the Axis troops. The Allied offensives in Italy had succeeded and, at the expense of allowing several German divisions to retreat, on 4 June Rome was captured. The Allies had mixed success in mainland Asia. In March 1944, the Japanese launched the first of two invasions, an operation against Allied positions in Assam, India, and soon besieged Commonwealth positions at Imphal and Kohima. In May 1944, British and Indian forces mounted a counter-offensive that drove Japanese troops back to Burma by July, and Chinese forces that had invaded northern Burma in late 1943 besieged Japanese troops in Myitkyina. The second Japanese invasion of China aimed to destroy China's main fighting forces, secure railways between Japanese-held territory and capture Allied airfields. By June, the Japanese had conquered the province of Henan and begun a new attack on Changsha. Allies close in (1944) 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 on 25 August by the local resistance assisted by the Free French Forces, both led by General Charles de Gaulle, 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 failed. After that, the Western Allies slowly pushed into Germany, but failed to cross the Rur river in a large offensive. In Italy, Allied advance also slowed due to the last major German defensive line. On 22 June, the Soviets launched a strategic offensive in Belarus ("Operation Bagration") that almost completely destroyed the German Army Group Centre. Soon after that, another Soviet strategic offensive forced German troops from Western Ukraine and Eastern Poland. The Soviets formed the Polish Committee of National Liberation to control territory in Poland and combat the Polish Armia Krajowa; the Soviet Red Army remained in the Praga district on the other side of the Vistula and watched passively as the Germans quelled the Warsaw Uprising initiated by the Armia Krajowa. The national uprising in Slovakia was also quelled by the Germans. The Soviet Red Army's strategic offensive in eastern Romania cut off and destroyed the considerable German troops there
