When the civil war started in my country alternatives struggle led me to the main fronts where they were developed, as an infantry officer in the forces loyal to the Republic and, at the end of the war, I went to France where I was recluse for one year in a concentration camp. From there, the French took me as a prisoner to do work of fortification and the German advance made ​​me fall prisoner of these. I contributed, with the French forces of the interior, to the liberation of France and after twelve years of separation from my wife and son we were able to rebuild our home in the French capital.
