The Battle of Britain is over. The Luftwaffe has been driven to exhaustion, and Germany suffers its first major defeat. Even though Britain remains undefeated, it is so isolated that Hitler has no concerns about turning his attention East. Operation Barbarrossa, the German invasion of the USSR, takes the Soviets completely by surprise and the Red Army suffers terrible casualties.

After the swift success at Smolensk, Hitler has diverted the bulk of Heinz Guderian's panzers down to the South, so as to capture the Ukrainian capital Kyiv, considered more important than Moscow in Hitler's mind. It begins a gigantic clash and turns out to be the biggest military encirclement in history.

Erich von Manstein's soldiers have trapped a massive Soviet force in Crimea, but the doomed troops have no intentions of surrendering, obeying Stalin's brutal "Not A Step Back" order. Manstein assembles the greatest concentration of artillery in history, which includes the world's biggest railway-gun nicknamed "Dora," and for eight months Soviets troops are savagely bombarded.

October 1941, Germany's Army Group Center is only some 25 km west of Moscow. The Russian winter, however, is only a few weeks away. With not enough soldiers or military equipment, the Soviet high command's only hope left is that the weather will save the capital. The battle ends in a bloody failure for the German Army, and it is forced to retreat.

Leningrad, a vital and large Baltic sea port, is facing the entire weight of Army Group North. The Soviets have no reserves to spare as the Battle of Moscow is about to begin. Wilhelm von Leeb's Army Group North fails to take Leningrad, but begins a horrible siege that will last 872 days, in which over a million civilians will die of starvation and disease.

The capture of Rzhev, the city that connects all railroads in Western Russia, is imperative. It will cost the lives of some 3 million Soviet soldiers and 500 000 German soldiers. It will take the Soviets a total of 3 years to throw the Germans firmly out of the city. These bloodbaths will become known by the veterans and historians as "The Rzhev Meat-Grinder."

The Nazis invade the oil rich Caucasus to cut off this critical source of fuel to the Soviets. Standing in the way is Staligrad. Without realizing the strategic error they are making the Nazis reduce the city to rubble through air and artillery bombardment. The rubble serves as an ideal environment for an extended urban battle where the vaunted Blitzkrieg is useless. The error costs the Nazis dearly in men and materiel which the Nazis need for the Battle of Moscow and time the Soviet's use to rearm. Worst, The Nazis fail in their objective to capture the Caucuses.

After the failure to take both Moscow and Leningrad, Hitler sets his sights on the oil fields in the Caucasus. If captured, the Red Army will lose 70%-90% of all its oil resources. Therefore, the famous city on the Volga, Stalingrad, must be "held at all costs." The German General Staff thinks taking the city will be a matter of a few weeks, but events steadily turn against the Germans.

in the summer of 1943 Nazi forces armed with new advanced weaponry launch Operation Citadel expecting success comparable to their last two summer offensives. Their plan is to encircle the Soviet forces in a large salient near Kursk. But the battle plan is obvious and the Soviets are fore-warned, deeply entrenched and much better armed and experienced than in previous summer campaigns. Ironically, the Nazi's top defensive commander will lead the offensive while the Soviet's top offensive tactician will play defense. The result is incredible carnage and a fatal defeat for the Nazi invasion of Russia.

Soviet forces advancing on Kiev are briefly stalled at the Dnieper River until a tank unit crosses a shallow ford and promptly drives the Nazis from the city. The Soviet charge through Ukraine becomes a war of attrition for the Nazis which are quickly weakened to the point they can no longer counter attack. The Soviets soon capture the critical Romainian oilfields. As they drive into Hungary, Hitler reinforces his southern forces with units badly needed to defend against the Soviet main offensive in the German homeland.

