Dariush had sent two of his generals Artaphernes and Datis on an expedition to add the Aegean islands to the empire and thus preventing Ionians which had revolted in 499 from contacting their Greek motherland. Naxos was added to the empire and the Persian army seized Delos almost immediately and on Aug, 3d Eritrea the capital of Euboea was taken and inhabitants were sent to Elam. On Aug, 7th, after Persians landed in Marathon which was located 25 kilometers east of Athens, the road to Athens was blocked by the Greek army in a defensive location but the Greek did not engage in a battle and the Persian army was too small to conquer Athens. After five days on Aug, 12 Artaphernes and Datis decided to leave early and while they were boarding, the Greek attacked from behind and caused heavy losses on the Persian army and general Datis was killed, but the overall mission was successfully accomplished.
