The army group remained isolated in the Courland Pocket until the end of World War II in Europe.

At the time agreed for all German armed forces to end hostilities (see the German Instrument of Surrender, 1945), the Sixteenth and Eighteenth armies of Army Group Courland, commanded by General (of Infantry) Carl Hilpert, ended hostilities at 23:00, on 8 May 1945, surrendering to Leonid Govorov, commander of the Leningrad Front.

Approximately 200,000 German troops in 26 divisions were in what was to become known as the Courland Pocket, pushed against the Baltic Sea in the West, the Irbe Strait in the North and the Gulf of Riga in the East.

On 7 May 1945, German Head of State (Staatsoberhaupt) and President (Reichspräsident) Karl Dönitz ordered Colonel-General Carl Hilpert, to surrender Army Group Courland.

Approximately 4000 Latvian soldiers went to the forests and formed partisan organizations to continue their fight against the Soviets and to gain independence for the Soviet-occupied Latvia.
