Since 1940, the Americans plan a landing in North Africa to open a second front in the West and thus relieve the Russian armies. The second and more secret objective is to take military power in colonized French regions. Operation Torch was organized in 1942 and allowed Allied troops to land in Algeria. The country is immediately placed under American administration, which however maintains the specificities of operation of the Vichy regime. The Americans land with so-called "Silver Certificates" which only have military use but help to rearm the African army. Emissions of the Bank of Algeria is continuing in parallel until 1945 with:
