Sixteenth century Europe was ablaze with one war after another. The epoch-defining conflict was the one between the Ottomans and the Hapsburg Empire. This changed European, and Middle-Eastern history. One of this war’s battles included a contingent of Maltese fighting forces. This article explains how they came to be there and the story of that siege.

Background and Origins

For years, there had been tension along the Hapsburg-Ottoman border. Frequent cross-border raids led to a volatile atmosphere on both sides. In July 1593, Grand Vizier Koca Sinan Paşan led raids along the border in present-day Croatia and Hungary. It’s no surprise this exploded into full-scale war.

Prague-based Emperor Rudolf II led the Hapsburg Empire^{1 2}. He held many titles³:

• King of Hungary – His father had given him the crown of Hungary in 1572.
• King of Bohemia – His father granted him the crown of Bohemia in 1575.
• King of the Romans – This was an elected role. It meant he would inherit his father’s imperial title. (The title of Holy Roman Empire was an elective one, it was never inherited⁴.)

Several centuries earlier, one of my ancestors had rejected this title.

He wanted to unify Christendom with a new crusade, seeing himself as the defender of the faith^{5 6 7}. This Ottoman attack was the perfect excuse for him. He secured a Holy League with Pope Clement VIII’s backing. Spain, Transylvania, Wallachia and Moldavia joined in.

This support should have given the Hapsburgs a dominant position. Yet Rudolf’s stubbornness meant he refused to compromise with the Ottomans. This hard-headedness, and his belief in military victory, set the stage for a prolonged war.

Early fighting went against the Christians: The cities of Veszprém and Várpalota fell in 1593, Győr and Komárom in 1594. Reinforced by 2 000 Spanish cavalry and 6 000 infantry, the Hapsburgs crossed the Danube in 1595. They pushed on to Esztergom city, the strongest Ottoman bridgehead north-west of Buda.

The Siege of Esztergom (1595)

Strigonia (Esztergom in Hungarian) is along the Danube between Budapest and Vienna⁸. At the time, the city had a fortress, a walled city and structures along the river⁹. It was also significant as the capital of Hungarian Catholicism¹⁰. Suleiman the Magnificent had captured the city in 1543¹¹. By 1595, Sokolluzade Lala Mehmed Pasha was in control of it¹². The Ottomans had seen off 6 attempts by the Hapsburgs to claim it¹³.

Coalition	Commander(s)	Manpower	War aim
Habsburg Monarchy	Count Karl von Mansfeld; Archduke Matthias	c. 35 000 league troops14 (Imperial, Spanish-Netherlandish, Papal, Saxon, Transylvanian, Croatian)	Recover central Hungary & defend Vienna
(Which included a Maltese–Italian artillery contingent)	General Tommaso Barbara	c. 400 gunners & sappers	Siege artillery for the Imperial army
Ottoman Empire	Kara Ali Bey (Esztergom garrison); Hasan Paşa (relief army)	3 000 in castle; 15 000 – 16 000 relief force from Buda	Hold Danube fortresses; threaten Habsburg core lands

A call to (Maltese) arms

Maltese bombardier General Tommaso Barbara^{15 16} answered Mansfeld’s call for specialist gunners. He had already served in the Spanish army¹⁷ in Flanders¹⁸. Rudolf appointed him¹⁹ Generale dell’Artiglieria²⁰ and promised ennoblement for distinguished service. He marched from Linz with thirty 24-pounder culverins, two giant basilisk guns and a corps of Italian and Maltese pioneers.

On July 1, 1595, Karl von Mansfeld led 35 000 Hapsburg forces to besiege the fortress^{21 22}.

Mansfeld surrounded the fortress on 1 July with three concentric lines. He sited Barbara’s batteries on Castle Hill and the water-town bank. Continuous bombardment cut the water-pipes and silenced most Ottoman cannon within two weeks.

The siege lasted 62 days^{23 24}. The Hapsburgs subjected the city to continuous bombardment and the horror of epidemics²⁵. Further compounding the defenders’ situation, their water reserves didn’t last long²⁶. Rain had replenished the well but this was not enough to serve them all²⁷.

The Ottomans weren’t the only ones suffering.

