Starry Night Pro 5.0 gives a long total eclipse in Athens on that date about 26 minutes after local noon. The date is also surprising close to accepted date of the Trojan War. The umbra would have just missed Troy, with about 99% of the sun shadowed at peak.
Finding ancient eclipses with modern software is no big deal. The correspondence is provocative, but the association of the eclipse with war may have been a later embellishment.
