The Battle of Krasny Bor took place in northern Russia, near the village of Krasny Bor during World War II and was fought between the German Army’s 250th Infantry Division, which consisted of Spanish volunteers, and the Soviet 55th Army, from February 10 to February 13, 1943, with the major clash taking place on February 10, 1943. This military operation ended with a few miles of the Leningrad–Moscow Highway in Soviet hands for the first time since September 1941, but the Spanish division was able to hold off the much larger Soviet forces without yielding substantial ground.
