Answer
The fall of Athens to Sparta unfolded in 405 BCE, a cataclysmic event in ancient Greek history. Lysander, a renowned Spartan general, played a pivotal role in orchestrating Athens' capitulation. His ingenious ploy involved fortifying Decelea in 413 BCE, a strategic move that severed Athens' access to crucial resources, thus weakening the city's resilience and ultimately hastening its surrender two years later.
