1514 Count
John V of Oldenburg saw this as an opportunity to provide the
county of Oldenburg with access to the
North Sea. In 1514, he attacked the Frisians in the
Butjadingen area, and finally defeated them in the Battle of Langwarden. Simultaneously, Duke
Henry I of Brunswick-Wolfenbüttel invaded East Frisia with an army of 20,000 men. He besieged
Fortress Leerort, which was only defended by a few peasants and soldiers. However, Henry I was killed on 23 June 1514 by a targeted gunshot. His troops were then without a leader and they withdrew from East Frisia. John V, in cooperation with
Hero Oomkens von Esens, captured the castle at
Großsander. Hero moved on and destroyed all three castles in
Dornum;
Stickhausen Castle was thus lost. Edzard retreated, setting
Meerhusen Abbey on fire to cover his retreat. The city of
Aurich was besieged and destroyed by the fighting and pillaging troops. On another front, the
Commandery at Dünebroek was plundered by soldiers of the
Black Guard. They went on to destroy Burmönken,
Marienhafe,
Leerhafe, and
Rispel;
Friedeburg surrendered. The castle at Altgödens was destroyed;
Kniphausen Castle was captured. The Black Guard then attacked
Oldersum. Their first attempt to capture the town, which was defended by
Hicko of Oldersum and
Ulrich of Dornum failed on 14 June 1514. A second attempt to capture the town failed on 16 August 1514.
1515-1516 In 1515, the tide turned in favor of Edzard I. He recaptured the castle at
Großsander, while his liegeman Fulf of Kniphausen managed to capture Fortress Gutzwarden in Butjadingen. Duke George of Saxony sold his governorship for to Duke Charles of Burgundy, who later became Emperor as
Charles V. Nevertheless, the conflict continued until 1517. The
sconce at
Detern was lost in 1516.
1517 At the beginning of 1517, Edzard I managed to recapture
Friedeburg castle. Charles V began his reign in the Netherlands. Charles V lifted the Imperial ban against Edzard and invested him with East Frisia, thereby ending the Saxon feud. == Aftermath ==
