Why was the siege of Halicarnassus difficult for Alexander the Great?

The siege of Halicarnassus in 334 BCE was a particularly difficult operation for Alexander the Great for several key reasons:

• Strong Defenses: The city possessed formidable natural and artificial fortifications, making it a significant obstacle compared to other cities that had previously opened their gates to Alexander.1
• Strategic Importance: Halicarnassus had been designated as the local military headquarters for the Persian forces, meaning it was well-prepared for a sustained defense.1
• Intense Resistance: The city was defended by forces under the command of Memnon of Rhodes, a capable commander in Persian service. The fighting was severe enough that, at one point, Alexander was forced to send a herald to request the return of the bodies of Macedonian soldiers who had fallen directly in front of the city walls.21

While Alexander eventually succeeded in storming the city, the citadels continued to hold out for another year or two following the initial capture.31
