War has always tested more than armies; it has tested patience, food supplies, and the will to keep going long after hope seemed reasonable. Some of these standoffs dragged on for years and reshaped entire regions, while others ended in a matter of weeks yet still changed the course of history. Here are 30 sieges that show just how much a surrounded city can endure.
1. Siege of Troy
According to Greek legend, this conflict between Achaean forces and the city of Troy stretched on for roughly a decade, ending only through the trick of the wooden horse rather than a direct assault. Archaeologists have found layers of destruction at the site believed to be ancient Troy, lending some credibility to a prolonged conflict there. Whether or not the full myth is accurate, the story became the founding template for siege warfare in Western literature.
2. Siege of Masada
Roman legions surrounded the mountaintop fortress of Masada in the Judean desert for several months around 73 CE, building a massive earthen ramp to finally breach its walls. According to the ancient historian Josephus, the defenders chose mass suicide rather than surrender when the end became inevitable. The site remains one of the most visited archaeological locations in Israel today.
3. Siege of Vicksburg
Union forces under Ulysses S. Grant encircled this Mississippi River stronghold for about six weeks in the summer of 1863, cutting off food and supplies to both soldiers and civilians. Residents reportedly dug caves into hillsides to escape constant shelling while surviving on meager rations. The city's surrender on July 4 gave the Union full control of the Mississippi and split the Confederacy in two.
4. Battle of Vienna
Ottoman forces had the Habsburg capital nearly encircled in the summer of 1683 before a coalition army arrived to break the siege. Polish King Jan III Sobieski led an enormous cavalry charge that shattered the besieging army in one of the largest cavalry actions in history. The victory marked the end of centuries of Ottoman expansion into Central Europe.
5. Siege of Leningrad
German and Finnish forces surrounded this Soviet city for nearly 900 days during World War II, cutting off almost all food and fuel supplies. Residents endured extreme starvation, and estimates suggest over a million civilians died before the blockade was finally lifted in early 1944. It stands as one of the longest and most devastating sieges of the modern era.
6. Siege of Alesia
Julius Caesar trapped the Gallic chieftain Vercingetorix and his forces inside this hilltop settlement in 52 BCE, building an elaborate double ring of fortifications to hold off both the trapped army and a relief force. The Roman victory effectively ended organized Gallic resistance and secured Caesar's conquest of Gaul. Vercingetorix's surrender became one of antiquity's most recognizable images of defeat.
7. Fall of Tenochtitlan
Spanish conquistador Hernán Cortés and his indigenous allies surrounded the Aztec capital for nearly three months in 1521, cutting off its causeways and fresh water supply. Disease, starvation, and constant fighting eventually broke Aztec resistance under the emperor Cuauhtémoc. The city's fall marked the collapse of the Aztec Empire and the beginning of Spanish colonial rule in the region.
8. Great Siege of Malta
Ottoman forces attempted to seize this strategically vital island from the Knights Hospitaller in 1565, launching wave after wave of assaults over roughly four months. Despite being vastly outnumbered, the defenders held their fortresses until reinforcements arrived and forced an Ottoman withdrawal. The victory is often credited with halting further Ottoman expansion into the western Mediterranean.
9. Siege of Orléans
English forces had besieged this French city for months in 1428 and 1429 when a young Joan of Arc arrived to rally French troops and break the blockade. Her leadership helped turn the tide of the Hundred Years' War in favor of France within just a few days of her arrival. The victory transformed Joan into a national symbol and a key figure in French history.
10. Fall of Constantinople
Ottoman Sultan Mehmed II laid siege to the Byzantine capital for about two months in 1453, using massive cannons to batter down walls that had stood for over a thousand years. The city's fall marked the definitive end of the Byzantine Empire and shifted the balance of power across Europe and the Mediterranean. Constantinople was renamed Istanbul and became the new Ottoman capital.
11. Siege of Jerusalem
Roman legions under Titus surrounded and eventually destroyed Jerusalem in 70 CE after months of brutal fighting, famine, and internal factional violence among the city's defenders. The Second Temple was burned during the final assault, an event still mourned in Jewish tradition today. The destruction scattered much of the Jewish population and reshaped the region for centuries.
12. Siege of Sarajevo
Bosnian Serb forces encircled the Bosnian capital for nearly four years during the 1990s Bosnian War, subjecting residents to relentless shelling and sniper fire. Civilians had to cross open streets under fire just to reach food or water, and thousands died during the ordeal. It became the longest siege of a capital city in modern warfare.
13. Battle of Stalingrad
Soviet and German forces fought street by street over this industrial city for roughly five months in 1942 and 1943, in what became one of the deadliest battles in human history. The eventual Soviet encirclement and destruction of the German Sixth Army marked a turning point on the Eastern Front. Estimates of total casualties from the battle run into the hundreds of thousands.
14. Siege of Khartoum
Sudanese Mahdist forces surrounded this Nile city for nearly a year in the mid-1880s, trapping British General Charles Gordon and his garrison inside. Relief forces arrived just two days after the city finally fell, too late to save Gordon, who was killed in the final assault. His death turned him into a celebrated martyr figure in Victorian Britain.
