He was interned in August 1917 after the majority of his unit had refused to pledge loyalty to the Emperor of Austria.

In February 1918, he was released from the internment camp in Beniaminów and joined the Polska Siła Zbrojna.

From June 1939, Rowecki organised the Warsaw Armoured Motorized Brigade (Warszawska Brygada Pancerno-Motorowa, 7TP, TKS tanks).

In 1941, Rowecki organized sabotage in the territories east of the Polish pre-war borders Wachlarz.

In February 1943, he ordered the Home Army to help the Jewish underground seeking to mount ghetto uprisings.

Rowecki was arrested due to his betrayal by Ludwik Kalkstein "Hanka", Eugeniusz Świerczewski "Genes" and Blanka Kaczorowska "Sroka" who were Gestapo agents.

The sentence on Eugeniusz Swierczewski was carried out by troops commanded by Stefan Rys ("Jozef").

After the war, he worked for the Polish Radio station in Szczecin and was later recruited as an agent by the Urząd Bezpieczeństwa.

During the same period, the Gestapo arrested the commander of National Armed Forces (NSZ), Colonel Ignacy Oziewicz on 9 June 1943.
