Bridging the Gap: The 139th Airborne Engineers in the Tennessee Maneuvers
After months of technical instruction at Camp Mackall, the 17th Airborne Division needed to prove it could operate as a cohesive unit. To do this, the commanders sent the men into a simulated combat environment where the weather proved to be as fierce an enemy as the opposing force.
On February 4, 1944, the 139th Airborne Engineer Battalion loaded onto troop trains in cold and rainy weather, bound for Portland, Tennessee. Arriving the following day, they set up a bivouac area just northwest of the town and spent ten days preparing to participate in six weeks of extensive combined field maneuvers. Spanning 21 counties, these massive Second Army exercises were designed to test combat readiness under real-world logistical constraints.
Operating as part of the "Red Team," the 17th Airborne Division pitted their tactical skills against the rival "Blue Army" in sweeping simulated engagements. To ensure realism in these war games, umpires assessed casualties and damage, with a select group of the 139th's own engineers serving in this referee role.
The environment in Tennessee proved to be incredibly challenging, pushing the men to their absolute physical limits. Following three straight days of torrential downpours, local Nashville newspapers reported the most severe flooding they had seen in years, turning the engineers' bivouac areas into an inescapable swamp. The men battled what the Nashville Banner called the "sticky mud of Middle Tennessee," which bogged down supply trucks and dragged at the clinging wheels of their vehicles. Despite the brutal conditions, the engineers had a massive job to do. They were tasked with erecting and guarding multiple pontoon bridges, first spanning the "usually placid, easily forded Stones River" before advancing to the "treacherous, swirling muddy waters of the Cumberland," operating under darkness and smoke screens to allow the division to seize its beachheads.
Amidst this back-breaking toil, the battalion also underwent a drastic structural change. After one month in the maneuver area, the original Charlie Company was withdrawn and redesignated as the 596th Airborne Engineer Company. On March 2, 1944, they were ordered back to Camp Mackall to join the 517th Parachute Combat Team, which was soon alerted for overseas duty. Just two days later, on March 4, the 597th Airborne Engineer Company, commanded by 1st Lt. Victor D. Filimon, officially joined the battalion as the new Company C.
Meanwhile, troopers universally described the living conditions as miserable, enduring "sodden field rations," sleepless nights, and biting winter winds. The frozen ground was so severe that one division headquarters soldier recalled that hot food went cold before it could be eaten, and the last of the coffee froze solid right in the cup.
Yet, despite the misery, these six weeks of simulated combat proved invaluable. The grueling environment hardened the unit, forcing them to adapt to extreme exposure. Just as the Nashville Banner announced the "Roar of War Machines To End", marking the conclusion of the seventh and final phase of the entire Tennessee Maneuvers, the operations officially ended. On March 24, 1944, the battalion loaded into a motor convoy under cool, bright skies and transferred to Camp Forrest, Tennessee, closing the book on the historic wartime training grounds. Looking back, this muddy, freezing slog helped prepare the 139th and the 17th Airborne Division for the brutal conditions they would eventually face during the Battle of the Bulge.
The 139th proved they could survive the mud and freezing cold, but to be a true Airborne unit, they had to conquer the skies. Next, we’ll dive into the terrifying, often unsung reality of glider training, where the men learned to ride canvas and plywood into combat.
