Whakaotihia te rerenga e whai ake nei: I te tau 1914, i uru ia ki te roopu pupuhi o te Polish Legion, a ka tohaina tana whare rangatira i Zembrzyce mo te whakaora i nga hoia i whara. I tenei wa i tangohia ai e ia a "Zyndram" (kōrere) hei ingoa tuarua. I whawhai ia i raro i te whakahau a Kapene Zbigniew Dunin-Wasowicz, katahi ka mahi ia i te tari matua mo te Polish Legion. I te tau 1915, i whakawhitihia ia ki te whakahau a te Kawana-Karauna, a Edward Rydz-Śmigły; i uru ki nga pakanga o
Jastków, Kostiuchnówka, me ētahi atu. I te tau 1916, i mate ia ki te typhus. Ahakoa i ora ia, ka mutu tana whai waahi kaha ki te pakanga, no reira, i te tau 1917, ka hoki ia ki Kraków ka uru ki te whakarite i te whare taonga hoia. I whakatairangahia ia ki te rangatira i te 1918, i mahi ia i te tari whakatairanga o te 2nd Rifle Division, me te korero i te Military Geographical Institute. I mahi ia tae noa ki te 1922, i te wa i whakawhitihia ai ia ki nga rahui.
