Thus by treachery, and through the ambition of a weak King, Arthur’s last war began.

We were ready for that war. We had expected the attack to come weeks before, and though Mordred’s timing surprised us our plans were all made. We would sail south across the Severn Sea and march to Durnovaria where we expected Sagramor’s men to join us. Then, with our forces united, we would follow Arthur’s bear north to confront Mordred as he returned from Siluria. We expected a battle, we expected to win, and afterwards we would acclaim Gwydre as King of Dumnonia on Caer Cadarn. It was the old story; one more battle, then everything would change.

Messengers were sent to the coast demanding that every Silurian fishing-boat be brought to Isca, and while those boats rowed up river on the flood tide, we readied for our hasty departure. Swords and spears were sharpened, armour was polished and food was put into baskets or sacks. We packed the treasures from the three palaces and the coins from the treasury, and warned Isca’s inhabitants to be ready to flee westwards before Mordred’s men arrived.

Next morning we had twenty-seven fishing-boats moored in the river beneath Isca’s Roman bridge. A hundred and sixty-three spearmen were ready to embark, and most of those spearmen had families, but there was room in the boats for them all. We were forced to leave our horses behind, for Arthur had discovered that horses make bad sailors. While I had been travelling to meet Nimue he had tried loading horses onto one of the fishing-boats, but the animals panicked in even the gentlest waves, and one had even kicked its way through the boat’s hull and so on the day before we sailed we drove the animals to pastures on a distant farm and promised ourselves we would return for them once Gwydre was made King. Morgan alone refused to sail with us, but instead went to join her husband in Gwent.

We began loading the boats at dawn. First we placed the gold in the bottom of the boats, and on top of the gold we piled our armour and our food, and then, under a grey sky and in a brisk wind, we began to embark. Most of the boats took ten or eleven people, and once the boats were filled they pulled into the middle of the river and anchored there so that the whole fleet could leave together.
