Born in 1892, Bäßler joined the army of Imperial Germany in early 1914 and was commissioned a leutnant in the infantry. He participated in World War I and afterwards was among the personnel retained in the postwar Reichswehr. By 1935, he was the Chief of Operations, or 1a, of the 1st Panzer Division. Promoted to oberst, from 1938 to 1939, he commanded the 4th Panzer Regiment, which was part of the 2nd Panzer Division. Upon the outbreak of World War II, Bäßler was serving as Chief of Staff of XI Army Corps and participated in the Invasion of Poland in this capacity. He remained on the staff of XI Corps through the Battle of France, the Invasion of Yugoslavia, and Operation Barbarossa, the latter as part of Army Group South, until February 1942. In April 1942, and now a generalmajor, he was given command of 9th Panzer Division which was then operating on the Eastern Front, around the town of Shchtschigry, to the east of Kursk. In July 1942 the division was involved in heavy fighting to secure the German northern flank around Zemlyansk, northwest of Voronezh, when Bäßler was seriously wounded and had to leave his command on 27 July 1942. Following recuperation from his wounds, on 16 November 1942, Bäßler took command of 14th Panzer Division which, at the time, was engaged in the Battle of Stalingrad. He led the division until 26 November 1942 at which time he was again wounded and evacuated from the city. He thus avoided capture when the Germans surrendered the city in early 1943. Bäßler returned to active duty in July 1943 when he was appointed commander of the newly formed 242nd Infantry Division. His new command was initially based in northeastern Germany before being transferred to Liege in Belgium for training and occupation duties. In October 1943, the division, intended to be a static unit with little organic transport, was moved to the south of France and the following February, Bäßler was promoted to generalleutnant. The day after the launch of Operation Dragoon, the Allied invasion of Southern France in mid-August 1944, Bäßler and his division were ordered to hold the city ofToulon. The division resisted the french forces in the Battle of Toulon for ten days before Bäßler, who had been critically wounded, surrendered it on 26 August 1944. Although initially made a prisoner of war, he was repatriated to Germany shortly after his capture. He died of his wounds in a hospital in Vienna on 27 November 1944.
