After the withdrawal of the Polish–Lithuanian forces, the Knights started taking back their fortresses. By the end of October, only four Teutonic castles remained in Polish hands – border towns of Thorn (Toruń), Nessau (Nieszawa), Rehden (Radzyń Chełmiński) and Strasburg (Brodnica). Jogaila raised a fresh army and dealt another defeat to the Knights in the Battle of Koronowo on 10 October 1410. Von Plauen, using his reputation as hero of Marienburg, was selected as the new Grand Master in November. Von Plauen wanted to continue warfare, but he was pressured by his advisers into peace negotiations. The Peace of Thorn was signed on 1 February 1411. It is considered a diplomatic victory for the Knights as they suffered only minimal territorial losses. The Siege of Marienburg and subsequent Peace of Thorn are seen as disappointing results of the great Battle of Grunwald.
