Churchill had a fascination with the Balkans, which he considered to be one of the most suitable places for operations.  One of the recurring topics of his “Mediterranean strategy” was his plan for the Allies to land on the Adriatic coast of Yugoslavia and arrive in Austria through the Ljubljana breach in the Alps to claim Eastern Europe after the war.  The collapse of the German position in the Balkans again aroused Churchill`s interest in his plans for the Ljubljana gap, but a landing in Dalmatia would first require the conquest of northeastern Italy.  On 25 August, the 8th British Army launched Operation Olive, an offensive against the Gothic Line in northern Italy, led by the 1st Canadian Corps with the aim of recapitling Pesaro and Rimini, which were to serve as ports to support the planned British offensive in Yugoslavia.  Germany`s rigid resistance to the Gothic Line, which best exploited the defensive natural territory of northeastern Italy, crossed by mountains and 14 rivers, led the 8th army to advance much more slowly than hoped, causing the plans for the Ljubjana Gate to be put on hold.  In Triumph and Tragedy, the last of his books on the history of World War II, Churchill attacked the Americans for Operation Dragoon, the invasion of southern France, against which he opposed.  In a sign of bitterness that the Americans opposed his Mediterranean strategy, Churchill asserted that if only the servants of Operation Dragoon had made available manpower and resources for plans to promote the Ljubanja breach, the Allies would have taken Vienna in 1944, preventing the Red Army from conquering the city in 1945.  The Percentages Agreement was a secret informal agreement between British Prime Minister Winston Churchill and Soviet Head of State Joseph Stalin at the Fourth Moscow Conference in October 1944. It ceded the percentage of control over Eastern European countries and divided them into spheres of influence.
Franklin Roosevelt was consulted provisionally and was granted to the agreement.  The contents of the agreement were first published in 1953 by Churchill in the last volume of his memoirs. U.S. Ambassador Averell Harriman, who was to represent Roosevelt at these meetings, was excluded from the discussion.   The Percentages Agreement (also known as the “Naughty Document”) was an agreement between Soviet Prime Minister Joseph Stalin and British Prime Minister Winston Churchill on the division of different European countries into spheres of influence at the Fourth Moscow Conference in 1944.
