Battleship Courbet

The battleship Courbet belonged to the class of the same name and was the first modern dreadnought battleship of the French Navy to be completed at the beginning of the First World War.


Launch and design:

With the launch of the British HMS Dreadnought in 1906, the concept of battleships changed fundamentally. The French battleships were equipped with different calibers like the Danton class, but until 1909 the attitude of the French naval leadership changed.

From 1910, Augustin Boué de Lapeyrère was the new minister in charge of the French naval ministry and also headed the 1906 programme for modernising and expanding the French fleet. Lapeyrère followed the models built in other countries at the time in proposing and designing new battleships. The ships of the Courbet were to have a length of 166 metres and a width of 27 metres with a maximum displacement of 25,850 tonnes.

Twelve 30.5 cm L/45 Model 1910 guns were selected as armament. These weapons were introduced as early as 1906 under the designation L/45 Model 1906, but were subsequently modified somewhat. These cannons were housed in twin turrets weighing 6 x 560 tons, with 2 turrets each at the front and rear and 1 turret each at the side. For the middle artillery the designers selected 22 x 13.86 cm guns L/55 model 1910. These were inferior to comparable warships from Great Britain and the German Reich, but these guns had a very good handling during the loading process and a higher firing speed. Further 4 x 45 cm torpedo tubes of the model 1909 were installed, whose tubes lay below the waterline.

In contrast to the later sister ships France and Paris, the Courbet and the Jean Bart 24 had Niclausse boilers to drive the two Parsons steam turbine sets built under licence, each with two propeller shafts. The aim was to achieve an output of 28,000 hp and a maximum speed of 21 knots (39 km/h). During later test drives, however, the speed was slightly undershot.

In order to counteract the increasing danger of torpedoes and such attacks, the armor of the ships' main armor has been reinforced. The 99 metre long and 4.75 metre high armour was 2.35 metres above and 2.40 metres below the waterline and was up to 270 mm thick.

The construction of the Courbet began after the order on September 1, 1910, the launch on September 23, 1911 and the commissioning on November 19, 1913.

Use in war:

After the commissioning, the test runs and a voyage with the French President Raymond Poincaré to Great Britain, the ship was assigned to the 1st Division de Ligne and served Vice Admiral Augustin Boué de Lapeyrère as flagship.

After the German Empire declared war on France on 3 August 1914, de Lapeyrère had his fleet split up to protect the troop transports from Algeria to France, since the German battle cruiser SMS Goeben was on its way in the Mediterranean Sea and its position was unknown.

After the declaration of war against Austro-Hungary on August 12, 1914, de Lapeyrère pulled his warships together and sent the battleships to Otranto in Italy and patrolled the armoured cruisers off the Albanian coast. On the 16th of August a battle took place with several Austro-Hungarian ships, during which the protected cruiser Zenta off Antivari could be sunk by the French ships. On 1 September the same battleships fired at Austro-Hungarian coastal fortifications near the Bay of Cattaro.

In the coming weeks, the ships patrolled between the Greek and Italian coasts to prevent the Austro-Hungarian fleet from departing. The battleship Jean Bart was attacked and severely damaged by the Austro-Hungarian submarine U-12 on 21 December. De Lapeyrère then withdrew his battleships after realising that they were still insufficiently protected against submarine attacks.

At the beginning of 1915, the French naval command received information that the Austrian-Hungarian fleet was leaving. De Lapeyrère then allowed his ships to leave on 11 January 1915 and patrol off the Albanian coast. After the information turned out to be false, the ships returned to their ports. Italy's declaration of war against Austria-Hungary on 23 May 1915 led to Italian warships monitoring the coasts and French ships retreating to their ports in Malta or Bizerte. The rest of 1915 was used to carry out some conversions on the battleships and to exchange the smaller guns.

From 27 April 1916, the French navy was also able to use the port of Argostoli on the Greek island of Kefalonia as a base and moved most of its ships there. Since the battleships were hardly used any more, parts of the crew were retrained on the submarines and used with these.

