About Henri Fertet
Henri Claude Fertet was a French schoolboy and resistance fighter who was executed by the German occupying forces during World War II. He was posthumously awarded several national honours. He is known for the letter he wrote to his parents on the morning of his execution, and he has become one of those who symbolise the French Resistance. His father too was named Henri; the sources do not record his mother's name. In February 1943, that group (which had about thirty members, Fertet being the youngest) integrated itself into the Francs-Tireurs et Partisans (FTP) under the name of Groupe Guy Mocquet.
