The others made ready to joust likewise, all five lowering their lances and letting their horses go. Perceval spurred his own, and met the first with a blow that smashed through his shield, through the folds of his mail, through his heart and struck him dead. Now he engaged the others: they delivered mighty blows to his shield that pierced and smashed it and rent his hauberk, wounding him a little in the belly; but they couldn’t unhorse him – instead all four of their lances broke, so they drew their swords, sharp and honed.
