Operation Barbarossa: Nazi Germany's Invasion of the Soviet Union

Context

Introduction

What you'll learn: You'll see why Barbarossa began as an ideological bid for rapid conquest, why early victories proved deceptive, and how Soviet survival transformed World War II into a longer and far deadlier struggle.

Key forces

Hitler planned Barbarossa as an ideological war to destroy the Soviet state and build German empire in the east.
Initial German offensives produced huge encirclements and prisoner captures but did not force Soviet collapse.
Mass violence against civilians, Jews, and Soviet prisoners was central to the campaign, not a side effect.
Failure before in winter 1941 turned Barbarossa from planned blitzkrieg into prolonged attritional war.

Hitler Turns East

By late 1940, Hitler had defeated France and looked unbeatable in Europe. Instead of stopping, he decided Germany's next great target was the Soviet Union.

This decision was not only military. Hitler believed Germans needed more land in the east for food, resources, and settlement. He called this goal Lebensraum.

He also hated Bolshevism and saw the Soviet state as both a political and racial enemy. In Nazi thinking, destroying the USSR meant destroying an ideology and entire populations marked as inferior.

German leaders expected the Soviet Union to collapse quickly if struck hard. That confidence shaped everything that followed. The decision to turn east set up the largest and deadliest campaign of the war.

It also tied Germany to a fight of distance and survival that no quick battlefield win could truly settle.

The War Plan Takes Shape

As 1940 ended, German planners drew up Operation Barbarossa as a giant attack across almost all of western Soviet territory.

The plan used three main army groups. North would move toward , Center toward , and South into Ukraine. Each thrust aimed to trap Soviet armies and keep them from regrouping.

The distances were enormous. Railways, roads, fuel supply, and weather were major risks. But many planners believed these risks would not matter because they expected Soviet defeat in a few months.

This was the key assumption: one fast campaign before winter. It made the operation look possible on paper, but it also built in danger if the Soviet Union kept fighting.

When assumptions fail in a plan this large, the whole campaign can unravel faster than commanders expect.

The Invasion Begins

At dawn on 22 June 1941, Operation Barbarossa began. Germany and its allies attacked the Soviet Union across a huge front without warning.

The force was enormous: millions of troops, thousands of tanks, and powerful air support. Early air strikes hit Soviet airfields and communications, destroying many aircraft before they could fight.

Soviet border armies were shocked and often overwhelmed. Command systems broke down in many sectors, and German armored units pushed through quickly, creating deep gaps.

The opening days looked like total German success. But the scale of the attack also meant Germany had begun a war far larger than any campaign it had fought before.

What looked like unstoppable momentum in June hid the strategic risk of fighting a state that could retreat, rebuild, and return.