Hygiene in the Hapsburg camps was a serious problem²⁸. Contemporary regulations established strict sanitary procedures for camp latrines and abattoirs²⁹. This wasn’t enough to prevent outbreaks of disease. As a result of haphazard burial practices and a lack of basic hygiene, an epidemic broke out³⁰.

On 4 August Hasan Paşa’s 15 000-strong relief army advanced from Vörösvár. Mansfeld wheeled two field batteries and 2 000 Spanish cavalry to intercept them on St Thomas’s Hill. Barbara himself faced extreme danger³¹ and directed counter-battery fire that disabled nine Ottoman pieces. He lost his left foot to enemy cannon fire^{32 33}, but he refused evacuation until dusk. Barber-surgeons amputated Tommaso Barbara’s shattered leg in the Imperial camp hospital.

Cut off, short of water and “spiritually broken”, Kara Ali Bey surrundered on September 2^{34 35}. Imperial banners and papal standards replaced the crescents. Rudolf ordered Te Deums from Vienna to Madrid.

It was a short-lived victory; by October 3, the Grand Vizier recaptured the city³⁶.

The Peace of Zsitvatorok

By 1606, faced with a never-ending war, Rudolf’s Hungarian subjects revolted³⁷. This fed concerns about Rudolf’s stubbornness, and his family plotted against him. They convinced him to step aside from Hungary and give it to his brother, Archduke Matthias^{38 39}. By 1606⁴⁰, Matthias finished negotiating with the Ottomans. The war concluded with the Peace of Zsitvatorok on November 11^{41 42}. The treaty established terms for a 20-year peace between the two. Key provisions included⁴³:

• The Ottomans retained the fortresses of Eger, Esztergom, and Kanisza
• Austria received the region of Vác (occupied since 1541)
• A one-time tribute payment of 200,000 florins replaced annual tributes
• Recognition of the emperor as a sovereign of equal rank to the sultan

The treaty confirmed the Ottomans’ inability to penetrate further into Habsburg territory. It also showed that Transylvania remained beyond Habsburg control. This solution favoured negotiated settlement, rather than decisive military victory. It was a pattern that would characterize Habsburg-Ottoman relations throughout the 17th century.

It also established precedents for future diplomatic relations between the two empires⁴⁴. They created a framework for negotiations that would influence Habsburg-Ottoman interactions for generations⁴⁵. This framework stood on two key pillars:

• The establishment of regulated tribute systems.
• The recognition of mutual sovereignty.

As a side note, Europeans captured many manuscripts and books from the battlefield⁴⁶. This led to an engagement with Ottoman literature, practices and education⁴⁷. Vienna led the study of these captured texts, enhancing Europe’s understanding of the enemy⁴⁸.

Tommaso Barbara

On 30 April 1596⁴⁹, Rudolf rewarded General Barbara for his bravery under fire⁵⁰. He bestowed the honorary title of “Noble of Hungary” on Barbara⁵¹ and his descendants^{52 53}. He also granted Barbara the right to bear an eagle above a flaming cannon on a divided shield⁵⁴.

Barbara never returned to active service; he accepted a sinecure as inspector of Imperial foundries at Wiener Neustadt and dictated gunnery notes that circulated among Habsburg artillerymen. He walked with an iron peg-leg until his death in 1612; Maltese tradition venerates him as Il-Ġeneral tall-kanuni (EN: the general of the guns). Barbara retired to the city of Palermo, Sicily, where he died⁵⁵.

Conclusion

Strigonia was a tactical triumph that proved siege-craft and heavy artillery could breach even the strongest Ottoman bastions, and it produced a fleeting surge in Christian confidence. From a tactical point of view, the win was neutral. The Long Turkish War dragged on for another decade and ended in a status-quo. Strategically Rudolf’s obstinate prosecution of the war deepened his fiscal crisis and undermined Habsburg authority in Hungary, sowing seeds of later rebellions.

For the soldiers and townsfolk the battle was unambiguously brutal, leaving a devastated landscape and thousands of wounded. Tommaso Barbara gained nobility but paid with his limb and his career. Strigonia thus stands as a vivid reminder that early-modern “victories” often yielded meagre gains beside immense human and material losses.
