Battle of the Trench



The Battle of the Trench (غزوة الخندق), also known as the Battle of Khandaq (معركة الخندق) and the Battle of the Confederates (غزوة الاحزاب), was part of the conflict between the Muslims and the Quraysh, where this time the Quraysh took the offensive and advanced on the Muslims, who defended themselves in Medina by digging a trench around their settlement at the suggestion of Salman the Persian. The battle, which took place in 627 and lasted around two weeks, was lightly fought, with the Muslims reported to have suffered five to six casualties and the Quraysh three.

The Quraysh, tired of seeing the Islamic prophet Muhammad continue to raid and plunder their trade caravans despite his defeat at the Battle of Uhud, decided to occupy his city base, Medina. Realizing that they had little military capability as they were only merchants, they negotiated vigorously with the Bedouins to get them to join the campaign. The Banu Nadir, whom Muhammad had previously expelled from Medina, were also part of this effort, to the extent that they offered the Bedouins half of their crops in Khaybar to persuade them to take part. In the end, they reportedly managed to gather a confederate force of 10,000 men (Watt estimates less than 7,500), including Banu Ghatafan, Banu Sulaym, and Banu Asad.

On the other hand, Muhammad, having learned of the impending Quraysh advance, took the advice of Salman the Persian to have his followers make a deep trench to impede their movement. The Jewish tribe of Banu Qurayza assisted with this Muslims' effort by digging the trench and lending them their tools. When the Quraysh approached, they were unfamiliar with this tactic and struggled to get beyond the trench. As the siege gradually dragged on, Muhammad used the time to negotiate secretly with the Banu Ghatafan, sowing distrust among his opponents. After about two weeks, the weather deteriorated and the invading party withdrew.

The battle caused the Meccans to lose their trade to Syria and much of their prestige. Whereas for Muhammad, he was then reportedly visited by Gabriel, who directed him to attack the Banu Qurayza, which led to the slaughter and enslavement of its population by the Muslims.

Name
The battle is named after the "Trench", or khandaq, that was dug by Muslims in preparation for the battle as an act of defense. The word khandaq (خَندَق) is the Arabised form of the Middle Persian word kandag (کندگ; meaning "that which has been dug"). Salman the Persian advised Muhammad to dig a trench around the city. The battle is also referred to as the Battle of Confederates (غزوة الاحزاب). The Qur'an uses the term confederates (الاحزاب) in to denote the confederacy of non-believers and Jews against Islam.

Background
The Islamic prophet Muhammad first preached his new religion, Islam, in his hometown of Mecca. At first he encountered no serious opposition from the people there, and their response to him was simply indifference, until he began to attack their beliefs, causing tension. A few years later, he moved to Medina after successful negotiations with the Banu Aws and the Banu Khazraj to mediate their tribal conflicts, the latter from which his great-grandmother came.

In Medina, Muhammad became fond of raiding and plundering Quraysh trade caravans, causing armed conflict between them. After Muhammad made a large booty after capturing the caravan at Nakhla during a holy month when bloodshed was forbidden by the Pagan convention, he sent troops to Badr to intercept a large trade caravan returning from Gaza. Abu Sufyan, who was leading the caravan, got wind of Muhammad's plan and sent messengers on a swift journey to Medina for help.

The reinforcements camped near Badr, behind a hill not visible from Muhammad's position. After the caravan had escaped, some of them withdrew, but others remained. Muhammad became aware of their presence after he captured their water carrier who was carrying water from the wells of Badr. Muhammad ordered his followers to close all the wells with sand except one for him and the Muslims, forcing the Quraysh to fight over the water and leading to the Quraysh's defeat.

Wanting to regain their honour after the defeat at Badr and tired of Muhammad's attacks on their caravans, the Quraysh sent an army, and a confrontation with Muhammad took place at Uhud. Muhammad's side initially had the upper hand, but then the tables turned, and he fled to Medina. Thinking that this was enough to deter Muhammad, the Quraysh did not pursue him to finish him off. Nevertheless, Muhammad attacked their trade caravans again, making them determined to take over Medina, in part due to the encouragement of the Banu Nadir, whom Muhammad had previously expelled from the city.

