The Great Siege of Malta: The Bloodiest Battle of the 16th Century

If you think Game of Thrones has intense battles, you haven’t read about the Great Siege of Malta.

In the summer of 1565, the serene blue waters of the Mediterranean turned red. The Ottoman Empire—the superpower of the age, the conqueror of Constantinople, the terror of Eastern Europe—sent an armada of nearly 200 ships and 40,000 soldiers to capture the tiny island of Malta.

Defending it? Around 8,000 Maltese militia, Spanish soldiers, and just 700 Knights Hospitaller—warrior monks who had sworn to die rather than surrender. What followed was one of the most savage, desperate, and strategically brilliant sieges in human history.

Here is the story of how a few stone walls and a lot of courage changed the course of Western civilization.


The Prize: Why Malta?

Location, location, location. Malta sits almost exactly in the centre of the Mediterranean. Whoever controls Malta controls the sea lanes between the Muslim East and the Christian West—and the trade routes between them. The island was 60 miles from Sicily and the Italian peninsula.

Suleiman the Magnificent, at the height of his power, understood that taking Malta would give the Ottoman fleet a permanent base in the western Mediterranean. From there, the invasion of Sicily and southern Italy was a logical next step. Rome—the spiritual capital of Christendom—was the ultimate prize.

There was also an intensely personal dimension. The Knights Hospitaller had been based in Malta since 1530, after being expelled from Rhodes. They had spent those years raiding Ottoman shipping and launching corsair attacks on Muslim ports. Suleiman had already driven them from Rhodes in 1522. He wanted to finish the job.


The Knights Hospitaller: Who Were They?

The Knights of St. John—formally the Order of St. John of Jerusalem, later the Knights of Malta—began as a medical order caring for pilgrims in the Holy Land. By the 12th century, they had transformed into one of the most formidable military forces in the Mediterranean.

By 1565, their Grand Master was Jean de Valette, a 70-year-old Frenchman who had himself been captured by Ottomans and served a year as a galley slave before ransoming himself. He spoke six languages, was a veteran of multiple sieges, and was precisely the kind of leader a desperate defence required.

The Knights were not ordinary soldiers. They were drawn from the nobility of every major Catholic nation, took vows of poverty, chastity, and obedience, and trained for war from adolescence. They were arguably the finest heavy infantry in Europe—and they were fighting for their survival and the survival of their order.


Fort St. Elmo: The Star of the Show

The Ottomans, commanded by Admiral Piyale Pasha and land commander Mustafa Pasha, made what historians have called a fatal strategic mistake. They decided to attack Fort St. Elmo first.

St. Elmo was a small, star-shaped artillery fort guarding the entrance to the Grand Harbour. The Ottoman commanders estimated it would fall in three to five days. It was simply too small to matter much. They wanted it cleared quickly so their fleet could use the harbour.

They were catastrophically wrong.

The Bombardment: The Ottomans positioned their massive artillery—including basilisks that fired stone balls weighing 150 pounds—on the heights overlooking the fort and began a sustained bombardment. Day after day, thousands of rounds were fired. The walls crumbled and were rebuilt each night. Relief boats crossed the harbour under fire to reinforce the garrison. De Valette refused to abandon the fort even as it became clear it could not ultimately hold.

The Defense: Inside, the Knights and Maltese soldiers used Greek Fire (an incendiary compound that burned on water), primitive flamethrowers called “trumps,” boiling oil, and showers of firepots to drive back the attackers. Human wave assaults by Janissary troops—the Ottoman elite infantry—were repulsed again and again at enormous cost to both sides.

Day after day, the Ottomans launched attacks. Day after day, they were repulsed. The three-to-five day conquest lasted four weeks.

The Fall: When St. Elmo finally fell on June 23rd after 31 days of continuous assault, almost every defender was dead. The Ottoman army had lost approximately 8,000 men taking a fort that contained a few hundred defenders. Mustafa Pasha, surveying the damage, looked across the Grand Harbour at the much larger Fort St. Angelo and reportedly said: “If so small a son has cost us so dear, what price shall we have to pay for the father?”


