The Allied's campaign in Italy started off from the South and slowly moved northwards in the following two years, leaving the northern regions occupied by Germans and collaborationist forces for several years. Turin was not captured by the Allies until the end of Spring Offensive of 1945. By the time the vanguard of the armoured reconnaissance units of Brazilian Expeditionary Force reached the city, it was already freed by the Italian Partisans, that had begun revolting against the Germans on 25 April 1945. Days later, troops from the US Army's 1st Armored and 92nd Infantry Divisions came to substitute the Brazilians.
