The battle of Agincourt was almost over when Henry V ordered the prisoners killed. Nowadays, this would clearly be a war crime, but in 1415, it wasn’t, though nobody liked it. Henry did not expect to win the battle, which involved a fairly small bunch of muddy unarmored Englishmen with dysentery up against a formidable line of armored Frenchmen on horses. So he didn’t know, when a group of Frenchmen at the rear of their forces attempted to regroup, that they were going nowhere and were not an issue. He thought they were, and that then the Frenchmen at the rear of the English, the war prisoners, would be able to break through, pick up arms from the battlefield, and slaughter the English. The English were all assuming that none of them were going home, but they were fighting as best they could. But as it happens the battle was almost over anyway, and the English won — they had lost a few hundred men; the French had lost several thousands. Anne is extremely happy, because she gets to talk about the Welsh longbowmen, and Michelle is extremely happy because she gets to tell you where the people of Normandy were hiding whilst Henry and his army roamed around, and believe me, you will not be able to guess where they were. Unless you already have inside knowledge.
