8th Cavalry Brigade (United Kingdom) The 8th Cavalry Brigade was a cavalry brigade of the British Army in World War I. It was formed in Belgium in 1914 and served on the Western Front as part of the 3rd Cavalry Division. It left the 3rd Cavalry Division on 14 March 1918.
Hindenburg Line The Hindenburg Line ("Siegfriedstellung" or Siegfried Position) was a German defensive position of World War I, built during the winter of 1916–1917 on the Western Front, from Arras to Laffaux, near Soissons on the Aisne. In 1916, the German offensive at the Battle of Verdun had been a costly failure. The Anglo-French offensive at the Battle of the Somme had forced a defensive battle on the Germans, leaving the western armies ("Westheer") exhausted. On the Eastern Front, the Brusilov Offensive had inflicted huge losses on the Austro-Hungarian armies in Russia and forced the Germans to take over more of the front. The declaration of war by Romania had placed additional strain on the German army and war economy. Construction of the Hindenburg Line in France was begun by the Germans in September 1916, to make a retirement from the Somme front possible, to counter an anticipated increase in the power of Anglo-French attacks in 1917.