The Confederate
Early in 627, the Banu Nadir met with the Quraysh of Mecca. Huyayy ibn Akhtab, along with other leaders from Khaybar, traveled to swear allegiance with Safwam ibn Umayya at Mecca.

The bulk of the Confederate armies were gathered by the Quraysh of Makkah, led by Abu Sufyan, who fielded 4,000-foot soldiers, 300 horsemen, and 1,000–1,500 men on camels.

The Banu Nadir began rousing the nomads of Najd. The Nadir enlisted the Banu Ghatafan by paying them half of their harvest. This contingent, the second-largest, added a strength of about 2,000 men and 300 horsemen led by Unaina bin Hasan Fazari. The Banu Assad also agreed to join, led by Tuleha Asadi. From the Banu Sulaym, the Nadir secured 700 men, though this force would likely have been much larger had not some of its leaders been sympathetic towards Islam. The Banu Amir, who had a pact with Muhammad, refused to join.

Other tribes included the Banu Murra, with 400 men led by Hars ibn Auf Murri, and the Banu Shuja, with 700 men led by Sufyan ibn Abd Shams. In total, the strength of the Confederate armies, though not agreed upon by scholars, is estimated to have included around 10,000 men and six hundred horsemen. In December 626 the army, which was led by Abu Sufyan, marched on Medina.

In accordance with the plan, the armies began marching towards Medina, Meccans from the south (along the coast), and the others from the east. At the same time, horsemen from the Banu Khuza'a left to warn Medina of the invading army.

Muslim defence
The men from Banu Khuza'a reached Muhammad in four days, warning him of the Confederate armies that were to arrive in a week. Muhammad gathered the Medinans to discuss the best strategy of overcoming the enemy. Meeting the enemy in the open (which led to victory at Badr), and waiting for them inside the city (a lesson learned from the defeat at Uhud) were both suggested. Ultimately, the outnumbered Muslims opted to engage in a defensive battle by digging deep trenches to act as a barrier along the northern front. The tactic of a defensive trench was introduced by Salman the Persian. Every capable Muslim in Medina including Muhammad contributed to digging the massive trench in six days. The ditch was dug on the northern side only, as the rest of Medina was surrounded by rocky mountains and trees, impenetrable to large armies (especially cavalry). The digging of the ditch coincided with a near-famine in Medina. Women and children were moved to the inner city. The Medinans harvested all their crops early, so the Confederate armies would have to rely on their own food reserves.

Muhammad established his military headquarters at the hillock of Sala' and the army was arrayed there; this position would give the Muslims an advantage if the enemy crossed the trench.

The final army that defended the city from the invasion consisted of 3,000 men, and included all inhabitants of Medina over the age of 14, except the Banu Qurayza (the Qurayza did supply the Muslims with some instruments for digging the trench).

According to Irfan Shahid, the Muslims adopted the tactic of using trenches from the Persians, possibly via the Ghassanid Arabs who saw their king killed at the Battle of Thannuris in 527 by this tactic. The adopting is reflected in the Arabic word for this battle, khandaq (خندق), which is a borrowing via Aramaic from Pahlavi kandak.

Siege of Medina
The siege of Medina began in January 627 and lasted for 20 nights. Adding in the six days of trench-building, the entire operation lasted 27 days and was contained within a single month (5 Shawwal-1 Dhu al-Qi'dah). Since sieges were uncommon in Arabian warfare, the arriving Confederates were unprepared to deal with the trenches dug by the Muslims. The Confederates tried to attack with horsemen in hopes of forcing a passage, but the Medinans were rigidly entrenched, preventing such a crossing. Both of the armies gathered on either side of the trench and spent two or three weeks exchanging insults in prose and verse, backed up with arrows fired from a comfortable distance. According to Rodinson, there were three dead among the attackers and five among the defenders. On the other hand, the harvest had been gathered and the besiegers had some trouble finding food for their horses, which proved of no use to them in the attack.

The Quraysh veterans grew impatient with the deadlock. A group of militants led by ‘Amr ibn ‘Abd Wudd and Ikrimah ibn Abi Jahl attempted to thrust through the trench and managed to effect a crossing, occupying a marshy area near the hillock of Sala. 'Amr challenged the Muslims to a duel. According to Shia sources, in response, Ali ibn Abi Talib accepted the challenge, and was sent by Muhammad to fight. As Ali went to fight Amr ibn Abd Wudd, Muhammad said about Ali, "He is the embodiment of all Faith who is going to an encounter with the embodiment of all Unbelief."

