Henry advised them to flee to Scotland and they subsequentlytook refuge in de Morville's Knaresborough Castle in NorthYorkshire. It is known that Hugh de Morville, Richard de Breton,and William de Tracy built a church at Alkborough, near Scunthorpein South Humberside, where, until 1690, an inscribed stone on thechancel recorded the benefaction.Despite their benefactions they failed to impress Pope AlexanderIII, and he excommunicated them on Maundy Thursday, 25 March1171.The Archbishop's murderers finally gained their audience withthe Pope, who, despite their penitence declared they should beexiled and fight in knightly arms in The Temple for 14 years inJerusalem, and after the given time return to Rome.A Hugh de Morville appears in the service of the Crusader-kingRichard I in the 1190s. It seems probable that this individual isone and the same. He stood hostage for Richard in 1194, when theking had been captured by Henry VI, Holy Roman Emperor. As to theother three, there are various stories but no actual proof of whathappened to them.
