The Battle of the Trench (غزوة الخندق‎) was a 27-day-long defence by Muslims of Yathrib (now Medina) from Arab and Jewish tribes. The strength of the confederate armies is estimated around 10,000 men with six hundred horses and some camels, while the Medinan defenders numbered 3,000. In the siege of Medina, the Meccans exerted the available strength to destroy the Muslim community. The failure resulted in a significant loss of prestige; their trade with Syria vanished.