Both the fighters got lost in the dust as the duel became intense. Finally, the soldiers heard screams which hinted at decisive blows, but it was unclear which of the two was successful. The slogan, 'Allahu Akbar' (God is the greatest) from the dust confirmed Ali's victory. The Confederates were forced to withdraw in a state of panic and confusion. According to Shia sources, Ali allowed Amr's entourage to retreat; Ali never pursued a fleeing enemy.

The Confederate army made several other attempts to cross the trench during the night but repeatedly failed. Although the confederates could have deployed their infantry over the whole length of the trench, they were unwilling to engage the Muslims at the close-quarter as the former regarded the latter as superior in hand-to-hand fighting. As the Muslim army was well dug-in behind the embankment made from the earth which had been taken from the ditch and prepared to bombard attackers with stones and arrows, any attack could cause great casualties.

Banu Qurayza
The Confederates attempted several simultaneous attacks, in particular by trying to persuade the Banu Qurayza to attack the Muslims from the south. From the Confederates, Huyayy ibn Akhtab, a Khaybarian, the leader of the exiled tribe Banu Nadir, returned to Medina seeking their support against the Muslims.

So far the Banu Qurayza had tried their best to remain neutral, and were very hesitant about joining the Confederates since they had earlier made a pact with Muhammad. When Huyayy approached them, their leader refused to allow him entry.

Huyayy eventually managed to enter and persuade them that the Muslims would surely be overwhelmed. The sight of the vast Confederate armies, surging over the land with soldiers and horses as far as the eye could see, swung the Qurayza opinion in the favor of the Confederacy.

News of the Qurayzah's supposed renunciation of the pact with Muhammad leaked out, and Umar promptly informed Muhammad. Such suspicions were reinforced by the movement of enemy troops towards the strongholds of the Qurayza. Muhammad became anxious about their conduct, and realised the grave potential danger the Qurayza posed. Because of his pact with the Qurayza, he had not bothered to make defensive preparations along the Muslims' border with the tribe. The Qurayza also possessed weaponry: 1,500 swords, 2,000 lances, 300 suits of armour, and 500 shields.

Muhammad sent three leading Muslims to bring him details of the recent developments. He advised the men to openly declare their findings, should they find the Banu Qurayza to be kind, so as to increase the morale of the Muslim fighters. However, he warned against spreading the news of a possible breach of the pact on the Qurayza's part, so as to avoid any panic within Muslim ranks.

The leaders found that the pact indeed had been renounced and tried in vain to convince the Qurayza to revert by reminding them of the fate of the Banu Nadir and Banu Qaynuqa at the hands of Muhammad. The findings of the leaders were signaled to Muhammad in a metaphor: "Adal and Qarah". Because the people of Adal and Qarah had betrayed the Muslims and killed them at the opportune moment, Maududi believes the metaphor means the Qurayza were thought to be about to do the same.

Crisis in Medina
Muhammad attempted to hide his knowledge of the activities of Banu Qurayza; however, rumors soon spread of a massive assault on the city of Medina from Qurayza's side which severely demoralized the Medinans.

The Muslims found themselves in greater difficulties by day. Food was running short, and nights were colder. The lack of sleep made matters worse. So tense was the situation that, for the first time, the canonical daily prayers were neglected by the Muslim community. Only at night, when the attacks stopped due to darkness, could they resume their regular worship. According to Ibn Ishaq, the situation became serious and fear was everywhere.

Quran describes the situation in surah Al-Ahzab:

Muslim response
Immediately after hearing the rumors about the Qurayza, Muhammad had sent 100 men to the inner city for its protection. Later he sent 300 horsemen (cavalry was not needed at the trench) as well to protect the city. The loud voices, in which the troops prayed every night, created the illusion of a large force.

