During the siege of Weißensee on 17 September 1204, Landgrave Hermann of Thuringia humbly submitted to the Hohenstaufen. It is the only case of submission ("deditio") through which the historical sources provide detailed information. According to chronicler Arnold of Lübeck, Philip held up to the Landgrave "while he was lying on the ground for so long" about his "disloyalty and stupidity". Only after the intercession of those present was he lifted from the floor and received the peace kiss from the King. Hermann had initially supported Otto, switched to Philipp in 1199 and then again joined Otto in 1203/04. The Landgrave was able to retain his title and property after his submission and stayed in the Hohenstaufen side until Philip was murdered.
