Baldwin I of Jerusalem of his blood", according to Albert of Aix, a contemporary historian of the First Crusade. Warner of Grez, Godfrey's most influential retainer took possession the Tower of David in Jerusalem to secure control of the town. Although Walter soon died, Geldemar Carpenel and Arnulf of Chocques sent a delegation to Baldwin, urging him to come to Jerusalem. To prevent Baldwin from seizing Godfrey's realm, Daimbert and Tancred sought assistance from Bohemond I of Antioch. Daimbert sent a letter to him, stating that Baldwin's rule would "bring about the downfall of the church and the destruction of Christianity itself", according to
Baldwin I, Latin Emperor trying to seduce Kaloyan's wife. The historian George Acropolites reports that the Tsar had Baldwin's skull made into a drinking cup, just as had happened to Nicephorus I almost four hundred years before. Tsar Kaloyan wrote to Pope Innocent III, reporting that Baldwin had died in prison. A tower of the Tsarevets fortress of the medieval Bulgarian capital, Veliko Tarnovo, is still called Baldwin's Tower; supposedly, it was the tower where he was interned. It was not until July 1206 that the Latins in Constantinople had reliable information that Baldwin was dead. His brother Henry was crowned emperor in August.