The crisis showed Muhammad that many of his men had reached the limits of their endurance. He sent word to Ghatafan, trying to pay for their defection and offering them a third of Medina's date harvest if they withdrew. Although the Ghatafan demanded half, they eventually agreed to negotiate with Muhammad on those terms. Before Muhammad began the order of drafting the agreement, he consulted the Medinan leaders. They sharply rejected the terms of the agreement, protesting Medina had never sunk to such levels of ignominy. The negotiations were broken off. While the Ghatafan did not retreat they had compromised themselves by entering into negotiations with Medina, and the Confederacy's internal dissension had thereby been increased.

At about that point, Muhammad received a visit from Nuaym ibn Masud, an Arab leader who was well-respected by the entire confederacy, but who had, unknown to them, secretly converted to Islam. Muhammad asked him to end the siege by creating discord amongst Confederates.

Nuaym then came up with an efficient stratagem. He first went to the Banu Qurayza and warned them about the intentions of the rest of the Confederacy. If the siege fails, he said, the Confederacy will not be afraid to abandon the Jews, leaving them at the mercy of Muhammad. The Qurayza should thus demand Confederate leaders as hostages in return for cooperation. This advice touched upon the fears the Qurayza had already harbored.

Next Nuaym went to Abu Sufyan, the Confederate leader, warning him that the Qurayza had defected to Muhammad. He stated that the tribe intended to ask the Confederacy for hostages, ostensibly in return for cooperation, but really to hand over to Muhammad. Thus the Confederacy should not give a single man a hostage. Nuaym repeated the same message to other tribes in the Confederacy.

Collapse of the Confederacy
Nuaym's stratagem worked. After consulting, the Confederate leaders sent Ikrimah ibn Abi Jahl to the Qurayza, signaling a united invasion of Medina. The Qurayza, however, demanded hostages as a guarantee that the Confederacy would not desert them. The Confederacy, considering that the Qurayza might give the hostage to Muhammad, refused. Messages were repeatedly sent back and forth between the parties, but each held to its position stubbornly.

Abu Sufyan summoned Huyayy ibn Akhtab, informing him of Qurayza's response. Huyayy was taken aback, and Abu Sufyan branded him as a "traitor". Fearing for his life, Huyayy fled to the Qurayza's strongholds.

The Bedouins, the Ghatafan, and other Confederates from Najd had already been compromised by Muhammad's negotiations. They had taken part in the expedition in hopes of plunder, rather than for personal reasons. They lost hope as chances of success dwindled, uninterested in continuing the siege. The two confederate armies were marked by recriminations and mutual distrust.

The provisions of the Confederate armies were running out. Horses and camels were dying of hunger and wounds. For days the weather had been exceptionally cold and wet. Violent winds blew out the campfires, taking away from the Confederate army their source of heat. The Muslim camp, however, was sheltered from such winds. The enemy’s tents were torn up, their fires were extinguished, the sand and rain beat in their faces and they were terrified by the portents against them. They had already well nigh fallen out among themselves. During the night the Confederate armies withdrew, and by morning the ground was cleared of all enemy forces.

Aftermath: Siege Of Banu Qurayza
Following the retreat of the Confederate army, the Banu Qurayza neighborhoods were besieged by the Muslims. After a 25-day siege of their neighborhood, the Banu Qurayza unconditionally surrendered. When the Banu Qurayza tribe surrendered, the Muslim army seized their stronghold and their possessions for their acts. On the request of the Banu Aus, who were allied to the Qurayza, Muhammad chose one of them, Sa'ad ibn Mu'adh, as an arbitrator to pronounce judgment upon them. Sa'ad, who later died of his wounds from the battle, decreed the sentence, in which some of the men fighters shall be killed and some of their women and children enslaved. Muhammad approved of this decision, and the next day the sentence was carried out.

The men – numbering between 400 and 900 – were bound and placed under the custody of Muhammad ibn Maslamah, while the women and children were placed under Abdullah ibn Salam, a former rabbi who had converted to Islam.

