On 16 July 1384 Vytautas re-confirmed the Treaty of Königsberg in New Marienverder, a new fortress built on the Neman River. However, the treaty was broken in July when Vytautas and Jogaila reconciled. Vytautas burned Teutonic castles and returned to Lithuania. During the Lithuanian Civil War (1389–1392) Vytautas once again asked for military support from the Knights. On 19 January 1390 he signed the Treaty of Lyck, confirming the Treaty of Königsberg only to break it again in 1392. Vytautas granted Samogitia to the Knights two more times: by Treaty of Salynas (1398) and by Treaty of Raciąż (1404).
