“..I write you from the French front where I'am serving as a soldier in the Russian ambulance Corps. How are you feeling and what are you doing? How are your friends, Lissitsky, Libakov [also former students of Pen], Mazel, Mekler, and Chagall? Please, for God's sake, answer me. I would be so glad to hear how everyone is.I'm in fine health, but tired of it all – it's utterly disgraceful, makes the soul turn cold. If only it [the war] would just end.What are you working on, what are you doing? Please write me. – Yours Zadkine.”
