Siege warfare is a military tactic in which an enemy army surrounds a castle or fortress and attempts to break in either by physical force or by starving the inhabitants into submission. In other words, it is a nasty ordeal for all involved and it often sports some diabolical tactics.
Here are three sieges from ancient history that show just how nasty things can get.
1. Battle of Jericho (late 17th or 16th centuries BCE)
The siege of Jericho is a well-known story. The Israelites marched around the walls seven times and on the seventh circuit they stopped, the Levites blew into their shofars and the next thing you know the walls came tumbling down, end of story. However, there is an alternative history that wrings more true.

The Israelite commander named Joshua used psychological terror and stealth to bring down the walls of Jericho. In other words, before Joshua mustered his forces on the days preceding the Jericho battle, he sent two men to scout out the area and the city of Jericho like any good commander would.
Once the men were in the city, they went straight to the inn. An inn is a perfect place for a pair of strangers seeking information. The men got lucky when a prostitute by name of Rahab approached them and gave them all the details about the city's security. Afterward, both spies swore to Rahab that she and her family would be spared so long as she left a scarlet cord hanging from her window.
Once the spies returned with the goodies, Joshua assembled his forces and deployed to Jericho, where they would march around the city for seven days. There are two reasons for this. First was to terrorize the city's inhabitants with this bizarre rounding of the city day after day.
Second, was to keep the guards along the wall occupied by watching the army. While this goes on, a number of men would break rank undetected and head to Rahab's window and climb up the scarlet cord. This would go on for six days. After the seventh day came, the Israelite army stopped, the shofars sounded and the men shouted.
This was a signal for the uncertain amount of men staying in Rahab's apartment to attack the city from the inside by taking the main gate and opening it for the Israelites to storm in. Once the Israelites were in, the slaughter begins.
Every man, woman, child — and even livestock — were put to the sword, except for Rahab and her family.
2. The Siege of Baghdad (1258)
In 1258, the massive Mongol army along with many foreign nations under the authority of Prince Hulegu, surrounded the city of Baghdad after conquering much of Iran and northern Iraq. Once the Mongols settled into camp, the destruction began.

The total size of Hulegu's army was roughly between 100,000-150,000 men, probably closer 120,000 total.
On jan. 30, 1258, the Hulegu gave the order to commence the bombardment of the city walls. But there was a problem. The Mongol siege crews had no rocks. The siege train carrying the needed stones was three days journey away.
While the Mongols look for suitable projectiles to throw at the city walls, Hulegu ordered his Mongol archers to fire arrows over the walls with messages attached saying the city's residents would be treated with kindness if they surrender.
While Hulegu sought to end this siege peacefully, Mongol engineers came up empty handed in the catapult rock search. However, not all was lost. Mongol engineers stripped foundation stones from the buildings in the suburbs and uprooted palm trees to use as hasty projectiles, battering the walls of Baghdad (James Chambers, The Devil's Horsemen, 145).
The Caliph quickly sent ambassadors to negotiate peace but Hulegu would not hear the plea and detained them. Hulegu's message was clear, surrender was not enough; it must be unconditional surrender.
While the Caliph continued to send envoys to Hulegu, the Mongols continued to bombard the walls — focusing on the Ajami tower, which was reduced to rubble by Feb. 1. The Mongols would finally break into the city the next day and seized a portion of the eastern wall. However, the battle was far from over and the negotiations continued for another four days. On the 6 February, the bombardment was over but the Mongols remained on the wall until the Caliph surrendered. Hulegu sent another message, this one to the armies of Baghdad. The message told them to lay down their arms and leave their posts.
Seeing the situation was unwinnable by use of arms, the Caliph's advisors advised him to flee. But one man by the name of Ibn Alqami proposed that the best way to end this was for the Caliph to go before Hulegu. Hulegu's terms to the Caliph were simple: turn over his daughter so that he could marry her and recognize Hulegu as the supreme authority.
If accepted, Hulegu would end the siege. The Caliph agreed and his forces marched out thinking they were going to retire to Syria. However, the forces were killed and later the Caliph and his sons were put to death. As for Baghdad, well, the hounds of hell were let loose.
The Armenian historian, Kirakos of Gandzak, wrote about the destruction stating:
Hulegu then ordered the troops guarding the walls to descend and kill the inhabitants of the city, great and small. (The Mongols) organized as though harvesting a field and cut down countless, numberless multitudes of men, women, and children. For forty days they did not stop. Then they grew weary and stopped killing. Their hands grew tired; they took others for sale. They destroyed mercilessly.
However, Hulegu's wife, the senior Khantun (lady), named Doquz Khatun was a Christian. She spared the Christians of Baghdad, Nestorians and other denominations and beseeched her husband not to kill them. And he spared them with their goods and property.
Hulegu ordered all his soldiers to take the goods and property of the city. They all loaded up with gold, silver, precious stones, pearls, and costly garments, for it was an extremely rich city, unequalled on earth.
Hulegu himself took his share the caliph's treasures—three thousand camel loads; and there was no counting the horses, mules and asses.
So how many people died? That answer is disputed. But it has been suggested that as many as 2 million may have been killed in the Mongol destruction. However, this does not take into account the many more that were slaughtered throughout the Near East during Hulegu's military expedition.
3. "Bring out your Dead!" The Siege of Kaffa (1346)
While this is a not ranking list, the Siege of Kaffa probably wins hands down for the suckiest siege. The reason is that Kaffa is ground zero for the worst plague to date to ever fall upon mankind. However, I understand the plague started elsewhere, but for Europe, Kaffa is the main source. So how did it happen?

