Niemen
a river of Russia, whose lower course (70 of its 500 miles) lies within the province of East Prussia, where it is called the Memel; it rises a few miles S. of the city of Minsk. It is navigable to Grodno; below Tilsit it divides into two branches, which reach the Kurisches Haff each by four mouths.
Along a large part of its course some of the most severe fighting between the German and Russian armies took place during the World War.
