The order went out within hours of the news reaching the 328th Infantry Regiment: no SS troops or paratroopers would be taken prisoner. They would be shot on sight. Other American units in the Ardennes received similar guidance in the days that followed. The rules that had governed American conduct toward prisoners since North Africa were breaking down, and the soldiers who carried those orders into battle were the same men who, less than two years earlier, had been told their enemy was a dangerous but beatable opponent.

Now they knew better, and they knew worse. It had not started that way. When American units landed on the beaches of Morocco and Algeria in November 1942 under Operation Torch, they were placing themselves on a direct collision course with Field Marshal Erwin Rommel’s Afrika Korps. Most of the men coming ashore had never seen combat.

What they knew about Germans came from Hollywood and from Washington. Before shipping out, every soldier was shown a series of propaganda films produced by Frank Capra, the director who would later give the world It’s a Wonderful Life. His seven films, collectively called Why We Fight, told the men exactly what to expect. The Germans, the films explained, were disciplined but misguided, a naturally capable people trapped under a system that had hijacked their abilities.

The message was simple and reassuring: the Americans were facing a dangerous enemy, but one that could be beaten. The men had barely settled into their new war when the weapons began teaching them otherwise. The German MG 42 machine gun earned its nickname from the soldiers who faced it: Hitler’s buzzsaw. The sound of it, the tearing, rapid-fire ripping that was unlike anything American troops had heard before, became one of the defining memories of combat.

Intelligence reports noted that the sound often affected soldiers more than the sight of the weapon itself. One officer summed it up plainly: it was a good, fast gun, but the psychological effect was real. Letters home told a more complicated story than anyone in Washington expected. Some soldiers wrote about their German prisoners with genuine surprise at how ordinary they seemed.

Others stuck to what their training had taught them, drawing a hard line between us and them. The men were trying to reconcile what they had been told with what they were starting to see. As 1943 progressed and American forces prepared to push deeper into Tunisia, the assumptions that had carried them across the Atlantic were about to meet the Afrika Korps head-on. Most of those assumptions would not survive the first week.

On February 14th, 1943, Rommel struck. His target was the Kasserine Pass, a two-mile gap in the Atlas Mountains held by green American troops. The German attack came with surgical precision. Panzer IV and Tiger tanks smashed through positions defended by M3 Stuart light tanks whose guns could not even scratch German armor.

Rommel’s men had spent two years fighting across North Africa. They knew exactly how to coordinate tanks, infantry, and artillery. American units had practiced it in training. The Germans had perfected it under fire.

By February 20th, the situation was catastrophic. American positions collapsed. Units retreated in what quickly became a rout. Equipment was abandoned where it stood.

The 1st Armored Division lost more than half its tanks in two days. Radio communications broke down. Command posts were overrun. The numbers told the story: 6,500 American casualties in four days, 300 killed, 3,000 wounded, 3,000 captured.

Equipment losses were devastating: 183 tanks, 104 half-tracks, 208 guns. German casualties totaled 2,000. Some British officers watching American units stream westward reportedly began calling them our Italians. The humiliation forced immediate changes.

General Dwight Eisenhower fired Major General Lloyd Fredendall and brought in George Patton. Patton arrived to find the II Corps demoralized, questioning everything they thought they knew about war. Letters home from this period reflected a fundamental shift: grudging respect for German skill, mixed with a determination to learn from the disaster. But Rommel himself saw something different.

The attack had succeeded tactically, notes he made afterward acknowledged that American soldiers fought hard once they recovered from the shock. Their equipment was excellent when properly used. Their leadership was learning fast. The Americans, he concluded, would not make the same mistakes twice.

What Rommel could not know was how right he would be. By May 1943, those same Americans were advancing again. The lessons of Kasserine had come quickly. On July 10th, 1943, Operation Husky launched the largest amphibious assault in history up to that point.

American forces hit the beaches of Sicily with new equipment, new tactics, and a new respect for their enemy. The M4 Sherman tanks that replaced the outgunned M3 Stuarts could finally match German armor. More importantly, the men using them had learned to fight the way the Germans fought. The difference was immediate.

Where Kasserine had been chaos, Sicily was coordination. American units moved with a combined arms precision they had practiced but never mastered: tank-infantry cooperation, artillery support, air-ground coordination. The Americans were finally fighting the way the Germans had been fighting all along. The Germans noticed.

In the mountains of eastern Sicily, veteran Wehrmacht units conducted fighting withdrawals that American officers described with grudging admiration. The enemy used terrain, timing, and limited resources to slow a force three times its size. When cornered, German soldiers fought with the same skill and determination Americans had witnessed at Kasserine, but now the Americans understood what they were seeing. Letters home reflected the shift.