The Psychological War

The siege was not merely a physical contest. Both sides understood the power of symbolic acts.

The Crosses in the Harbour: After taking St. Elmo, Mustafa Pasha ordered the bodies of the dead Knights to be decapitated, their limbs cut off, and the torsos crucified on wooden crosses. These crosses were then cast into the harbour to drift towards the remaining Christian fortifications.

The Cannonball Response: Grand Master de Valette—now 70 years old, standing on the ramparts under fire—ordered the immediate execution of all Ottoman prisoners held at St. Angelo. Their heads were loaded into cannon and fired back across the harbour at the Ottoman camp.

The exchange was a message: there would be no quarter, no negotiations, no mercy. This was a war of annihilation.

De Valette was not a man of peacetime virtues. He was a man forged for exactly this moment—and he knew it.


The Turning Point

Through July and August, the Ottomans shifted their assault to the remaining forts: St. Angelo, St. Michael, and the fortified town of Birgu (Il Birgu, now called Vittoriosa). Each attack was repulsed, at terrible cost.

By late August, the Ottoman situation had become critical:

  • Disease—dysentery, typhoid, and the relentless summer heat—was killing soldiers faster than the defenders could.
  • Ammunition and supplies were running low.
  • Morale had collapsed. Elite Janissary troops who had conquered vast empires were being held at bay by stone walls and fanatics.
  • A promised relief force from the Ottoman ally, Dragut (the greatest corsair of his age, who had been killed by a cannon fragment in June), never arrived.

When the Gran Soccorso—a Spanish relief force of around 9,000 soldiers—landed on the island in early September, the Ottoman commanders made a fatal error of intelligence. Believing the force was far larger than it was, Mustafa ordered a retreat to the ships.

Malta had held. After 112 days of siege, 30,000 Ottoman casualties, and the near-total destruction of its fortifications, the island was free.


Why It Mattered

The Great Siege of Malta was a turning point in the balance of power between the Ottoman Empire and Christian Europe. It was the first major Ottoman defeat in a generation—and it shattered the myth of Ottoman invincibility that had paralyzed European courts for decades.

Pope Pius IV declared it the greatest event of the century. Charles IX of France reportedly wept. Philip II of Spain, who had dispatched the relief force after agonizing delays, was acclaimed as the saviour of the West.

The psychological impact was at least as important as the military one. When the Ottoman fleet appeared at the Battle of Lepanto six years later, the Christian Holy League stood and fought—and won—in ways that pre-Malta Europe might never have managed.

As Voltaire wrote a century later: “Nothing is better known than the siege of Malta.”


Visiting the Battlefields Today

Malta has the extraordinary advantage of being both small enough to explore entirely in a few days and densely packed with sites directly connected to the siege.

  1. Fort St. Elmo, Valletta: Now the National War Museum, the fort has been substantially rebuilt but retains its star-shaped plan visible from above. You can walk the ramparts where the last defenders fought and died. The walls show traces of cannon damage beneath later restoration. The museum itself covers Maltese military history from the Knights through World War II.

  2. Fort St. Angelo, Birgu: De Valette’s headquarters throughout the siege. It offers the definitive view of the Grand Harbour and allows you to visualize the strategic layout with extraordinary clarity. The distance across the water to where St. Elmo stood—only a few hundred metres—makes the cannon exchange described above feel viscerally real.

  3. Valletta: The entire capital city was built after the siege on the Mt. Sciberras peninsula, on the site of the Ottoman artillery positions, specifically designed to be impregnable. The city plan—a grid of streets on a fortified promontory surrounded by deep ditches—is itself a monument to lessons learned. It was named after Jean de Valette, the old man who refused to die.

  4. The Malta Experience: A well-produced audio-visual presentation in Valletta covering the siege and Maltese history. Useful context before visiting the physical sites.

Practical Tips:

  • Malta is a short flight from most European cities and is a year-round destination.
  • The summer heat (35°C+) makes midday sightseeing exhausting. Visit forts in the morning.
  • The Three Cities (Birgu, Senglea, Cospicua) across the harbour from Valletta reward exploration on foot—their street plans largely unchanged since the siege.
