. To do you any harm would be a great shame because you haven’t done anything wrong. I shall spare you toys such as this, you’ll never die at my hands.”

After this third attempt, King Stephen took William back to his own tent and made sure he would not be harmed. The History of William Marshal adds that they even played a game, in which the boy collected flowers and they played ‘knights’ with them – somehow William always won. Eventually he was returned back to his father.

Historians have wondered about the episode, even questioning if it really happened (no other source but the History of William Marshal records it). Most have concluded that even if the story has some embellishments, because it was based on a tale told by William himself, it was for the most part true.
