‘Oars!’ Balig called, but no one heeded him. We were too busy pushing the swimmers away from the hull. I worked one-handed, thrusting attackers under the water, but one madman seized my spear shaft and almost pulled me into the water. I let him have the weapon, drew Hywelbane and sliced her down. The first blood flowed on the river.
The river’s north bank was now thick with Nimue’s howling, capering followers. Some threw spears at us, but most just screamed their hate, while others followed the swimmers into the river. A long-haired man with a hare lip tried to climb aboard our bows, but the Saxon kicked him in the face, then kicked him again so that he fell. Taliesin had found a spear and was using its blade on other swimmers. Downstream of us a boat drifted onto the muddy bank where its crew desperately tried to pole themselves free of the mud, but they were too slow and Nimue’s spearmen scrambled aboard. They were led by Bloodshields, and those practised killers screamed defiance as they carried their spears down the stranded boat’s length. It was Bishop Emrys’s boat and I saw the white-haired Bishop parry a spear with a sword, but then he was killed and a score of mad things followed the Bloodshields onto the slippery deck. The Bishop’s wife screamed briefly, then was savaged by a spear. Knives slashed and ripped and stabbed, and blood trickled from the scuppers to flow towards the sea. A man in a deerskin tunic balanced himself on the stern of the captured boat, and, as we drifted past, leapt towards our gunwale. Gwydre raised his spear and the man shrieked as he impaled himself on the long shaft. I remember his hands gripping the spear pole while his body writhed on the point, then Gwydre dropped both spear and man into the river and drew his sword. His mother was thrusting a spear into the thrashing arms beside the boat. Hands clung to our gunwale and we stamped on them, or cut them with swords, and gradually our boat drew away from its attackers. All the boats were drifting now, some sideways, some stern first, and the boatmen were swearing and shouting at each other or else screaming at the spearmen to use the oars. A spear flew from the bank and thumped into our hull, and then the first arrows flew. They were hunters’ arrows, and they hummed as they whipped over our heads.
‘Shields!’ Arthur shouted, and we made a wall of shields along the boat’s gunwale. The arrows spat into them. I was crouching beside Balig, protecting both of us, and my shield quivered as the small arrows thumped home.
We were saved by the river’s swift current and by the ebbing tide which carried our jumbled mass of boats downstream and so out of the bowmen’s range. The cheering, raving horde followed us, but west of the amphitheatre there was a stretch of boggy ground and that slowed our pursuers and gave us time in which we could at last make order out of chaos. The cries of our attackers followed us, and their bodies drifted in the current beside our small fleet, but at last we had oars and could pull the boat’s bow around and follow the other vessels towards the sea. Our two banners were stuck thick with arrows.
‘Who are they?’ Arthur demanded, staring back at the horde.
‘Nimue’s army,’ I said bitterly. Thanks to Morgan’s skill, Nimue’s charms had failed and so she had unleashed her followers to fetch Excalibur and Gwydre.
‘Why didn’t we see them coming?’ Arthur wanted to know.
‘A charm of concealment, Lord?’ Taliesin guessed, and I remembered how often Nimue had worked such charms.
Galahad scoffed at the pagan explanation. ‘They marched through the night,’ he suggested, ‘and hid in the woods until they were ready, and we were all too busy to look for them.’
‘The bitch can fight Mordred now instead of us,’ Culhwch suggested.
‘She won’t,’ I said, ‘she’ll join him.’
But Nimue had not finished with us yet. A group of horsemen were galloping on the road that led northwards about the swamp, and a horde of folk followed those spearmen on foot. The river did not run straight to the sea, but made vast loops through the coastal plain and I knew that at every western curve we would find the enemy waiting.
The horsemen did indeed wait for us, but the river widened as it neared the sea and the water ran swiftly, and at each bend we were swept safely past them. The horsemen called curses down on us, then galloped on to find the next bend from where they could launch their spears and arrows at us. Just before the sea there was a long straight stretch of the river and Nimue’s horsemen kept pace with us all down the length of that reach, and that was when I first saw Nimue herself. She rode a white horse, was dressed in a white robe, and had her hair tonsured like a Druid. She carried Merlin’s staff and wore a sword at her side. She shouted at us, but the wind snatched her words away, and then the river curved eastwards and we slid away from her between the reed-thick banks. Nimue turned away and spurred her horse towards the river’s mouth.
‘We’re safe now,’ Arthur said. We could smell the sea, gulls called above us, ahead was the endless sound of waves breaking on a shore, and Balig and the Saxon were hitching the sail’s yard to the ropes that hoisted it up the mast. There was one last great loop of the river to negotiate, one last encounter with Nimue’s horsemen to endure, and then we would be swept out into the Severn Sea.
‘How many men did we lose?’ Arthur wanted to know, and we shouted questions and answers back and forth between the small fleet. Only two men had been struck by arrows, and the one stranded boat had been overwhelmed, but most of his small army was safe. ‘Poor Emrys,’ Arthur said, and then was silent for a while, but he pushed the melancholy aside. ‘In three days,’ he said, ‘we’ll be with Sagramor.’
He had sent messages eastwards and, now that Mordred’s army had left Dumnonia, there was surely nothing to stop Sagramor coming to meet us. ‘We shall have a small army,’ Arthur said, ‘but a good one. Good enough to beat Mordred, and then we start all over again.’
‘Start over again?’ I asked.
‘Beat back Cerdic once more,’ he said, ‘and knock some sense into Meurig.’ He laughed bitterly.
‘There’s always one more battle. Have you noticed that? Whenever you think everything is settled, it all seethes up again.’ He touched Excalibur’s hilt. ‘Poor Hygwydd. I shall miss him.’
‘You’ll miss me too, Lord,’ I said gloomily. The stump of my left wrist was throbbing painfully and my missing hand was unaccountably itching with a sensation so real that I kept trying to scratch it.
‘I’ll miss you?’ Arthur asked, raising an eyebrow.
‘When Sansum summons me.’
‘Ah! The mouse lord.’ He gave me a quick smile. ‘I think our mouse lord will want to come back to Dumnonia, don’t you? I can’t see him gaining preferment in Gwent, they have too many bishops already. No, he’ll want to come back, and poor Morgan will want the shrine at Ynys Wydryn again, so I shall make a bargain with them. Your soul for Gwydre’s permission for them to live in Dumnonia. We’ll free you of the oath, Derfel, never you mind.’ He slapped my shoulder, then clambered forward to where Guinevere sat beneath the mast.