In 1346, Mongols besieged the Genoese city of Kaffa located on the Black Sea. Before this siege, the Mongols and Genoese made an agreement in 1266 that the city would serve as a trading center between Europe and the Far East. However, the city would be taken over by the Mongols later on only to be given back. This seesaw agreement tradeoff would go on for some time.
The final straw came in 1343 when Christian locals and Muslims in the enclave of Tana inflamed. In turn, the Christians fled to Kaffa to escape the wrath of Khan Janibeg. Janibeg sent his army after them and found them hiding in the city. So what better option than to besiege the city.
In 1344, the Genoese were successful in breaking the siege by killing 15,000 of the Khan's men and destroying their siege engines. The Khan would come back and try again in 1346, but as the Mongol besieged the city, a mysterious illness began to circulate the encampment. The Mongols, seeing their men fall ill and die, decided to use the bodies as a weapon. According to the notary Gabriel de Mussis:
The dying Tartars, stunned and stupefied by the immensity of the disaster brought about by the disease, and realizing that they had no hope of escape, lost interest in the siege. But they ordered corpses to be placed in catapults (trebuchets) and lobbed into the city in the hope that the intolerable stench would kill everyone inside. What seemed like mountains of dead were thrown into the city, and the Christians could not hide or flee or escape from them, although they dumped as many of the bodies as they could in the sea. And soon the rotting corpses tainted the air and poisoned the water supply, and the stench was so overwhelming that hardly one in several thousand was in a position to flee the remains of the Tartar army. Moreover, one infected man could carry the poison to others, and infect people and places with the disease by look alone. No one knew, or could discover, a means of defense.
Eventually, the city would surrender in 1349. But the damage had been done, and some of the Genoese took to their ships heading back for the ports in Italy. Unfortunately, some on board of those ships were infected with the bubonic plague. Gabriel de Mussis mentions this, stating:
…As it happened, among those who escaped from Caffa by boat were a few sailors who had been infected with the poisonous disease. Some boats were bound for Genoa, others went to Venice and to other Christian areas. When the sailors reached these places and mixed with the people there, it was as if they had brought evil spirits with them: every city, every settlement, every place was poisoned by the contagious pestilence, and their inhabitants, both men and women, died suddenly.
Overall, the Siege of Kaffa could be the deadliest siege ever. The outcome of the siege and the bubonic plague affected much of the world, particularly Europe, since Asia was already contaminated.
While it is possible that had the siege at Kaffa not taken place, the plague may not have infected Europe, or it may have come much later. But given that the siege did happen, it may have unwittingly resulted in the deaths of 50 million people out of a population of 80 million in Europe from 1346-1353.
