Military: Battle
When Ptolemy II Philadelphus expanded the Library of Alexandria, rival claimants in the Diadochi wars eyed Egypt as a prize.
One general — in our timeline it might have been Demetrius of Macedon — prepared a naval assault on Alexandria.
The siege nearly succeeded. Fires broke out near the docks, spreading dangerously close to the district housing the Library.
Only a desperate defense and a sudden storm kept the flames from consuming it. The narrow escape shocked the Mediterranean world.
Scholars realized that if the Library burned, the collective memory of millennia — Egyptian scrolls, Babylonian tablets, Indian sutras, Greek treatises — could vanish in a single night.
