For forty years, Dennis F. Wiles was a beloved ski instructor and tennis pro in the sun-drenched resorts of California and Colorado, a man who charmed celebrities and built a quiet life with his American wife. But on September 11, 1985, the carefully constructed facade of a lifetime crumbled in a San Pedro, California federal office.
The man who had mingled with Hollywood royalty and taught tennis to the wealthy was, in fact, Georg Gärtner, the last known German prisoner of war still at large in the United States, a fugitive who had spent four decades hiding in plain sight from the FBI.
The extraordinary confession that day, prompted by his wife’s ultimatum to finally reveal the truth or lose her forever, ended one of the most remarkable escape stories of the 20th century. It also peeled back the layers of a largely forgotten chapter of American history, when the nation became home to nearly 400,000 enemy soldiers. Gärtner’s surrender was not just the end of a personal odyssey; it was the closing of a massive and complex wartime operation that had swept across the American home front, leaving a legacy of violence, intrigue, and unexpected humanity in its wake.
The flood of German prisoners began in 1943, a direct consequence of Allied military triumphs in North Africa and Sicily. As the Wehrmacht surrendered in droves, the United States found itself the custodian of a vast army of captured soldiers, a logistical challenge of staggering proportions. By 1945, approximately 371,000 German POWs were held on American soil, representing one of the largest populations of enemy soldiers ever detained within the nation’s borders.
The War Department responded with characteristic efficiency, scattering these prisoners across the continent in a network of more than 700 camps that spanned 46 states.
From the rugged peaks of Colorado’s Rocky Mountains to the arid expanses of Arizona’s deserts, the landscape of America was punctuated by these hastily constructed compounds. Major installations like Camp Carson, Fort Robinson, and Camp Papago Park became temporary cities for the enemy, each typically housing between 500 and 3,000 men. Surrounded by double rows of barbed wire and guarded by watchtowers, the camps were models of military order, with long wooden barracks and mess halls arranged in neat, efficient rows.
Only three states—Nevada, North Dakota, and Vermont—remained untouched by this unprecedented influx of foreign soldiers.
The treatment of these prisoners was governed by the Geneva Convention, and American officials took their obligations seriously. This was driven by a combination of genuine humanitarian concern and a stark, pragmatic fear: mistreating German POWs would inevitably trigger brutal reprisals against Allied airmen and soldiers held in German camps. Consequently, prisoners received the same food rations as American GIs, a diet that was, by 1944, significantly more plentiful than what most German civilians were subsisting on.
For those who chose to work, a wage of 80 cents per day in canteen coupons offered access to small luxuries like cigarettes, candy, and beer, creating a strange marketplace where former enemies could purchase comforts from home.
Work was optional but actively encouraged, and it proved vital to a nation strained by war. German prisoners harvested crops in California orchards and Maine potato fields, built roads in Texas, processed food in Ohio factories, and labored in lumber mills across the Pacific Northwest. They filled critical labor shortages left by American men who were fighting overseas, and some became so indispensable that local farmers lobbied to keep them after the war ended.
Yet, life behind the wire was not solely about labor. A surprisingly vibrant cultural life flourished, with prisoners organizing theatrical productions, forming orchestras, and publishing camp newspapers in German.
The most ambitious camps even established what was called the “barbed-wire college,” offering university-level courses taught by fellow prisoners who had been professors in civilian life. These prisoners could earn credits that were later recognized by German universities, a testament to the intellectual resilience of the men held within the fences. Despite the generally humane conditions, the desire for freedom was a constant undercurrent.
Arizona’s Camp Papago Park recorded 25 escape attempts, more than any other facility. Most escapees were recaptured within days, often turning themselves in after discovering the sheer, overwhelming vastness and emptiness of the American landscape they had fled into.
But beneath the surface of orderly camp routine, a darker, more sinister system was at work. Hardcore Nazi prisoners maintained their own brutal code of justice, targeting fellow Germans suspected of collaborating with American authorities. These self-appointed honor courts investigated and condemned those they deemed traitors to the Reich, and they had willing executioners to carry out their sentences.
The violence was not abstract; it was a chilling reality that claimed the lives of several prisoners and sent shockwaves through the POW system, culminating in the largest mass execution on American soil in the 20th century.
On November 4, 1943, Johannes Kunze, a 39-year-old Afrika Korps veteran, was beaten to death in Camp Tonkawa, Oklahoma. His crime was passing notes to the camp doctor during sick call, providing information about his fellow prisoners. In a mockery of justice, 200 German POWs participated in what they called a trial, and five men carried out the execution.
A few months later, at Camp Aiken, South Carolina, Horst Gunther, a 23-year-old locksmith, was strangled by two fellow prisoners who hung his body from a tree to make it appear as though he had taken his own life. American authorities were not fooled, and the perpetrators were quickly identified.
The most notorious case occurred on March 12, 1944, at Camp Papago Park, Arizona. Werner Drechsler, a U-boat veteran who had been cooperating with American interrogators, was beaten and hanged by seven fellow submariners. His body was discovered the following morning, and all seven perpetrators were identified through their own confessions and the testimony of other prisoners.
The trials began immediately, but the executions were delayed. President Franklin Roosevelt and military commanders feared that executing German POWs would trigger reprisals against Allied prisoners held in Germany, leaving the condemned men to wait in military prisons as the war raged on around them.
The tension of these cases was palpable, and the escape attempts continued to remind officials that not all prisoners had accepted their fate. On December 23, 1944, 25 German naval officers tunneled 178 feet out of Camp Papago Park’s officers compound, a feat of engineering that had taken months. They had hidden the excavated dirt under a volleyball court, and the breakout went undetected for hours.
