How did Alexander the great manage to attack the city of tyre and island when he didnt have a fleet of ships?

Alexander the great managed to attack the island city of Tyre by constructing a massive causeway, or mole, from the mainland to the island. This ambitious engineering feat allowed his forces to transport siege equipment and troops directly to the city's walls. Despite lacking a fleet, Alexander's determination and innovative tactics enabled him to eventually breach Tyre's defenses after a lengthy siege. The successful assault in 332 BCE showcased his military ingenuity and strategic planning.
