Monumento aos mortos da Primeira Guerra Mundial in Coimbra, Portugal

Despite its old alliance with Britain, Portugal did not form a part of the system of alliances which became enemies in World War I and thus kept its neutrality during the first years of war. Portugal suffered from the German U-Boat warfare which sought to blockade the United Kingdom — at the time the most important market for Portuguese products. Clashes also occurred with German troops in the south of the Portuguese colony of Angola, but both the Portuguese and the German governments formally stuck to Portuguese neutrality.

1918

Haking visits the Portuguese troops and decides to send the 2nd Division to the rear from April 9, which would never happen.