Ibn Ishaq describes the killing of the Banu Qurayza men as follows: Then they surrendered, and the Apostle confined them in Medina in the quarter of d. al-Harith, a woman of B. al-Najjar. Then the Apostle went out to the market of Medina (which is still its market today) and dug trenches in it. Then he sent for them and struck off their heads in those trenches as they were brought out to him in batches. Among them was the enemy of Allah Huyayy b. Akhtab and Ka`b b. Asad their chief. There were 600 or 700 in all, though some put the figure as high as 800 or 900. As they were being taken out in batches to the Apostle they asked Ka`b what he thought would be done with them. He replied, 'Will you never understand? Don't you see that the summoner never stops and those who are taken away do not return? By Allah it is death!' This went on until the Apostle made an end of them. Huyayy was brought out wearing a flowered robe in which he had made holes about the size of the finger-tips in every part so that it should not be taken from him as spoil, with his hands bound to his neck by a rope. When he saw the Apostle he said, 'By God, I do not blame myself for opposing you, but he who forsakes God will be forsaken.' Then he went to the men and said, 'God's command is right. A book and a decree, and massacre have been written against the Sons of Israel.' Then he sat down and his head was struck off.

A lot of scholars have however cast doubt on ibn Ishaq's account and there is no reliable hadith about the exact number of people killed leading some to argue only prominent ones were executed. A number of individuals were spared when various Muslims intervened on their behalf. Several accounts note Muhammad's companions as executioners, Umar and Zubayr ibn al-Awwam in particular, and that each clan of the Aws was also charged with killing a group of Qurayza men.

According to Ibn Ishaq's biography of Muhammad, one woman who had thrown a millstone from the battlements during the siege and killed one of the Muslim besiegers, was also beheaded along with the men. 'Ã'isha, one of Muhammad's wives, is cited as describing the woman as laughing and chatting with her during the massacre, down to the moment her name was called out: "'By Allah,' she said,' that is me.' I said to her 'You poor soul, what is to happen to you?' She said: 'I must be killed.' 'Why?' I asked her. 'For something I did,' she answered. She went away and was beheaded for her acts. By Allah,('Ã'isha adds) I shall never forget her cheerfulness and her great laugh when she knew that she was to be killed.'"

Ibn Asakir writes in his History of Damascus that the Banu Kilab, a clan of Arab clients of the Banu Qurayza, were also killed though this is not accepted by the majority of traditional Islamic historians.

The spoils of battle, including the enslaved women and children of the tribe, were divided up among the Muslims that had participated in the siege and among the emigrees from Mecca (who had hitherto depended on the help of the Muslims native to Medina).

As part of his share of the spoils, Muhammad selected one of the women, Rayhana, for himself and took her as part of his booty. Muhammad offered to free and marry her and according to some sources she accepted his proposal, while according to others she rejected it and remained Muhammad's companion. She is said to have later become a Muslim.

Scholars argue that Muhammad had already decided upon this judgment before the Qurayza's surrender and that Sa'ad was putting his allegiance to the Muslim community above that to his tribe. One reason cited by some for such punishment is that Muhammad's previous clemency towards defeated foes was in contradiction to Arab and Jewish laws of the time, and was seen as a sign of weakness. Others see the punishment as a response to what was perceived as an act of treason by the Qurayza since they betrayed their joint defense pact with Muhammad by giving aid and comfort to the enemies of the Muslims.

Implications
The failure of the siege marked the beginning of Muhammad's undoubted ascendency in the city of Medina. The Meccans had exerted their utmost strength to dislodge Muhammad from Medina, and this defeat caused them to lose their trade with Syria and much of their prestige with it. Watt conjectures that the Meccans at this point began to contemplate that conversion to Islam would be the most prudent option.

Quran
The main contemporary source of the battle is the 33rd Surah of the Quran.

The Sahih al-Bukhari collection also mentions that after the battle, Muslims were to carry out offensive attacks against their enemies:

Muhammad in order to stop the attacks called for a counter-attack against the idolaters, He asserted to his followers before:

Biographical literature
The incident also is mentioned in the historical works by writers of the third and fourth century of the Muslim era. These include the traditional Muslim biographies of Muhammad, and quotes attributed to him (the sira and hadith literature), which provide further information on Muhammad's life. The earliest surviving written sira (biographies of Muhammad and quotes attributed to him) is Ibn Ishaq's Life of God's Messenger written some 120 to 130 years after Muhammad's death. Although the original work is lost, portions of it survive in the recensions of Ibn Hisham and Al-Tabari. Another early source is the history of Muhammad's campaigns by al-Waqidi (d. 823).