In 1944 it is the Soviet's turn for a summer offensive. They quietly prepare a massive assault in Beyelosussia under cover of darkness and a successful campaign in the Urkraine that convinces the Nazis to move units defending Beyelosussia to the Ukraine. The Soviets unleash a blitzkrieg style surprise attack in Beyelosussia that succeeds beyond their wildest dreams and to the disbelief of the Soviet's allies. Hitler's demand that German forces hold their positions ultimately depletes Nazi forces as one army sized unit after another is encircled and destroyed.

On the eve of Operation Barbarosa the Luftwaffe out classed the Soviet Air Force in pilot training and experience, battle tactics, aircraft capability and armament and very soon, aircraft quantity. Yet the Red Air Force steadfastly stood up to the Luftwaffe making gradual progress in all these area through not quite reaching parity by the close of World War Two. But by then Soviet aircraft vastly out numbered the Luftwaffe which could not compete with Soviet production capacity and combat attrition. Take a close look at the Soviet fighter aircraft and meet the stellar pilots of the war.

Soviet naval strategy during World War Two deliberately focused on submarine warfare. So the Soviets maintained a relatively small surface navy. While the Baltic surface fleet was important for the defense of Leningrad, most other important engagements involved submarines. Notable are the sinkings of two Turkish freighters in the Black Sea that were loaded with chrome ore, a minor but crucial component of steel. The Nazis managed to marginalize the Baltic fleet with a submarine net midway through the war. But the Soviet-Finnish armistice signed late in the war enable Soviet ships to escape to harass the German withdrawal from Poland.

The Soviet partisan movement began immediately after the commencement of Operation Barbarossa. It was centrally commanded by OMSBON, very active and well organized to coordinate operations with the Red Army's military objectives. In 1941 the Soviets had very few experienced guerrilla commanders since the majority had succumb to Salin's purges so many. many partisan units were lost that year. But as the war continued partisan manpower grew to the equivalent of 30 army divisions. Despite their thousands of successful raids few had a major impact even in toto. But their ongoing operations successfully diverted and distracted the Nazis from battlefield operations sometimes resulting in Nazi units being pulled from the front lines to combat them.

On the eve of Operation Barabarossa Soviet spies under cover as embassy employees were expelled from Nazi occupied countries effectively ending Soviet espionage about Nazi Germany. Thereafter the Soviet's intelligence on the Nazis was limited to espionage networks in other Axis countries such as Richard Sorge's spy ring in Japan. But as the war progressed the Soviets succeeded in embedding a cadre of double agents in the Wemehr who were secretly working for the NKVD passing disinformation to the Nazis and sending Nazi intelligence to the Soviet Union.

Soviet forces traverse Poland quickly as they encounter relatively few major army units. The volkssturm, national militia, that Hitler hoped would offer fanatical resistance, were poorly armed and surrendered quickly, on one occasion, without a shot fired. But on German soil Hitler's festung, fortress city, concept is taken seriously, in part due to the Soviet army's brutal retribution against the civilians. Then at Koenigsberg the Nazis commit several SS divisions in a fierce but unsuccessful defense.

Germany has without question lost World War II in Europe, but Hitler, by now a heavily medicated and deluded character, refuses to give up hope; he orders the roughly one million German soldiers left in the ruined city to defend Berlin, now a strange mix of combat veterans, teenage boys from the Hitler Youth, and old men from the People's Army.

In exchange for territorial concessions Stalin agreed to join the war against Japan within 90 days of Germany's surrender negating the 1941 armistice with Japan. Exactly ninety days later Soviet forces invaded Manchuria, a region critical to Japan for fuel and other raw materials. Despite major logistical challenges including a mountain barrier, the battle hardened Soviets achieved rapid victories against the obsolete Japanese forces. Coupled with the nuclear bombing of the Japanese homeland, the Japanese finally decided to consider surrender. But the Japanese delayed, first hoping to negotiate better surrender terms and then failing to call a prompt cease fire after their surrender. During the interim Soviet forces were able to occupy and retain after the war Sakhalin and the Kiril islands.
