i mua i tana tūao mo te mahi i roto i te Pakanga Tiamana-Rāhui. I te timatanga i mahi ia i te Wahanga 4 o te Leningrad People's Militia i mua i tana urunga ki tetahi roopu hauora, ahakoa he pakeke rawa ia ki te whakauruhia. I te marama o Noema 1941 i tukuna ia ki te whawhai hei sniper i roto i te 1st Infantry Battalion o te 284th Infantry Regiment o te 86th Tartu Rifle Division, i reira ia i eke ai i nga rarangi ki te kaitiaki-nui (starshina). I roto i te Pakanga o Leningrad i whakangungu ia i etahi atu hoia o te ope Whero hei kaipatu, hei taapiri ki te uru atu ki te whawhai tuuturu.
