I want to know the answer to the following question:
What is date of the Battle of Swienta?
All the background I'm provided with is that "After the decline of the Teutonic Order following its defeat in the Battle of Grunwald in 1410, and the defeat of the Livonian Order in the Battle of Swienta on 1 September 1435, the Livonian Confederation Agreement was signed on 4 December 1435.". Is that enough to answer the question?
