World War II (or the Second World War) was a major worldwide conflict that followed what was then known as the Great War in bringing nations across the globe to fight once again. The war began in 1939 with the declaration of war on Germany by France and the United Kingdom, following the German invasion of Poland. It ended following Japan's surrender to the United States of America in 1945. The main players in the war were the Axis powers (Germany, Italy, and Japan) and the Allied powers (France, United Kingdom, United States, Soviet Union, and China). The results of the war were the defeat of fascist regimes in Germany and Italy, the rise of the United States and Soviet Union as the dominant superpowers, and the beginning of the Cold War.
Prelude to warEdit
In his adventures during and after World War I, Indiana Jones saw hints of how another conflict might come to pass. After being captured in the Battle of the Somme in 1916, Jones met fellow prisoner of war Charles de Gaulle, who predicted that "the next great war will be fought with tanks and airplanes". While at the 1919 Paris Peace Conference, T. E. Lawrence also predicted such a war to his friend Jones. Although all three men played a role in the first world war, Lawrence never saw World War II come to pass, as he died in a motorcycle accident in 1935. Jones and de Gaulle became involved however; de Gaulle later led the Free French Forces—eventualy becoming the first president of the French Fifth Republic.
Adventures in World War IIEdit
Though the war had already been fighting for two years in Europe and Asia, the United States did not enter the war until after the Japanese attacked Pearl Harbor in December 1941. Prior to this time, Jones had been contacted for a few missions by US Army Intelligence against Nazi searches for the Akashic Hall of Records and at Mount Sinai. By 1942, Jones, with his background in intelligence, joined the Office of Strategic Services, along with Sophia Hapgood, and had become friends with MI6 agent George McHale and General Bob Ross,. Jones and McHale regularly worked together during the conflict, disguising themselves as Nazis to steal the cipher machine responsible for generating Germany's Enigma codes. McHale had to save Jones' life again when they traveled to Jakarta, Indonesia when Jones felt the needle of amnesia darts. In 1942, they went on a mission to Flensburg. In the summer of 1943, Jones and McHale took a brief leave and went in search of the Heart of Darkness, a black pearl, in Haiti, though ended up in the middle of a race between German and Japanese spies in search of an invincibility formula.
Around D-Day (June 6) 1944, Jones received a form "go-get-em" letter from General Dwight D. Eisenhower. At this time, McHale also entrusted Jones with a letter to Penelope in the case that McHale was killed. Jones kept both of these letters in his journal.  At some point during the war, Jones and McHale also worked as double agents in Berlin, and also served in the Pacific theater.
In 1945, Jones and McHale were in Flensberg for the final action, perhaps in conjunction with the British effort to arrest the "Flensberg government" which took civilian power after Hitler's death. Jones kept a newspaper clipping from "The Sun" of the May 4 Nazi surrender in his journal.
