The Portuguese Expeditionary Force fought in the trenches of northern France from April 1917 to April 1918. on 9 April 1918 the sledgehammer blow of Operation Georgette fell upon the exhausted Portuguese troops. British accounts of the Portuguese Corps’ participation in combat on the Western Front are terse. Many are dismissive. in fact, Portuguese units experienced heavy combat and successfully held their ground against all attacks. Regarding Georgette, the standard British narrative holds that most of the Portuguese soldiers threw their weapons aside and ran. the account is incontrovertibly false. Most of the Portuguese combat troops held their ground against the German assault. This thesis details the history of the Portuguese Expeditionary Force.