At the beginning of 1917 the Greek island Corfu could also be used as a base besides Argostoli, but the increasing shortage of coal and the limited range of use of the warships became apparent. From 1918, the shortage was so great that the warships were almost no longer operational. The last year of the war was therefore mainly used for reconstruction measures and the Courbet was assigned to the 2nd battle department of the 1st fighter squadron on 1 July 1918 and remained there until the end of the war.

Post-war deployment:

After the end of the First World War, the Courbet was ordered back to the port of Toulon and overhauled there. Until 10 February 1920 it was also allocated to the reserve until the restructuring of the French fleets was completed and the ship was assigned to the western Mediterranean squadron. On 20 July 1921 this was merged with the eastern Mediterranean squadron to form the Mediterranean squadron again.

In the following years the Courbet served for the training until on 6 June 1923 in the boiler plant a fire was released and the propulsion plant heavily damaged. Until 16 April 1924 the ship was in Seyne-sur-Mer and received some new boilers of the type Du Temple as well as some modifications. For example, the range of the guns was increased by the tubes rising much steeper and the air defence guns were replaced by 75 mm Modèle AA guns from 1918. After completion of the repair and conversion work, another fire broke out in the boilers on August 1, 1924, causing 10 sailors to be seriously injured and 3 to die.

After also the renewed damage at the boilers was repaired, some maneuvers were accomplished in the following years until the ship was extensively modernized starting from 15 January 1927 in Toulon. The ship received a complete exchange of the boilers against 6 oil boilers and 16 coal boilers, which were originally built for the already scrapped battleship Normandie. Furthermore the fire control system, the rangefinders and some guns were replaced by more modern versions. The conversion measures were on 12 January 1931. During subsequent test runs, however, it turned out that the maximum speed had fallen with the installed propulsion system and that the first turbine had already been damaged on 25 March 1931.

After the renewed repair the Courbet was assigned to the training unit and served there until the unit was dissolved on 10 June 1939. Subsequently it was divided into the 3rd Battle Division of the 5th Squadron.

Use in the Second World War:

After the beginning of the Second World War, the battleship Courbet, together with its sister ship Paris, initially continued its training missions. Only after the invasion of the German Wehrmacht on 10 May 1940 in Belgium and France were the ships put on alert and reactivated as warships. Under the leadership of Vice Admiral Jean-Marie Abrial, the ships were used to defend the French ports on the English Channel. Thus, on 19 June, the Courbet supported the defence of Cherbourg against the advancing German 7th Panzer Division and the subsequent evacuation of the city. After this was completed, the ship called at the British port of Portsmouth, where other French warships also arrived, which were brought to safety from the German Wehrmacht.

After France capitulated, the British army started the confiscation of the interned French warships on 3 July 1940 under the name Operation Catapult so that they were not delivered to Germany. A week later the British troops transferred the Courbet to the Free French Army, which had been established in Great Britain.

First the ship was equipped with further anti-aircraft guns to protect the harbour against German bombers. Until 31 March 1941 all weapons were dismantled and the rest of the ship was used as accommodation.





In the course of planning and preparing an Allied invasion of northern France, the Courbet was assigned as one of the breakwaters. The ship's propulsion system was then completely dismantled and concrete pedestals were placed inside to weigh the ship down. On 7 June 1944 the Courbet was towed by 2 British tugs from Weymouth to Sword Beach, where it ran aground on 9 June and was sunk with torpedoes from 15 to 17 August.

After the war, work began on scrapping the wreck. These were only completed in 1970.

French Battleships 1914–45 (New Vanguard)

French Battleships 1914–45 (New Vanguard) Paperback – January 22, 2019

This authoritative study examines the French Navy's last battleships, using detailed color plates and historical photographs, taking them from their inception before World War I, through their service in World War II including the scuttling of the French fleet at Toulon in 1943, and the service of Richelieu in the war against Japan.

