On 22 February 1934, he was promoted to lieutenant with seniority from 1 January 1934. Two years later, he was transferred to the 77th Infantry Regiment in Lida. In 1938, he became the commander of a machine gun company.[3]
World War II
During the 1939 invasion of Poland, Wysocki fought in the ranks of his regiment at Piotrków Trybunalski. After the fighting ended, he returned to Bielsko. In December 1939, following the Soviet invasion of Poland, he was arrested by the Soviet authorities and placed in an internment camp in USSR.[4]
In the second half of 1943, the 1st Infantry Division moved to the front line, becoming part of the 33rd Army of Western Front. On 12 October 1943, the unit went through its baptism of fire in the Battle of Lenino.[5]
On 12 October 1943, Wysocki assumed command of the 3rd Battalion of 1st Infantry Regiment after its commander had been killed in action. Wysocki led his unit in successfully capturing German positions, capturing the enemy's first line of defense, and wedging into the second one at the village of Trigubovo (now: Kostyushkovo). He was killed leading his soldiers in a bayonet attack, while defending his unit's position in Trigubovo.[6]
By the decree of the Presidium of the Supreme Soviet of the USSR of 11 November 1943, Wysocki was posthumously awarded the title of Hero of the Soviet Union for the exemplary performance of combat missions on the front in fight against the German invaders, and for the courage and heroism shown at the same time.[5]
