Our “execution” this date is of the mob justice variety — said mob being panicked Viennese bracing for Ottoman investiture.
As is generally the case one has many ways to read this particular lynching; at least one victim has even been situated as a trans martyr. John Stoye in his The Siege of Vienna: The Last Great Trial between Cross & Crescent gives us the thread of causation, and it turns out that these two unfortunates owed their death to Vienna’s urban planning.
The military architecture of this period was designed to keep the besieger at a distance as long as possible. The ground in front of the main defences would be cleared of buildings, and even levelled — this was the ‘glacis’; along the outer rim or ‘counterscarp’ of the moat a well-protected walk, the covered way, was constructed — usually of timber spars and palisades — from which detachments of the garrison could command with their fire the open ground in front of them; and the covered way had to be laid out so that they could command it from a number of angles … Attackers on the glacis, those who reached the counterscarp, those even who got as far as the main wall, were all exposed to fire from artillery and marksmen on the bastions …
Clamped within the walls but expanding in numbers, the citizens of Vienna had tried to build upwards. They added an extra storey to some 400 out of 1,100 houses in little more than a century. But inevitably the suburbs also grew, spreading out into the countryside — and in towards the city. By 1680 there were large settlements in Leopoldstadt on the Prater island, by the right bank of the Wien on the east, round the hamlets of Wieden and St Ulrich south and south-west, and on the western side. Particularly here the new building approached very close to the fortifications. The government had over and over again ordered the demolition of dwellings within a given distance of the walls, but to little effect. If a maximum estimate of Vienna’s total population brings it to nearly 100,000 people, a sizeable proportion must have lived in these suburbs, which would in due course give accommodation and protection to a besieging army.
The foremost Ottoman raiders now appeared, and in the distance the smoke of burning villages in the neighbourhood rose skywards. [Vienna military governor Count Ernst Rudiger von] Starhemberg did not dare delay in performing one of his most disagreeable duties: the speedy and forcible clearing of the glacis. Since earlier demolition orders had not been obeyed, he began — on 13 July — to burn down everything in the area outside the counterscarp which would obviously hamper the garrison. Most of all he wanted to clear the ground west of the city, where suburbs came closest to the moat. More smoke rose skywards. The sparks flew. They flew over the walls as far as the roof of the Schotten monastery by the Schottengate, where a fire broke out in the afternoon of Wednesday, the 14th; and it almost altered the course of history. The wind blew sparks against the neighbouring buildings, an inn, and from the inn to a wall of the Arsenal, where supplies of every kind were stored, including 1,800 barrels of powder. Nearby, other powder magazines adjoined the New-gate. If the defence-works here were seriously damaged by explosion, or the stores lost, resistance to the Turks was hardly thinkable. The flames moved along a wooden gallery into the Arsenal. Townsmen and soldiers gathered, there was a muddle about keys which could not be found, but soldiers broke through a door and cleared the points of greatest danger. A hysterical mob, looking on, smelt treason at once and lynched two suspects, a poor lunatic and a boy wearing woman’s clothes. It also destroyed the baggage which an inoffensive mining official from Hungary, then in Vienna, was trying to get out of a second inn near the Arsenal; and it panicked at the sight of a flag flying unaccountably from a roof close to the fire, fearing some kind of a signal to the enemy. More effectively, the wind then veered. Flames swept towards and into aristocratic properties on the other side, away from the Arsenal, and proceeded to burn out the Auersperg palace where the ruins went on smouldering for days. The crisis had passed before the arrival of the Turks; but the danger of yet more fires, set off by Turkish bombs or by traitors and spies inside the walls, was to be a constant nightmare in Vienna later on.
Despite the nightmare, Vienna — scorched glacis, crazed mobs, and all — withstood the siege. It was indeed the siege’s Turkish military commander who was executed for his command failure before the year was out, after failing to complete the conquest.
