The three nations agreed that for the next ten years they would "stand by and co-operate with one another in... their prime purpose to establish and maintain a new order of things... to promote the mutual prosperity and welfare of the peoples concerned." They recognized each other's spheres of interest and undertook "to assist one another with all political, economic and military means when one of the three contracting powers is attacked" by a country not already involved in the war, excluding the Soviet Union.

National Revolutionary Army

On 6 June 1944 (known as D-Day), after three years of Soviet pressure, the Western Allies invaded northern France. After reassigning several Allied divisions from Italy, they also attacked southern France. These landings were successful, and led to the defeat of the German Army units in France. Paris was liberated by the local resistance assisted by the Free French Forces on 25 August and the Western Allies continued to push back German forces in Western Europe during the latter part of the year. An attempt to advance into northern Germany spearheaded by a major airborne operation in the Netherlands ended with a failure. After that, the Western Allies slowly pushed into Germany, unsuccessfully trying to cross the Rur river in a large offensive. In Italy the Allied advance also slowed down, when they ran into the last major German defensive line.
