Spitamenes

Spitamenes ambushed and destroyed a Macedonian force under Pharnuches near the Polytimetus River. This was Alexander's first major defeat in Central Asia, killing over 2,000 soldiers and forcing Alexander to change his strategy.

Spitamenes besieged the Macedonian garrison at Maracanda (Samarkand). Alexander sent a relief force which Spitamenes defeated, but the siege was eventually lifted when Alexander approached with his main army.

Spitamenes led a sustained guerrilla campaign against Alexander's forces in Sogdiana and Bactria. He used hit-and-run tactics, cavalry raids, and local support to harass Macedonian supply lines and garrisons for over a year.

Spitamenes was betrayed by his own Sogdian and Massagetae allies, who cut off his head and sent it to Alexander as a peace offering. His death ended organized resistance in Sogdiana, allowing Alexander to consolidate control.
