So, the young Andrey Vasilenko got into the Kyiv Artillery School. He studied there for a while and was redistributed to an artillery unit in Kamianets-Podilskyi.
With his artillery regiment, Andrei Vasilenko fought almost all over Ukraine. Andrey Vasilenko himself was seriously wounded in those battles. When he was in the hospital, he drew his colleagues, and his comrades sent the drawings to their relatives. Many families keep these hand-drawn memos made by Andrey Stepanovich.
