The flames of the Second World War swept across Europe, North Africa, the Atlantic, Asia, and the Pacific, and even the frozen Arctic, but the worst of them all, the Eastern Front, or as the Soviets called it, the Great Patriotic War, stands as humanity’s most brutal conflict. Combining the largest scale of land combat in history, deliberately cruel policies towards civilians and prisoners of war, extreme climate conditions, the ruthlessness of both regimes toward their own people, and the highest absolute death toll ever recorded on a single battlefield, this theater of war redefined the limits of human suffering. From June 1941 to May 1945, Nazi Germany and the Soviet Union, along with their allies, gave everything they had to utterly destroy each other, and they almost did.
The signing of the non-aggression pact between Germany and the Soviet Union in 1939, which shocked the entire world, should have prevented this conflict, but Hitler needed peace in the East while conquering the West, using the pact merely to buy time. This racial and ideological war of annihilation, known in German as Vernichtungskrieg, began on June 22nd, 1941, with the largest land invasion in history, Operation Barbarossa, as over 3. 8 million Axis soldiers attacked the Soviet Union along a front of roughly 1,800 miles.
The Wehrmacht expected to demolish the country in a 3-month blitzkrieg before winter, and that expectation was not crazy because the USSR was genuinely vulnerable at that moment. Stalin, reassured by the non-aggression pact and naively trusting Hitler’s word, had just finished the Great Purge, the systematic elimination of his own undesirable officers, leaving him completely unprepared for what was coming. On the first day of the invasion, the Luftwaffe destroyed around 1,800 Soviet aircraft, most of them on the ground, leaving the Soviets without air defense.
In just one week, German tanks had pushed 250 miles deep into Soviet territory, and Minsk, the capital of Belarus, was taken. By mid-July, they were already dangerously close to Moscow, fueling Hitler’s confidence as he famously said, “We have only to kick in the door and the whole rotten structure will come crashing down.” His motives included the conquest of vast, fertile territories in the East for German settlement, the destruction of communism, and the elimination of what Nazi ideology called Judeo-Bolshevism, because Slavic peoples were considered subhuman and unworthy of life itself.
All of this was not rhetoric but documented policy, as the Commissar Order directed German forces to separate and shoot Soviet political officers immediately upon capture.
Guidelines, officially known as the Jurisdiction Decree, preemptively absolved German soldiers of criminal responsibility for crimes against civilians, and then there were the Einsatzgruppen, mobile killing units that operated behind the front lines, eliminating Jews, communists, and anyone looking suspicious. By the end of 1941, they had killed over half a million civilians, and that was just the beginning. The Hunger Plan, a name as blunt as it was uncreative, aimed to seize the food supplies of occupied territories for German soldiers and civilians, condemning 20 to 30 million Soviet citizens, particularly the urban population, to starvation.
Estimates suggest that is exactly what happened to at least 4. 2 million people, while prisoners of war were sent into forced labor, starved, or simply shot, with 57 percent not living to see the end of the war. Although the Germans did everything they could to terrorize, oppress, and subjugate the Soviets, they achieved quite the opposite, as all that fanaticism, the merciless destruction and killing of both soldiers and civilians, along with the willingness of the ordinary Soviet soldier to give everything for the homeland, gave rise to partisan groups that posed a serious threat to German forces.
Soviet partisans in Belarus and Ukraine attacked supply lines, sabotaged railways, blew up bridges, ambushed patrols, and coordinated with the Red Army to disrupt enemy logistics every way they could, becoming much more than just a serious headache for the Germans. The Germans responded with collective punishment, including the burning of entire villages, and speaking of fire, both sides carried out a scorched earth policy. The Soviets did it first during their desperate retreat in 1941 under Stalin’s directive to not leave the enemy a single locomotive, not a kilogram of grain, not a liter of fuel, as factories were dismantled and shipped east, crops burned, bridges blown, and entire towns set on fire.
