  • Germany Invades Czechoslovakia

    Germany Invades Czechoslovakia
    Britain and France acquiesced to Germany's rearmament (1935-37), remilitarization of the Rhineland (1936), and annexation of Austria (March 1938). In Sept. ‘38 the Czech border regions, the Sudetenland, were signed away to Germany. B and F responded by guaranteeing the integrity of Poland. Hitler negotiated a nonaggression deal, the German-Soviet Pact of August 1939, which would partition Poland between the two powers. It enabled Germany to attack Poland without fear of Soviet intervention.

  • Westerplatte, Poland

    Westerplatte, Poland
    Germany invaded Poland without warning sparking the start of World War Two. By the evening of September 3rd, Britain and France were at war with Germany and within a week, Australia, New Zealand, Canada and South Africa had also joined the war. Westerplatte's unexpectedly fierce resistance delayed the German occupation of the narrow Polish coastline, thereby indirectly saving the Polish Navy and embarrassing the Germans. The battle lasted until Sept. 7.

    Invasion of France--Sedan
    The tactics of Blitzkrieg -- panzers working in close corrdination with the artillery and dive bombers (Stukas) -- achieved conspicuous successes. Germany's area of victories extended from the "impregnable" French Maginot line to Belgium, the edge of the English Channel, and the Netherlands to the north. French forces in the Allied line's vital center were shattered. In the north, Dutch armed forces were all but destroyed. The battle lasted until may 28.
  • Dunkirk

The Kriegsmarine mounted no more serious surface threat to Allied shipping in the Atlantic. The battle lasted until May 27.
  • Operation Barbarossa

    Operation Barbarossa
    Barbarossa was the decisive turning point of the war. If the Soviet Union survived the German onslaught of 3.3 million men and 3,000 tanks, Hitler's Reich would face a two-front war. By July 1941, when Finland had joined the German onslaught in the north, the Eastern Front would eventually stretch from the Black Sea to the Arctic North and the Germans would almost reach the gates of Moscow. The battle lasted until Dec. 5, 1941.
  • Siege of Leningrad

    Siege of Leningrad
    A partial blockade of Leningrad by Army Group North reduced the city to starvation conditions, the blockade being broken only by a succession of Soviet offensives over nearly three years. Leningrad was an early target of Operation Barbarossa, but by the end of 1943 the German operations there had little military function besides maintaining the overall German frontline. A million civilians died from starvation, bombing, and shelling. The siege lasted until Jan. 27, 1944.
  • Pearl Harbor Attacked

    About 500 miles northeast of Australia. In the spring of 1942, Japanese forces planned to invade southern New Guinea, designed to knock Australia and New Zealand out of the war. Though a draw, it was an important turning point in the war in the Pacific because, for the first time, the Allies had stopped the Japanese advance. Before the battle, the Japanese had enjoyed a continual string of victories while afterwards, it suffered an almost continual series of defeats. Lasted until May 8.

The battle lasted until Feb. 9, 1943.
  • Stalingrad

    This was part of a German campaigning to occupy the Soviet Union's southern oilfields in the Caucasus. German forces nearly succeeded in conquering Stalingrad, but with massive losses. A Soviet counteroffensive trapped 250,000 Germans within the city. About 100,000 were killed and 110,000 went to almost certain death in Soviet captivity. Stalingrad marked the beginning of the German defeat on teh Eastern Front. The battle lasted until Feb. 2, 1943.
  • El Alamein

    El Alamein
    El Alamein was a small Egyptian railway halt, 60 miles west of Alexandria. Growing British material strength allowed Montgomery to shift decisively to the offensive against Rommel's over-extended forces and finally ensure the safety of the Suez Canal and the Middle Eastern oil fields. Though Rommel was able to escape with a large proportion of his army, El Alamein marked a clear turning point in the Western Desert Campaign, shifting decisively to the Allies. The battle lasted until 11/4/42.

  • Anzio

    The Allied VI Corps suffered over 29,200 combat casualties. German combat losses were estimated at 27,500. The Anzio Campaign continues to be controversial. Allied forces were quickly pinned down and contained within a small beachhead, and they were effectively rendered incapable of conducting any sort of major offensive action for four months. Yet the Anzio beachhead guaranteed that the already steady drain of scarce German troops and materiel would continue unabated. Battle ended May 25.
  • Monte Cassino

    Monte Cassino
    Area surrounding Monte Cassino and the nearby town, just over 62 miles south of Rome. Cassino controlled the mouth of the Liri Valley and thus the most straightforward route to Rome.

  • Breakout from Normandy

    Breakout from Normandy

It was a decisive strategic victory. The fighting lasted until Aug. 30.
  • Warsaw Rising

    Warsaw Rising
    More than 40,000 Polish irregulars fought 25,000 Germans, who had occupied Poland for 4 years. It was part of a nationwide rebellion intended to last for only a few days until the Soviet Army reached the city. However, it developed into a long urban guerrilla campaign. The uprising was ultimately put down with great losses on both sides. It is estimated that more than 200,000 civilians died in the fighting, while 700,000 were expelled from Warsaw. The fighting lasted until October.
  • Operation "Market Garden"

    Operation "Market Garden"
    Allied airborne and ground forces were opposed by German armored and infantry units, near Arnhem, Netherlands on the Rhine River.

  • Battle of the Bulge/Ardennes

    Battle of the Bulge/Ardennes
    Hitler hoped to divide Allied army groups in the West, drive to the port of Antwerp, and change the course of the war. He sought to gain time to confront the coming Soviet offensive along the Vistula River. The battle resulted in a disastrous defeat for the Nazis. Fewer than 4 months later, WW II in Europe was over. This battle lasted until Jan. 15, 1945.
  • Vistula

    Successful offensive took Soviet forces from the Vistula river in Poland to the Oder river then deep in Germany, about seventy kilometers from Berlin.

Mandalay was captured on 20th March by 19th Indian Division. 2 months later Rangoon fell and Japanese troops retreated. Battle lasted until May 1.
  • Okinawa

    The Allies launched the largest amphibious operation of the Pacific campaign. They captured Okinawa and 90% of the buildings on the island were completely destroyed. Okinawa provided fleet anchorage, troop staging areas, and airfields in close proximity to Japan, allowing the Allies to prepare for the invasion of Japan.
