BLUE ON BLUE INCIDENT

Explanation From Original OP:

Context: The Battle of Karánsebes, was a friendly fire incident in the Austrian army, supposedly occurring during the night of 21–22 September 1788, during the Austro-Turkish War of 1788–1791. Some historians have referred to the battle as “history’s worst friendly fire incident”.

On the march thither, the army was seized with a most unaccountable panic, believed themselves to be threatened by the enemy, fell into disorder, and mistook their own troops from the Sclavonian frontiers for enemies. The regiments fired upon one another looked everywhere for an enemy where in reality there was none, and all attempts on the part of the emperor in person to stop the firing and put an end to the confusion were in vain. He was in fact separated from his suite and wandered about ignorant of his way; it was even supposed that he had been taken prisoner when at length, accompanied by a single individual, he came to Karansebes. A detailed account of the singular story of this night-march and its consequences does not appear to us to belong to the province of general history; it will, however, be found both authentic and complete in the Austrian Military Magazine of 1831.

Other sources include one from 1843, 60 years after the battle. This has made it difficult for some scholars to draw reliable sources and evidence for the detailed account of the battle.

At a minimum, the mere fact of the Ottoman capture of the strategic location, without engaging the Austrians, and with Austrian losses reported in contemporary reports, does suggest some significant friendly fire incident by the Austrian forces.

Traditional Story

The army of Austria, approximately 100,000 strong, was setting up camp around the town. The army’s vanguard, a contingent of hussars, crossed the Timiș River to scout for the presence of the Ottoman army. There was no sign of the Ottoman forces, but the hussars came across a group of Romanian people, who offered to sell schnapps(a type of alcoholic beverage that may take several forms) to the weary soldiers.

Soon afterwards, some infantry crossed the river. When they saw the party going on, the infantrymen demanded alcohol for themselves. The hussars refused to give them any of the schnapps and, still drunk, set up makeshift fortifications around the barrels. A heated argument ensued, and one soldier fired a shot.

Immediately, the hussars and infantry engaged in combat with one another. During the conflict, some Romanian infantry began shouting, “Turcii! Turcii!” ("Turks! Turks!").

The hussars fled the scene, thinking that the Ottoman army’s was soon attacking.

Most of the infantry also ran away; the army comprised Austrians, Romanians, Serbs from the military frontier, Croats, and Italians from Lombardy, as well as other minorities, many of whom could not understand one another.

While it is not clear which one of these groups did so, they gave the false warning without telling the others, who promptly fled.

The situation was made worse when officers, in an attempt to restore order, shouted, “Halt! Halt!” which was misheard by soldiers with no knowledge of German as “Allah! Allah!”. (I couldn’t stop laughing here)

As the hussars fled through the camps, a corps commander, General of Artillery Colloredo, thought that it was a cavalry charge by the Ottoman army and ordered artillery fire.

Meanwhile, the entire camp awoke to the sound of battle. The panic caused by the incident demoralised the Holy Roman Emperor Joseph II to the point that he ordered the army to withdraw.

…….Two days later, the Ottoman army arrived. They discovered dead and wounded soldiers and easily took Karánsebes.

Losses

In determining losses, accounts of this incident do not distinguish between losses that were caused by friendly fire, those that were caused by the Turks, and those that resulted from pillaging by the Austrians or by the local Wallachians.

One account states that the Austrian rear guard suffered 150 casualties.

Another account states that in the days following the incident, 1,000 wounded men were taken to the fortress at Arad. Another source claims that 538 men, 24 jäger, and one officer went missing after the incident, but most returned to duty. Also lost were 3 cannons and the chest containing the army’s payroll.

However, secondary sources give much larger estimates as to the losses of the Austrians.

In his account of the incident, Paul Bernard, author of a 1968 biography of the Holy Roman Emperor Joseph II, made an uncited claim that the friendly fire incident caused 10,000 casualties.

Although Bernard’s account of the war has been dismissed as inaccurate by some sources, they do not specifically touch upon the reliability of the figure of 10,000.

Bernard’s claim of 10,000 casualties has been repeated by some historians, such as Geoffrey Regan and Michael Clodfelter.