When the tide turned and it was the Germans retreating in 1943 and 1944, they did the exact same thing, burning around 28,000 villages in Ukraine alone and leaving the ancient city of Novgorod in ruins, meaning ordinary people had no food, no shelter, and no way to survive the winter. The winter was brutal, the coldest of the 20th century, with temperatures dropping to 30 degrees below zero, and expecting a quick victory, German soldiers were particularly vulnerable in their summer uniforms, suffering frostbite in massive numbers as losses from the cold sometimes exceeded combat deaths.
When the rains came or the snow started melting, the unpaved roads turned into mud that stopped tanks and supply columns dead in their tracks, and the supply issue was a big one as they moved mostly by train. The German front line required around 120 supply trains per day, but only about 100 were delivered on a good day, and that was before factoring in the different track gauge Russian railways used, which meant German engineers had to relay the tracks before they could run on them at all. On top of that, partisan units were regularly blowing up railway lines, and horses were used for supply transport and pulling artillery, but hundreds of thousands of them died during the winter.
Basic hygiene conditions simply did not exist, as weeks without washing or changing clothes led to a whole range of diseases like dysentery, typhus, and lice running through the ranks, and German soldiers spent months on the front line without relief. Constant fighting, the loss of comrades, and inhuman conditions unsurprisingly led to psychological breakdown, with a special name for it, Russland Kolik, or Russian madness, and it did not help much to find out that their country’s propaganda had been lying to them all along, telling them the USSR was on the verge of collapse.
Soviet men, on the other hand, had it just as bad, as when they were not busy with mass deportations of entire populations, the execution of political opponents, starving prisoners, and much more, they had problems of their own such as the blocking detachments, units positioned behind the front lines with orders to shoot anyone retreating. These were formed under Order 227, suitably named Not One Step Back, and besides shooting deserters, this order meant grouping the disobedient into so-called penal battalions, which were sent on the most dangerous assignments. It was an everyday thing to sentence Soviet soldiers to death in military tribunals for their unwillingness to give their lives in battle, though it hardly mattered since the average life expectancy of a Soviet reinforcement arriving at the front was already measured in hours, not days.
They had their own supply struggles as well, as hunger was a daily reality with rations minimal, and in many cases soldiers were eating leather belts and rats. They did not have enough weapons in the early stages of the war, sometimes two soldiers shared a single rifle, and the one without it waited for his comrade to fall so he could pick it up, while medical supplies and care were equally catastrophic as wounded soldiers often waited hours or days for treatment, and when a surgeon finally reached them, he operated without anesthesia.
Through all of this hardship, exhausted, starving, frozen, and terrified of their own commanders, soldiers on both sides were killing each other in the bloodiest battles in history, and this is no exaggeration. In the Battle of Moscow, which ran from the end of September 1941 until the beginning of January 1942, the Soviets finally managed to prove that the Germans were not invincible after all, as German forces of almost 2 million soldiers of Army Group Center supported by the Luftwaffe came dangerously close to the city trying to push their way in through the defensive lines. What saved Moscow was partly geography, partly winter, and partly the strong morale of the defenders, mostly because of Stalin’s decision to stay and defend the city, as he managed to transfer dozens of divisions and around 1,700 tanks from the Far East, fresh Siberian reinforcements well equipped and more than ready for the counteroffensive.
In the end, although Soviet losses were staggering, somewhere around 1 million casualties, the enemy was left shaken to its core, and while the fighting raged near Moscow, something even more horrifying was happening in Leningrad. From September 1941 until the end of January 1944, the Germans and Finns kept the city surrounded on almost every side, cutting off supplies to both the military and the vast civilian population within, as Hitler had no intention of storming the city but wanted to starve it.
The situation inside quickly became catastrophic, with German artillery pounding the city around the clock, people had to make do with minimal food supplies, and the little bread that was handed out had more sawdust in it than flour. Under constant enemy fire, ships and barges carried food and supplies across Lake Ladoga, the only route available, and in winter, when the lake froze thick enough, trucks drove across this icy path, the so-called Road of Life, sometimes with their lights off to avoid being seen by the enemy, but many broke through the ice and never made it. All those efforts were far from enough, and in the end, Leningrad lost around 1 million lives, more civilians than the United States and Britain lost soldiers combined in the entire Second World War, a third of the city’s population.
Then came Operation Blue, Fall Blau, launched in the summer of 1942, as Hitler directed his offensive toward the Caucasus oil fields and the city of Stalingrad, although splitting your forces to chase two major objectives simultaneously is rarely a good idea. He chose Stalingrad specifically because the city was not just an industrial center but also a symbol of the USSR, given that it bore Stalin’s name, and what followed was the largest, longest, and deadliest urban battle in history. After six months of desperate fighting through every street, every building, every apartment in the city, and after 2 million casualties on both sides, the Germans surrendered, not that they had any other choice anyway, given that their entire Sixth Army was trapped inside the Soviet encirclement.
After the defeat at Stalingrad, Germany made one final attempt to reclaim the initiative on the Eastern Front at Kursk, which would turn out to be the last, as the plan was basically to shorten the front line and destroy as many Soviet forces as possible. However, thanks to the spy network known as Lucy and British intelligence, which had decrypted German communications, the Soviets knew all about it, and the German attack began on July 5th, 1943, immediately running into unexpected layers of defensive positions packed with half a million mines and reinforced by anti-tank ditches. After eight days of brutal tank fighting and the highest number of aircraft shot down in a single day, Hitler called off the operation, and from that moment on, the Wehrmacht was in constant retreat until the very end of the war.
What followed was the greatest defeat in German military history, the Soviet Belorussian Offensive, Operation Bagration, launched right as the Allies were landing in Normandy, and after two months of heavy fighting, only six of German Army Group Center’s 34 divisions remained. German losses are estimated at around 400,000 soldiers, and the prisoners, some 50,000 of them, were paraded through Moscow to demonstrate Soviet superiority and humiliate the enemy, after which the streets were symbolically washed clean, and then the Red Army reached Berlin. Over 1.
5 million soldiers, 6,000 tanks, and 41,000 artillery pieces were concentrated for the final blow to Germany, and the Soviet artillery barrage opened the battle on April 16th, firing nearly 2 million shells, with the rumble heard hundreds of kilometers away.
On that same day, over 100 searchlights were switched on to blind the Germans, an interesting idea that ended up blinding their own tank crews instead, and the fighting continued through the streets of Berlin, where the whole city became the battlefield. Soldiers were fighting block by block, building by building with SS units, regular Wehrmacht men, Volkssturm militia, and even Hitler Youth teenagers defending the rubble, and after around 300,000 total losses on both sides, including civilians, Berlin surrendered on May 2nd, two days after Hitler’s death. On May 8th, 1945, Germany signed its unconditional surrender, and the war in Europe was over, leaving behind a legacy of unimaginable destruction.
Of the estimated 70 to 85 million deaths in the entire Second World War, around 30 million occurred on the Eastern Front, more than on all other battlefields combined, as the Soviet Union alone lost one in every six of its citizens. Of the 5 million German soldiers killed in the war, 4 million died on Soviet soil, and the Eastern Front holds the record for the highest absolute death toll ever recorded on a single battlefield. Civilians paid an enormous price in this conflict, and it was not until the 1980s that the Soviet Union’s demographic growth turned positive again, as more than 1,700 cities and towns vanished along with tens of thousands of villages.
The economy of Soviet Ukraine was almost completely destroyed, and by liberating Eastern Europe, the Red Army established the Soviet sphere of influence, while Germany and Berlin were divided into occupation zones, sowing the seeds of the Cold War. We now see that the Eastern Front was indeed the deadliest theater of war in human history, but while all of this was happening in Europe, somewhere on the other side of the world, another war was being fought, just as brutal, but in its own way, in the Pacific.
