Szare Szeregi
Romocki was active in the Szare Szeregi (Gray Ranks) organisation from 1940 onwards and during the Warsaw Uprising he was the commander of the Rudy Company of the AK Zośka Battalion. He took command of the whole battalion on 31 August 1944 until his death in the Czerniaków district on 15 September. It's possible that he was killed as a result of "friendly fire" by soldiers of the Ludowe Wojsko Polskie (LWP, People's Army of Poland).
