History / An Israeli Song that its origin is Polish - Please, help to identify it! [4]

There is an Israeli/ Hebrew old song that you can listen to in this link: youtube.com/watch?v=HFwnhKPO9DU . There is an evidence that its origin is either Polish or Ukrainian. There is even evidence about some words of its origin - in Polish: W pustym stepie na kurhanie młody ułan pada. Maybe the words are not exact, but the songs tells about a horseman who is about to die and asking his horse to run to his mother who is wating to him far away from him and tell her about it (Some Ukrainian words: Przez/ Крізь/ Через курганы козак молоденький: ... Гину,гину... Гину,гину..). I will highly appreciate your kind efforts to identify this song - the accurate text, the names of its authors (of the text and composer) and the most important - a performance of the song in Polish andq or Ukrainian.
