Гонорий III
Valdemar immediately appealed to Pope Honorius III to have his oath declared void, a request granted by the Pope. Honorius III excused Valdemar from his forced oath, and he immediately set about trying to restore the German territories. Valdemar concluded a treaty with his nephew Otto I, Duke of Brunswick-Lüneburg and headed south to take back what he thought were his lands by right, but his luck deserted him. A series of Danish defeats culminating in the Battle of Bornhöved on 22 July 1227 cemented the loss of Denmark's north German territories. Valdemar himself was saved only by the chivalrous acts of a German knight who carried Valdemar to safety on his horse.
