Battle of Pelusium - Cambyses II of Persia conquers Egypt by painting cats and other animals sacred to the Egyptians on his soldiers' shields.
Diodorus ascribes the erection of the first fort to rebel Assyrian captives in the reign of Sesostris, and Ctesias (Persica) dates it to the time of Semiramis; but Josephus (l. c.), with greater probability, attributes its structure to some Babylonian followers of Cambyses, in 525 BC.
