Alexander and Military Matters/The Siege of Tyre
The Siege of Tyre was a siege of the city of Tyre, a strategic coastal base on the Mediterranean Sea, orchestrated by Alexander the Great in 332 BC during his campaigns against the Persians. The Macedonian army was unable to capture the city through conventional means because it was on an island and had walls right up to the sea. So Alexander blockaded and besieged Tyre for seven months.
Alexander the Great ordered his engineers to use the debris of the abandoned mainland city to build a causeway and once within reach of the city walls, he used his siege engines from both the causeway and his ships to batter and finally breach the fortifications. It is said that Alexander was so enraged at the Tyrians' defense and the loss of his men that he destroyed half the city. According to Arrian, the Tyrian losses were about 8,000, while the Macedonians lost 400. Alexander granted pardon to the king and his family, whilst the 30,000 residents and foreigners taken were sold into slavery.