On September 1, 1910, France became the last great naval power to lay down a dreadnought battleship, the Courbet. The ensuing Courbet and Bretagne-class dreadnoughts had a relatively quiet World War I, spending most of it at anchor off the entrance to the Adriatic, keeping watch over the Austro-Hungarian fleet. The constraints of the Washington Naval Treaty prevented new battleships being built until the 1930s, with the innovative Dunkerque-class and excellent Richelieu-class of battleships designed to counter new German designs.

After the fall of France in 1940, the dreadnoughts and fast battleships of the Marine Nationale had the unique experience of firing against German, Italian, British, and American targets during the war.

French Battleships of World War One

French Battleships of World War One Hardcover – June 15, 2017

When war broke out in August 1914 France had only two dreadnoughts in service, with a second pair running trials. The main body of the elite Armée Navale was made up of the eleven battleships of the Patrie and Danton classes, both of which were intermediate designs with two main gun calibers. Older ships included survivors of the notorious Flotte d'echantillons ('fleet of samples') of the 1890 program and their successors designed during the 1890s.

This book traces the development of French battleships from 1890 to 1922, and also covers the extensive modifications made to the survivors during the interwar period. It is liberally illustrated throughout with line drawings and labelled schematics, plus photographs from the extensive Caresse collection, many of which are previously unpublished.

This is the most comprehensive account of these ships published in English or French, and is destined be the standard reference for many years to come.

French Armoured Cruisers 1887–1932

French Armoured Cruisers 1887–1932 Hardcover – November 1, 2019

Of all the threats faced by the Royal Navy during the first years of the twentieth century, the one which stood out was the risk to Britain's sea lines of communication posed by France's armored cruisers. Fast, well-armed, and well-protected, these ships could have evaded any attempted blockade of the French ports and, supported by a worldwide network of overseas bases, could potentially have caused havoc on the trade routes.

The primary focus of the book is on the technical characteristics of the ships. Detailed and labeled drawings based on the official plans are provided by John Jordan, and each individual class of ship is illustrated by photographs from the extensive personal collection of Philippe Caresse. The technical section is followed by a history in two parts, covering the Great War (1914-18) and the postwar years, during which the surviving ships saw extensive deployment as "station" cruisers overseas and as training ships. This is the most comprehensive account published in English or in French and is destined to be the standard reference for many years to come.

To Crown the Waves: The Great Navies of the First World War

To Crown the Waves: The Great Navies of the First World War Hardcover – July 15, 2013

The only comparative analysis available of the great navies of World War I--each chapter is written by a recognzed expert fluent in the subject language. The work studies the Royal Navy of the United Kingdom (John Roberts), the German Kaiserliche Marine (Dr. Peter Schenk with Axel Niestlé and Dieter Thomaier) the United States Navy (Trent Hone), the French Marine Nationale (Jean Moulin), the Italian Regia Marina (Enrico Cernuschi and Vincent P. O'Hara) the Austro-Hungarian Kaiserliche und Königliche Kriegsmarine (Zvonimir Freivogel), and the Imperial Russian Navy (Stephen McLaughlin) to demonstrate why the war was won, not in the trenches, but upon the waves. It explains why these seven fleets fought the way they did and why the war at sea did not develop as the admiralties and politicians of 1914 expected.

After discussing each navy's goals and circumstances and how their individual characteristics impacted the way they fought, the authors deliver a side-by-side analysis of the conflict's fleets, with each chapter covering a single navy. Parallel chapter structures assure consistent coverage of each fleet--history, training, organization, doctrine, materiel, and operations--and allow readers to easily compare information among the various navies. The book clearly demonstrates how the naval war was a collision of 19th century concepts with 20th century weapons that fostered unprecedented development within each navy and sparked the evolution of the submarine and aircraft carrier. The work is free from the national bias that infects so many other books on World War I navies. As they pioneer new ways of viewing the conflict, the authors provide insights and material that would otherwise require a massive library and mastery of multiple languages. Such a study has special relevance today as 20th-century navies struggle to adapt to 21st-century technologies.
