Many concentration camp prisoners lost their lives on the so-called death marches. The Lithuanian Jew, Isia Rosmarin, who was born in Kaunas on 15 June 1927, found himself on a death march in early May 1945 from Kaufering via Dachau concentration camp heading towards the south.

Just like his fellow prisoners, he was tormented by hunger. He gave the then 14-year boy, Friedrich Kunstwald, who happened to cross his path, the only thing he owned: his accordion. With the plea for some bread.

Friedrich Kunstwald kept his word, and fetched a loaf of potato bread from his mother, which he gave to the prisoners. He shared the bread with his fellow prisoners. Together with them, Isia Rosmarin was liberated shortly afterwards in Waakirchen by US American soldiers.

Today the accordion can be seen in the main exhibition of Dachau Concentration Camp Memorial Site.