15. Siege of Yorktown
American and French forces trapped British General Cornwallis and his army in this Virginia port town for about three weeks in the fall of 1781. With no route of escape by land or sea, Cornwallis was forced to surrender his entire force. The victory effectively ended major fighting in the American Revolutionary War.
16. Siege of Baghdad
Mongol forces under Hulagu Khan surrounded and sacked this center of Islamic learning in early 1258 after a siege lasting less than two weeks. The attackers destroyed libraries, irrigation systems, and much of the city's infrastructure, an event many historians consider a turning point for the Islamic Golden Age. Estimates of the death toll vary widely but are believed to be enormous.
17. Siege of Candia
Ottoman forces besieged this Venetian-held city on Crete for an astonishing 21 years, making it one of the longest sieges ever recorded. Repeated assaults and blockades gradually wore down the defenders until the city finally capitulated in 1669. The prolonged struggle drained resources on both sides and drew in support from across Europe.
18. Siege of Acre
Crusader forces spent close to two years besieging this coastal fortress during the Third Crusade, with both sides receiving waves of reinforcements throughout the conflict. Richard the Lionheart arrived partway through and helped push the siege toward its conclusion in 1191. The city's capture became one of the signature achievements of the Crusade.
19. Siege of Tyre
Alexander the Great faced one of the toughest challenges of his campaigns at this island city in 332 BCE, ultimately building a massive causeway across open water to reach its walls. The engineering effort took about seven months, unusually long for a commander known for swift victories. Tyre's fall opened the path for Alexander's continued advance toward Egypt.
20. Siege of Paris
Prussian forces encircled the French capital for over four months during the Franco-Prussian War of 1870 and 1871, cutting off food supplies and forcing residents to eat unusual substitutes to survive. The eventual French surrender contributed to the fall of the Second Empire and the rise of a unified German state. The event also fueled lasting French resentment that shaped decades of European politics.
21. Battle of Megiddo
Egyptian Pharaoh Thutmose III led his army against a coalition of Canaanite rebels in the 15th century BCE, and the resulting siege of the fortified city lasted about seven months. It is considered the earliest battle in history for which detailed written records survive. The location later lent its name to the biblical concept of Armageddon.
22. Siege of Rhodes
Ottoman Sultan Suleiman the Magnificent besieged this island stronghold of the Knights Hospitaller for nearly six months in 1522, deploying a massive invasion force against a small but determined garrison. The knights eventually negotiated a surrender that allowed them to leave with honor rather than face annihilation. They later relocated and would go on to defend Malta decades afterward.
23. Siege of Antioch
Crusader armies spent about eight months besieging this heavily fortified Syrian city during the First Crusade, suffering severe shortages of food along the way. Just after finally capturing the city in 1098, the crusaders themselves were besieged by a relieving Muslim army, forcing them to fight on two fronts. Their eventual victory became one of the most dramatic episodes of the entire campaign.
24. Siege of Syracuse
Roman forces besieged this Sicilian city for roughly two years in the late third century BCE, held back in part by defensive machines designed by the mathematician Archimedes. Despite the ingenious defenses, the city eventually fell in 212 BCE, and Archimedes himself was killed during the chaos of the final assault. His inventions remained legendary examples of applied science in ancient warfare.
25. Siege of Petersburg
Union and Confederate forces settled into nearly ten months of trench warfare around this Virginia rail hub between 1864 and 1865, foreshadowing the static warfare later seen in World War I. The prolonged standoff steadily drained Confederate manpower and resources until the lines finally broke. Its fall led directly to the fall of Richmond and the end of the Civil War days later.
26. Siege of Mafeking
British forces held out against a Boer siege of this South African town for 217 days during the Second Boer War, becoming a major news story back in Britain. The garrison, aided by young cadets organized under Robert Baden-Powell, managed to hold on until a relief column finally arrived in 1900. The event later influenced Baden-Powell's founding of the Scouting movement.
27. Siege of Khe Sanh
U.S. Marines held this remote combat base in Vietnam against a prolonged North Vietnamese siege lasting around 77 days in early 1968. Intense artillery bombardment and close combat made it one of the most closely watched battles of the war back home. Debate continues among historians over whether the siege was a genuine strategic threat or a diversion from the larger Tet Offensive.
28. Siege of Ceuta
Moroccan forces besieged this Spanish-held North African city for over three decades starting in the 1690s, making it one of the longest sustained sieges in recorded history. Despite intermittent lulls in fighting, Spanish garrisons managed to hold the fortified city throughout the ordeal. Ceuta remains under Spanish administration to this day, a legacy of that long resistance.
29. Siege of Sevastopol
Allied forces from Britain, France, and the Ottoman Empire besieged this Russian naval base for nearly a year during the Crimean War, marked by brutal trench conditions on both sides. The prolonged campaign became infamous for poor medical care, which spurred reforms championed by nurse Florence Nightingale. The city's eventual fall in 1855 helped bring the war to a close soon after.
30. Battle of Sadr City
U.S. and Iraqi forces effectively besieged this Baghdad neighborhood in 2008, building a massive concrete wall to contain Mahdi Army fighters rather than surrounding an entire city. Weeks of intense urban combat eventually pushed the militia to the negotiating table. The operation illustrated how siege tactics adapted to the realities of modern urban warfare.
