On what date did the German offensive of which the First Battle of Villers-Bretonneux was a part begin?
Spring Offensive The 1918 Spring Offensive or Kaiserschlacht ("Kaiser's Battle"), also known as the Ludendorff Offensive, was a series of German attacks along the Western Front during the First World War, beginning on 21 March 1918, which marked the deepest advances by either side since 1914. The Germans had realised that their only remaining chance of victory was to defeat the Allies before the overwhelming human and matériel resources of the United States could be fully deployed. They also had the temporary advantage in numbers afforded by the nearly 50 divisions freed by the Russian surrender (the Treaty of Brest-Litovsk).
Battle of Hill 60 (Western Front) The Battle of Hill 60 (17 April – 7 May 1915 ) took place near Hill 60 south of Ypres on the Western Front, during the First World War. Hill 60 had been captured by the German 30th Division on 11 November 1914, during the First Battle of Ypres (19 October – 22 November 1914 ). Initial French preparations to raid the hill were continued by the British 28th Division, which took over the line in February 1915 and then by the 5th Division. The plan was expanded into an ambitious attempt to capture the hill, despite advice that Hill 60 could not be held unless the Caterpillar nearby was also occupied. It was found that Hill 60 was the only place in the area not waterlogged and a French 3 × mine gallery was extended.
