[2] In Paris, he became an acquaintance of fellow American expatriates Ernest Hemingway and Gertrude Stein, and the French painter André Masson.

He first drove ambulances and led American volunteers for the Lincoln Brigade from France into Spain across the Pyrenees, and then saw action as an infantryman in the battles of Jarama and Bruente, being badly wounded at Brunete.

[1] Evan Shipman is mentioned in Death in the Afternoon (1932), Hemingway's account of Spanish bullfighting, as a fellow admirer of a certain half-bred racehorse, a steeplechaser, named Uncas.

"Uncas, when he won a classic steeplechase race at Auteuil at odds of better than ten to one, carrying my money on him, I felt profound affection for.

But if you should ask me what eventually happened to this animal that I was so fond of that Evan Shipman and I were nearly moved to tears when speaking of the noble beast, I would have to answer that I do not know."
