54th Infantry Regiment (France)
The 54th Infantry Regiment (54e régiment d’infanterie or 54e RI) is a line infantry regiment of the French Army.

History

Early service 
It was formed in 1657 during the Ancien Régime as the régiment Mazarin-Catalans, being renamed the régiment Royal Catalan in 1661 then the régiment Royal Roussillon in 1667. The regiment was recruited in the regions of Perpignan, Roussillon and Catalonia. The regiment served at the Battle of Fontenoy in 1745 during the War of the Austrian Succession.

A second battalion of the Royal Roussillon served in Germany (1756–1762). In 1756, the 54th Infantry Regiment's uniform was white with blue facings, five gilded buttons for the linings and three buttons on each pocket. Its first battalion fought in Canada during the French and Indian War from 1756 to 1761, under the command of général Louis-Joseph de Saint-Veran, Marquis de Montcalm, with M. de Sennezergue as its colonel. The battalion arrived in New France in May 1756, and was originally posted to Montreal, with the exception of a detachment that was sent to Fort Carillon. It fought at the Battle of Fort William Henry. After that victory, the regiment took part in the 1758 Battle of Carillon. It then went to Quebec City to defend the city. At the Battle of the Plains of Abraham, it was broken and forced to flee by steady fire from the British 35th Foot, whose members are traditionally held to have picked up the 54th's plumes and placed them in their own headdress (the Roussillon Plume being formally incorporated into the badge of the 35th Foot in 1881).

The regiment participated in the battles of Montmorency, the Plains of Abraham and Sainte-Foy. At the subsequent siege of Quebec they were unable to subdue the garrison and had to retreat to Montreal. They could not fend off the British three pronged attack against Montréal in September and surrendered there.

Revolution and First Empire 
In 1791, just before the French Revolution, it lost its royal title and first became the 54th Line Infantry Regiment, then in 1793 the 54e demi-brigade de bataille (consisting of the 1st Puy-de-Dôme Volunteers’ Battalion and the 1st Indre Volunteers’ Battalion). From 1796, it was made up of the 43e demi-brigade de bataille (itself made up of 1st battalion of the 22nd Line Infantry Regiment, 4th Seine-et-Oise Volunteers’ Battalion, and the 3rd Lot Volunteers’ Battalion). In 1803, it reverted to its title of 54th Line Infantry Regiment. Distinguished at Barossa and led the assault on Le Haye Sainte at Waterloo. One battalion was present in the Wagram campaign. Between 1804 and 1815, it lost 23 officers killed, 89 wounded and 14 died of wounds. During this period it fought at:

1792: Battle of Valmy and Battle of Jemappes.
1793: Battle of Kaiserslautern.

1815–1914 
It became a ‘légion -Infanterie de ligne' from 1816 to 1820, reverting to 54th Line Infantry Regiment from 1820 to 1854 and finally taking its present name in 1854. From 1828 to 1833, it took part in the Morea expedition supporting Greek independence, especially the siege of the fort at Morea.

1914–1918 
On the outbreak of the First World War in 1914, the Regiment was on garrison duties at Compiègne as part of France's 23rd Infantry Brigade, itself part of 12th Infantry Division of 6th Army Corps, of which it formed part throughout the war. It took part in 3rd and 4th Armies' retreat, fighting from 5 to 13 September at Longwy, Vaux-Marie, Sommaisne, Rembercourt-aux-Pots, Mouilly and the First Battle of the Marne. It then fought in the Calonne (les Hauts de Meuse- Ouest des Eparges) sector of the trenches from 22 September 1914 to 2 August 1915. Les Eparges was a heavily-disputed sector, split between the regiments of France's 12th Infantry Division.

From January to May 1915, it fought in operations on the River Meuse and Argonne, both in les Eparges and the First Battle of Champagne. On 24 April that year, the Regiment was brought together to campaign near Rupt-en-Woëvre – before going, it performed a march past the general commanding 12th Infantry Division, who then decorated two of the Regiment's officers with the Légion d’Honneur. The Regiment was then mentioned in dispatches for its sustained fighting from 26 December onwards, when the Regiment was put on alert at lunchtime and went on to base itself on the edge of the Châtelaine forest opposite Mouilly. On Sunday 25 April it linked up with France's 132nd Infantry Regiment on its left. Under German 105 and 150 bombardment, the 54th was ordered to make its trenches unwinnable. The 87th Infantry Regiment had to attack before the 54th but the attack failed and night arrived.

In 1916, the Regiment saw action at Verdun and the Somme and the following year during the Chemin des Dames offensive. 1918 saw it fighting once again in the Somme, this time at Grivesnes, le Plessier and the Saint-Aignan offensive on the Aisne, then finally in the Flanders offensive.

1919–present