Where earlier correspondence had blamed defeats on German luck or superior numbers, soldiers in Sicily wrote about German professionalism. They mentioned captured Wehrmacht manuals that were better than their own. They noted how German prisoners carried themselves: confident, disciplined, unbroken even in defeat. By the time the campaign ended on August 17th, the German and Italian garrison had executed one of the most successful withdrawals of the war, evacuating over 100,000 troops across the Strait of Messina.

American soldiers had won the battle, but they had learned to respect an enemy who could turn defeat into tactical success. That respect for military skill, they were about to discover, was only the beginning. By December 1944, American soldiers thought they understood their enemy. They had learned to respect German tactics and equipment.

They knew the individual German soldier was skilled and disciplined. They were about to discover that respect could coexist with horror. On December 16th, three German armies smashed through the Ardennes Forest. The surprise was complete.

Within hours, entire regiments were cut off or retreating. The next day, December 17th, changed everything. Near the Belgian town of Malmedy, SS troops under Joachim Peiper captured 120 American soldiers from the 285th Field Artillery Battalion. What happened at the Baugnez Crossroads became the deadliest single incident against American POWs in the entire war.

The German unit assembled the prisoners in a field and opened fire with machine guns. Eighty-four Americans died. Some were finished with pistol shots at close range. A handful survived by playing dead and escaped to tell what had happened.

When investigators examined the scene weeks later, they found gunpowder burns on twenty corpses, evidence of execution-style shots to the head. News spread through American units within hours. The 328th Infantry Regiment issued its new orders. Other units received similar guidance.

The Malmedy Massacre changed the rules of engagement for the rest of the war. American attitudes toward German soldiers became more complex, mixing respect for military skill with an awareness of war crimes. That complexity would deepen when they discovered what else had been happening. On April 4th, Americans liberated Ohrdruf, a subcamp of Buchenwald.

Generals Eisenhower, Bradley, and Patton toured the site together. Eisenhower ordered every nearby unit to send representatives. He wanted his men to see what they had been fighting against. Three weeks later, soldiers from the 45th Infantry Division reached Dachau.

They found more than thirty railroad cars filled with bodies and 32,000 prisoners barely alive. Some Americans, seeing what had happened there, shot SS guards who had already surrendered. An investigation followed, but no charges were filed. After Dachau, everything changed.

The men who walked through those camps understood that the war had never been about military skill alone. But what they really thought about their enemy would not be found in any official report. The real story was hidden in a secret facility outside Washington, recorded when no one thought anyone was listening. From 1942 onward, the US Army operated PO Box 1142 at Fort Hunt, Virginia.

High-value German prisoners passed through its gates: U-boat commanders, generals, nuclear scientists. What they did not know was that every conversation was being recorded. The facility was completely bugged. Hidden microphones captured what German soldiers said in barracks, mess halls, even while walking outside.

The recordings revealed what prisoners really thought when they believed they were alone. American interrogators, many of them German Jewish refugees, gathered intelligence without torture. They relied on patience and psychology. Meanwhile, the War Department was running the largest soldier survey in history.

Samuel Stouffer’s team questioned more than half a million American troops about everything from combat stress to enemy attitudes. The results, published in 1949 as The American Soldier, revealed truths that surprised everyone in Washington. Decades later, historians began assembling the full picture. Peter Schrijvers analyzed thousands of letters and diaries.

Paul Fussell, who had served as a twenty-year-old lieutenant, wrote about the gap between official stories and battlefield reality. What they found was a paradox. American soldiers developed genuine respect for German military skill. Letters home praised German engineering and acknowledged the quality of German units.

Even after Malmedy, many veterans distinguished between Wehrmacht soldiers and SS troops. The respect was real, but so was the revulsion. The men who liberated Dachau never forgot what they saw. Some carried photographs for decades to remind themselves why the war had been necessary.

Others refused all contact with anything German for the rest of their lives. These conflicting memories shaped everything that followed: the occupation, the reconstruction, and eventually the alliance with West Germany. NATO required Americans to work alongside former enemies they respected as soldiers but could never fully forgive. The recordings at Fort Hunt stayed classified for sixty years.

When they were finally released in the 2000s, they confirmed what soldiers had written in letters and told in surveys. The enemy they fought was both more capable and more terrible than anyone had expected. The truth was exactly what those first GIs had discovered in Tunisia.

It was complicated.
