Athens defeated Persian forces decisively in the <u>Battle of Maratho</u>n despite the numeric advantage of the Persians.
<u>The Persians lost because of their bad strategic choices mostly, like ending most of their fleet around a tiny island</u> and then getting stranded by the Athenian forces which ensued a battle on the shallow waters.
<u>This battle ended the Persian efforts on Greece for a long time until Xerxes, the son of Darius went to fight the Greeks again.</u>
