The Maréchal de Turenne, a three mast barque, was built in the "Chantiers de la Loire" shipyard in Nantes, port in the West of France, in 1899 by the company René Guillon et René Fleury. Capacity of 3000 barrels. The barque is called a "cap-hornier" in French. In a book written in 1973 by Georges Aubin, "La mer douce et cruelle", ed. France-Empire, a chapter "Une traversée du trois-mâts nantais Maréchal de Turenne" (page 285 to 319) tells how the ship was navigating from London to New-York to load barrels of petrol bound for Melbourne.The photograph demonstrates how prepared the merchant navy was during the First World War. The French Merchant Navy had additional men from the Navy: the six sailors in uniform and sailor "bachi" bonnet with the AMBC inscription were on the ship to support the crew in case of enemy attack. Two of those soldiers carry a bayonet. One of the sailors is wearing headphones: World War One saw telecommunication progress. At sea, the threat were the German submarines: the U-boats.The photograph depicting the 22 members of the crew was taken in October 1918 onboard the Marechal de Turenne. The two on the right and left side are holding a picture of the barque. One man at the back is holding a cat. 11 names are written at the back. The photograph was turned into a postcard.Printed at the back: On the left: Green Bros/Photo/251 Nelson Place, Williamstown Centered: Post Card/Correspondence/Address only Top right corner for the stamp: Kodak Australia Written at the back: octobre 1918 Souvenir du navire Maréchal de Turenne Berthot Jacquet Renaut R.
