The Capture of Stuff Redoubt (Feste Staufen) was a tactical incident in France, during the Battle of the Somme in 1916. The redoubt had been built as part of the fortification of the Somme front by the German 2nd Army (General Fritz von Below) after the open warfare of 1914. On 1 July, the First Day on the Somme, troops of the 36th (Ulster) Division occupied part of the redoubt before being forced to retreat by German counter-attacks. British troops were not able to reach the redoubt again until the Battle of Thiepval Ridge (26–28 September) when parties of the 11th Division captured part of the redoubt. The rest of the redoubt was taken by the 25th Division during the Battle of the Ancre Heights (1 October – 11 November).
