During the Second World War, the United States and the Soviet Union joined forces to fight against Germany. This made it all the more unexpected when, in late 1944, American pilots began targeting Red Army ground forces positioned near the Serbian city of Niš.
The reasons for this attack remain uncertain, as neither side has ever provided an explanation. Despite this, the Niš Incident is remembered as a notable instance of tragic friendly fire.
A big mistake by the American forces
On November 7, 1944, the Soviet 6th Guards Rifle Corps pushed towards Belgrade, Serbia, aiming to bolster the Hungarian front in the south against possible enemy assaults.
At the same time, the US 82nd Operations Group (82 OG) was delivering air support to the Red Army. However, a huge mistake occurred that day. The Americans were evidently unaware that the Soviets had advanced 100 km beyond their anticipated position. Despite assurances from the US Mediterranean Air Force command that no German forces were near Niš, the 82nd proceeded with an attack.
It appears they mistakenly mistook the advancing Soviet troops for German forces.
Friendly fire dogfight
A group of Lockheed P-38 Lightnings open-fired on the Soviet convoy. It’s unclear how many American aircraft were involved in the attack, but the Red Army quickly retaliated, believing them to be Luftwaffe-flown Focke-Wulf Fw-189 Uhus.
Orders were given to Soviet pilots, based out of the nearby Niš Constantine the Great Airport, to aid in the engagement. Multiple Yakovlev Yak-9 and Yak-3s flew to the area, immediately engaging with the P-38s in an action-filled dogfight. It took some time, but the Red Army aviators eventually identified the white stars on the American fighters and laid off their weapons.
Lasted just 15 minutes
From the ground, the Soviets tried to signal the Americans, indicating that they were mistakenly targeting their own allies. However, for some reason, the Americans missed the signals. It wasn’t until the Soviets displayed the large Red Star on their aircraft that the American pilots realized they were attacking an ally and promptly disengaged.
What came to be known as the Niš Incident lasted only about 15 minutes. Despite its short duration, it was enough time for both sides to lose aircraft.
Reason is still unclear
The exact cause of the Niš Incident remains unclear. The official account claims that American forces mistakenly identified Red Army troops as Germans, but full details are still classified. Some suggest there may have been another motive behind the attack. Considering the heightened tensions between the United States and the Soviet Union at the time, many suspect the incident could have reflected the strained relations between the two nations.
Whether this theory is accurate cannot be confirmed until the information is declassified.
Each side has a different account of the event
Each side maintains their own account of what happened. The number of casualties for each varies, with the Soviets suffering between 31-34 casualties, around 37-39 wounded and 20 cargo trucks burned. The US contends that four Soviet aircraft and two P-38 Lightnings were lost that day, while the USSR claimed the total was actually two Yaks and five P-38s.
