The American Trick That Let the 155mm Long Tom Hit Unseen German Guns 14 Miles Away

Enemy shells were falling on a position the Americans had already abandoned. The real battery was still firing from a cemetery. In Tunisia, a dummy position helped draw attacks away from the Long Toms. The published account describes eighteen consecutive days of firing without detection—a remarkable outcome for heavy guns that announced every shot with sound, smoke, and flash. At RED TAB BUREAU, we follow the evidence beyond the barrel. This World War II documentary traces the M1 155mm gun, better known as the Long Tom, through the North African Campaign and into Italy. Its reach depended on the weapon. Making that reach useful depended on people passing the right information to the right place. A target beyond a ridge reached the gun crew through observers, communications, maps, and the fire direction center. Piper L-4 aircraft helped provide eyes beyond the horizon. During Operation Torch, a failure to recognize those same aircraft exposed them to fire from their own fleet. From counterbattery fire near Medjez to Kasserine and Maknassy, we examine what the reports actually recorded: guns withdrawing, vehicles dispersing, and distant targets brought under fire. In the Italian Campaign, the story shifts to worn barrels, replacement tubes, repair crews, and the supply decisions behind sustained firepower. The observation system did not extend the Long Tom’s ballistic range. It helped crews use the range they already had. Concealment helped preserve the opportunity to keep using it.
