La Pallice is the commercial deep-water port of La Rochelle, France.
During the Fall of France, on 19 June 1940, approximately 6,000 Polish soldiers in exile under the command of Stanisław Sosabowski
arrived at La Pallice, from where they were evacuated to Great Britain - thus able to go on fighting till the end of the war.
Under the Nazi Occupation of France, La Pallice was used as a U-boat base from October 1941 when the 3rd U-boat Flotilla was moved there from its base in Kiel. La Pallice was subject to the allied siege of La Rochelle in 1944–45, which ended with the capitulation of Germany.
