Operation Alberich (German: Unternehmen Alberich) was the code name of a German military operation in France during the First World War.[lower-alpha 1] Two salients had been formed during the Battle of the Somme in 1916 between Arras and Saint-Quentin and from Saint-Quentin to Noyon. Alberich was planned as a strategic withdrawal to new positions on the shorter and more easily defended Hindenburg Line (German: Siegfriedstellung).

Planned | 1916–1917 |
Planned by | Field Marshal Rupprecht von Bayern |
Commanded by | Quartermaster-General Erich Ludendorff |
Objective | Retirement to the Hindenburg Line |
Date | 9 February 1917 (1917-02-09) – 20 March 1917 (1917-03-20) |
Executed by | Army Group Rupprecht of Bavaria (Heeresgruppe Kronprinz Rupprecht von Bayern) |
Outcome | Success |
General Erich Ludendorff was reluctant to order the withdrawal and hesitated until the last moment. The retirement took place between February 9 and March 20, 1917, after months of preparation. The German retreat shortened the Western front by 25 mi (40 km). The withdrawal to the chord of the Bapaume and Noyon salients provided 13 to 14 extra divisions for the German strategic reserve, that was being assembled to defend the Aisne front against the Franco-British Nivelle Offensive, preparations for which were barely concealed.
