The trumpets blared again, da-DAAA da-DAAA da-DA da-DA da-DAAAAAAA. Sir Gregor waved his huge sword and bellowed a command, and a thousand other voices screamed back at him. Tyrion put his spurs to his horse and added one more voice to the cacophony, and the van surged forward. "The river!" he shouted at his clansmen as they rode. "Remember, hew to the river." He was still leading when they broke a canter, until Chella gave a bloodcurdling shriek and galloped past him, and Shagga howled and followed. The clansmen charged after them, leaving Tyrion in their dust.
A crescent of enemy spearmen had formed ahead, a double hedgehog bristling with steel, waiting behind tall oaken shields marked with the sunburst of Karstark. Gregor Clegane was the first to reach them, leading a wedge of armored veterans. Half the horses shied at the last second, breaking their charge before the row of spears. The others died, sharp steel points ripping through their chests. Tyrion saw a dozen men go down. The Mountain's stallion reared, lashing out with iron-shod hooves as a barbed spearhead raked across his neck.
