During World War I, both Britain and France sent military forces to Italy in October 1917.
Following the Battle of Caporetto (24 October to 19 November 1917), the Italian Front collapsed. In order to ensure this did not lead to Italy withdrawing from the war the Allies organised forces to reinforce the Italians.<ref>{{cite web|last=Craig Johnson |first=Robert |title=After Caporetto: William Barker & the Italian Expeditionary Force |url=http://www.worldatwar.net/chandelle/v1/v1n1/barker.htm |publisher=Rocky Mountain Chapter, IPMS/USA |accessdate=4 December 2013 |url-status=bot: unknown |archiveurl=https://archive.today/20130413230653/http://www.worldatwar.net/chandelle/v1/v1n1/barker.htm |archivedate=13 April 2013 }}</ref> As the battle unfolded, General Luigi Cadorna invoked the agreement reached at the Chantilly Conference of December 1915.

The first French troops arrived on 27 October 1917. The first British troops followed them after a few days. Fearing that his troops would be overrun and lost in case the Italian lines on the Piave river would be broken by the Austro-Hungarian and German forces, however, General Ferdinand Foch refused to commit them to the frontline until the Italian troops had halted the Central Powers' troops by themselves and firmly established a defensive line on the Piave river. The British were thus kept in reserve during the First Battle of the Piave (November 1917) and only saw action from December 1917 onwards.

The British Expeditionary Force (Italy) came under the command of General Sir Herbert Plumer, who had formerly commanded the Second Army on the Western Front.