However, the Arizona desert proved as effective as any guard. All 25 escapees were recaptured within three weeks, most turning themselves in after discovering that the Salt and Gila Rivers were dry, their grand escape foiled by the unforgiving terrain.
The war in Europe ended on May 8, 1945, but for the men involved in the camp murders, the reckoning was only beginning. Within weeks, the delayed executions resumed. Between July and August of that year, 14 German prisoners were executed at Fort Leavenworth: five for the death of Johannes Kunze, two for killing Horst Günther, and seven submariners for the murder of Werner Drechsler.
Their bodies were buried in the military prison cemetery, a grim footnote to a war that had officially ended months earlier. For the hundreds of thousands of other German prisoners in America, however, the war was far from over; the fight for their future was just beginning.
Repatriation proved to be far more complex than capture. Americans expected to return prisoners quickly after Germany’s surrender, but Allied politics intervened. Wartime agreements had already allocated these men as labor resources for war-damaged nations that demanded compensation for years of occupation and destruction.
The process began in February 1946 when the first ships departed East Coast ports, with prisoners believing they were finally going home to Germany. Many had written letters to families they had not contacted in years, expecting joyful reunions in bomb-damaged but familiar towns. Instead, most discovered they were pawns in a larger geopolitical game.
The first wave involved 130,000 German POWs designated as British-owned, men who sailed across the Atlantic to camps in Britain. These allocations dated back to 1943 agreements when Britain had agreed to house German prisoners captured in American operations. But the majority faced a different and harsher fate.
Nearly 740,000 were transferred to French control and redesignated as “disarmed enemy forces,” a classification that stripped away Geneva Convention protections. France demanded the largest share of German labor, calculating that Germany owed 4 million man-years of work to compensate for French workers forcibly sent to German factories during the occupation.
French officials were uninterested in quick repatriation; they wanted reconstruction workers who would stay until the job was finished. In Britain, German prisoners performed agricultural labor and infrastructure repair until late 1947, with conditions generally matching American standards. British families often developed personal relationships with German workers billeted on their farms, with some prisoners learning English, attending local churches, and being invited to family dinners.
France offered a harsher reality, as German prisoners arrived at camps that lacked adequate shelter, medical care, or winter clothing. They rebuilt destroyed railways, cleared minefields without proper equipment, and reconstructed bombed cities under minimal supervision and maximum danger.
Mortality rates varied dramatically by location and assignment, and the last German POWs remained in French custody until 1948, with some not released until 1949. By then, many had spent four years in captivity, longer than America’s entire participation in the war. When they finally reached Germany, they found a divided country they barely recognized.
The Soviet Union took a different approach entirely, holding German prisoners until 1956 and using them for reconstruction work in territories devastated by the German invasion. The final prisoner train from Soviet captivity arrived in West Germany 11 years after the war ended, a stark reminder of the long shadow cast by the conflict.
Of the 371,000 German prisoners held in America, 477 died in captivity from illness, accidents, and violence. They were buried in military cemeteries from Fort Bliss, Texas to Fort Leavenworth, Kansas, with most graves remaining unmarked and no German families ever traveling to claim their bodies. Yet, thousands of others chose to return to America after the war ended.
Approximately 5,000 former German POWs emigrated to the United States in the post-war years, drawn back by memories of their wartime treatment and opportunities unavailable in devastated Germany. Some married American women they had met during captivity, while others simply preferred American life to the reconstruction struggles at home.
The most remarkable post-war story belonged to Georg Gärtner. On September 21, 1945, four months after Germany’s surrender, the 24-year-old former Africa Corps sergeant crawled under the barbed wire at Camp Deming, New Mexico, and hopped a freight train heading west. His hometown of Schweidnitz in Lower Silesia had fallen under Soviet occupation, and rather than face repatriation to communist rule, he chose to disappear in America.
For 40 years, Gartner lived as Dennis F. Wiles, working as a migrant laborer, dishwasher, and construction worker before settling into careers as a ski instructor and tennis pro in California and Colorado.
He organized celebrity tennis tournaments, mingling with Hollywood stars who never suspected his background. The FBI searched for him periodically but never came close, as he lived quietly, moved frequently, and avoided anything that might require documentation of his past. In 1963, he married Jean Clark, an American woman who knew nothing of his true identity.
For 21 years, she lived with a husband who refused to discuss his background, could not travel abroad, and became agitated whenever she pressed him about his mysterious past. In 1984, she packed her bags and called a taxi, threatening to leave unless he finally told her the truth. That night, Gartner confessed everything.
With his wife’s encouragement, he contacted historian Arnold Kramer at Texas A&M University in September 1985. On September 11, 1985, exactly 40 years after his escape, he surrendered to federal authorities in San Pedro, California. The FBI announced it had no further interest in him, and immigration officials confirmed he would not be deported.
He was invited to become an American citizen. Gartner co-authored his autobiography with Kramer and appeared on television talk shows as a curiosity from another era. In November 2009, at age 89, he was finally naturalized as a United States citizen, and he died on January 30, 2013, in Colorado, having outlived the Reich by nearly 70 years.
Veterans of American POW camps continued returning to visit the small towns where they had spent the war, often bringing their families to see where their American experience began. The camps themselves were long gone, replaced by housing developments and shopping centers. But the men who had lived behind the wire never forgot the country that had treated them, even as enemies, with unexpected dignity.
Gärtner’s story, once a secret he guarded with his life, now serves as a powerful lens through which to view this forgotten chapter, a testament to the complex, often contradictory nature of a nation at war, capable of both immense cruelty and profound humanity.
