When World War One broke out in 1914, Portugal was a neutral country. However colonial clashes in Africa, in Angola, and the effect of the German U-boats on Portuguese trade routes to the UK, her main partner, caused tensions with Germany. In February 1916, Portugal at Britain's request seized German and Austro-Hungarian shipping in Portuguese ports, and a month later Germany declared war on Portugal.
In response to the declaration Portugal raised an expedition force of an infantry division of 55,000 men, The Portuguese Expeditionary Corps (Corpo Expedicionário Português or CEP). The CEP deployed to the Western Front in February 1917 and came under the command of the British Expeditionary Force.

Portuguese Independent Artillery Corps
The French Army requested assistance from the Portuguese on 26th December 1916 for artillery personnel to man French heavy artillery batteries. In response an independent Heavy Artillery Corps (Corpo de Artilharia Pesada Independente or CAPI) was formed in January 1917. The CAPI would come under French Army command and operate independently of the Portuguese Expeditionary Force (CEP). The personnel would be recruited from the Army together with some Navy personnel.
