Denmark during World War I

[1] Denmark maintained trade with both sides of the war, and was among several neutral countries that exported canned meat to the German army.

The war brought to the fore the fact that Copenhagen's old fortifications from the 1880s and 1890s were obsolete and too near the capital to protect it from modern artillery bombardment.

[1] The Germans had already begun to mine Danish territorial waters in order to protect Germany from a British naval offensive.

During the war, more than 30,000 ethnically Danish men from the Southern Jutland region in the Prussian Province of Schleswig-Holstein served in the German armed forces.

[1] A Danish military cemetery exists for soldiers fallen whilst fighting for Germany in the French commune of Braine in France.
