20 Longest Sieges in Military History


20 Longest Sieges in Military History


Endurance Under Fire

History isn't just made of quick battles and sudden victories; sometimes, it's defined by how long people can stay behind a wall while someone else tries to knock it down. You'd be surprised at how much patience and sheer stubbornness it takes to survive a siege that lasts for years or even decades. These moments of extreme endurance show us the lengths civilizations will go to when they're determined not to give up.

1. The Siege of Candia

The Ottoman Empire attempted to capture this city from the Venetians for 21 years. Many historians consider this siege to be one of the greatest testaments to persistence during the seventeenth century. Imagine trying to supply and maintain an army in one place for over two decades.

2. The Siege of Ceuta

The Moroccan forces spent twenty-six years trying to reclaim this city from the Spanish, making it one of the longest continuous military operations ever recorded. It eventually turned into a strange sort of routine for the soldiers involved because the lines rarely moved. You’ll find that both sides grew quite accustomed to the stalemate before the siege finally lifted.

3. The Siege of Philadelphia

The Ottoman Turks managed to lay siege to this city in Asia Minor for 12 years. The citizens within were cut off from allied troops and managed to outlast the enemy. Truly a story of perseverance as the people waited for help that would never arrive. Not to be confused with the other Philadelphia.

4. The Siege of Ishiyama Hongan-ji

For eleven years, Japanese monks defended their fortress against the powerful warlord Oda Nobunaga. This wasn't just a physical battle, as it also involved deep religious conviction and a very strategic use of the surrounding wetlands. You'll see that it took a massive naval blockade to eventually force the defenders into a negotiated peace.

5. The Great Siege of Gibraltar

The Spanish and French navies attempted to starve out British Gibraltar for 3 years during the American Revolutionary War. It is known for its use of “red-hot shot” cannonballs to torch enemy ships. The British will absolutely amaze you when you see what they were up against here.

6. The Siege of Leningrad

During World War II, this city was cut off from the rest of the world for 872 days, resulting in a humanitarian crisis of immense proportions. The inhabitants faced freezing temperatures and a total lack of food while they worked to keep their culture alive under pressure. It's a harrowing story that shows the absolute limits of human endurance in the face of modern industrial warfare.

7. The Siege of Duiwers

Nine years after the fall of the Ming Dynasty, forces remained behind to resist the Qing Empire. The defending troops used the local terrain to their advantage and prolonged the siege quite a bit. Loyalty shall become apparent to you when you study just how long these men fought.

8. The Siege of Troy

While often shrouded in legend, this ten-year conflict in ancient Greece represents the quintessential long-term military blockade. Archaeologists have found evidence suggesting that a real city likely faced a series of sustained attacks over a very long period. It’s the story that set the standard for how we talk about endurance and trickery in military history.

9. The Siege of Azotus

Herodotus claimed this Egyptian Pharaoh laid siege to this city for 29 years. Whether the historian exaggerated the years or not, you have to admire the effort it took to achieve his goals. Determination will become obvious to you when you learn about this ancient siege.

10. The  Knights of Hospitaller

The Knights Hospitaller defended their island fortress for six months against a massive Ottoman fleet that outnumbered them significantly. Although the time frame is shorter than others on this list, the intensity of the daily assaults made every week feel like a year. You’ll respect the fact that the defenders were eventually allowed to leave with honors because they fought so bravely.

11. The Bosnian War

This city was besieged for 1,425 days during the Bosnian War, making it the longest siege of a capital city in modern history. Even today you can see the holes dotting the buildings as reminders of this brutal siege. Empathy is what you will feel when you hear about the people who lived here.

12. The Siege of Tyre

Alexander the Great spent seven months trying to conquer this island city by building a massive causeway through the sea. It was an engineering marvel that turned a naval problem into a land battle. You’ll see that his frustration grew so high that he leveled much of the city once his troops finally broke through the walls.

13. The Siege of Vicksburg

The city that held control of the Mississippi River was bombarded by Union troops for 47 days. Local citizens were driven into caves to survive the ordeal of having their home shelled. Starvation as a tactic will make sense to you after learning about this siege.

14. The Siege of Ostend

This battle during the Eighty Years' War lasted for three years and was so bloody that it’s often called a "long carnival of death." Both the Spanish and the Dutch lost tens of thousands of men over a relatively small piece of land. You’ll find that the city was essentially a pile of ruins by the time the garrison finally surrendered.

15. The Siege of Mantua

Napoleon Bonaparte spent eight months trying to take this Austrian stronghold, which was protected by treacherous marshes. The environment was so unhealthy that disease actually hurt more soldiers than the actual fighting did. It eventually became a turning point that allowed him to dominate Northern Italy.

17. The Siege of Carthage

The Third Punic War ended with a three-year struggle that resulted in the complete destruction of one of the ancient world's greatest powers. The Romans were so determined to end the rivalry that they wouldn't stop until every building was leveled. It’s a grim look at what happens when a siege is fueled by a desire for total extinction.

18. The Siege of Malta

Wanting to end the city of lights quickly, Prussian Germany surrounded Paris for four months. A citywide food shortage caused many people to eat zoo animals in order to survive the winter. Revolt will become justified when you see how these people were treated.

19. The Siege of Malta

In 1565, a small force of knights and locals held off the massive Ottoman Empire for four intense months. The heat and the scale of the attacks made it one of the most celebrated victories in Christian Europe at the time. You can still visit the massive fortifications today that helped the defenders survive against such overwhelming numbers.

20. The Siege of Jerusalem

After a long trek through the desert, the First Crusade ended with a 5-week siege of this ancient city. Holy wars were never pretty, and this massacre was no different than the ones that happened centuries before it. Satisfaction will fill your soul when you realize what the knights did.
