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. Alexander responded to this problem by first blockading and besieging Tyre for seven months, and then by building a causeway that allowed him to breach the fortifications.
