― “One of the last untold stories of World War II is also one of the greatest. It’s a story of adventure, daring, danger, and heroics followed by a web of conspiracy, lies, and cover-up.”
― Gregory Freeman, The Forgotten 500: The Untold Story of the Men Who Risked All for the Greatest Rescue Mission of World War II
Most Americans, including those who frequently read about World War II, are likely unaware of Operation Halyard, the heroic mission to rescue downed U.S. airmen from Nazi occupied Serbia during the closing months of the war. This daring operation remained largely unknown for six decades afterward. This is especially surprising given that Operation Halyard was the largest and most successful rescue mission of American aircrews in our nation’s history. Now, drawing on recently declassified documents, author Gregory Freeman brings this heroic mission into the light of day.
After the Allies established bases in Bari and Brindisi in southern Italy during the second World War, they used those bases to bomb targets in southeastern Europe. Starting in 1942, the Allies sought to interrupt production of the Ploeisti oil fields in Romania. These oil fields supplied the German war machine with nearly a third of their fuel supplies—fuel that was needed to continue the war. The missions were hazardous, and the losses were heavy. The route of flights from Italy to Romania flew directly over what is now Serbia, but was then part of Yugoslavia. The airmen were forced to bail out of damaged planes; each of those bombers held ten people. To the great relief of the downed airmen, they were welcomed by the overwhelming generosity of Serbian people located in small, isolated mountain villages. Serbian peasants hid the downed men, at considerable risk to themselves. The crews were fed from the peasants’ meager food supplies and given overnight accommodations before being escorted onward, away from German-occupied areas. Over time, hundreds of crewmen were hidden in these mountain villages. Their next mission was to find a way to get word out that they were still alive and how to get back to their base to fight again.
The mountain villages were also where General "Draza" Mihailovic and his fellow resistance fighters, the “Chetniks,” were active. When the Germans attacked Serbia, Yugoslavia was a monarchy. The government fled and Mihailovich commanded what was left of the Yugoslav Army. He and his men went into the hills and became a resistance unit. As the people of Yugoslavia were facing the ordeals of World War II, they were also involved in a civil war. They were fighting each other as much as they were fighting the Germans. Mihailovich and his men were also fighting Marshal Josip Broz Tito. Mihailović was vehemently anti-communist and wanted to reestablish the Yugoslav monarchy under a democratic framework. Tito’s Partisans were allied with the Soviet Union and envisioned a communist future for Yugoslavia. However, the Allies backed Tito, incorrectly believing erroneous reports that Mihailovich was collaborating with the Nazis.
After decoding a radio message from the downed airmen, the Office of Strategic Services (OSS), which handled the intelligence and special operations of the United States Army during the second World War, sent in four agents. These agents went to ground for months in the Yugoslav countryside. They soon learned that, like the Serbian peasants, Mihailovich and his anti-communist partisans had protected the downed airmen for months. But how were they to get hundreds of airmen out of Yugoslavia? The list of challenges and potential problems seemed endless, not the least of which was to evade capture until the rescue could be organized. The OSS agents and Mihailovich decided that they would build an airfield near the village of Prajani in southwest Serbia, a hilly region not easily accessible to German forces. The airmen, weakened by months with little food, would have to build an airstrip long enough for Douglas C-47s without any real tools, and without detection, in the heart of Nazi-occupied territory. Finally, the C-47s would have to fly in and out over a region held by heavily armed Germans. To keep the weight down on the aircraft using the short runway, the agents decided to carry just 12 men out per mission, meaning there were more than 40 such missions to Italy. Over the course of four months, more than 500 U.S. airmen were airlifted out of Serbia, the largest rescue operation of American airmen in history. Not one airman was lost.
It is truly an amazing story—that the mission was totally successful, without a single loss. And Freeman’s tale is gripping. As it turns out, the airmen were not “forgotten;” it’s their story that was forgotten—at least until now. I thoroughly enjoyed Freeman’s account about this lesser-known chapter of the war. Unfortunately, however, the author seems to have a bias in favor of Mihailovic. He fails to mention crimes that he and the Chetniks committed against Croats and Muslims.
