Fought B.C. 226, between the Spartans, under Cleomenes, and the forces of the Achæan League, under Aratus. The Achæans early gained an advantage, and the Spartans fled, pursued by the light troops. These, however, being unsupported, the Spartans turned and routed them, and then overwhelmed the Achæan hoplites in their turn with enormous slaughter. Melanthias (Sclavonian Invasion). Fought 559, between the Imperial troops, under Belisarius, and the Sclavonians and Bulgarians, under Zabergan, Prince of Bulgaria. The barbarians assailed the Roman lines, but were easily repulsed, and so precipitate was their flight that only about 500 fell. This was Belisarius’ last victory, and it was closely followed by his disgrace and death. Meldorp. Fought 1500, between the Danes, 30,000 strong, under John of Denmark, and the inhabitants of the province of Dithmarsh, which John designed to bring again under Danish rule, after two centuries of virtual independence. The advancing Danes delivered an assault against a small fortified outpost, but were repulsed, and driven in confusion into the surrounding marshes, where over 11,000 perished. Melitene (Persian Wars). Fought 578, between the Imperial troops, under Tiberius, and the Persians, under Chosroes. After a somewhat indecisive battle, at the end of which each side had held its ground, Chosroes, owing to his heavy losses, found it necessary to retire during the night. The battle was, however, signalised by an exploit of a Scythian chief, in command of the Roman left wing, who at the head of his cavalry charged through the Persian ranks, plundered the royal tent, and then cut his way out through the opposing hosts. Memphis (Athenian Expedition to Egypt). This city was captured B.C. 459 by an Athenian fleet of 200 ships, which sailed up the Nile to the assistance of Inaros, who had raised the standard of revolt against Persia. The citadel, however, held out until B.C. 456, when a Persian army, under Megabyzus, defeated the Athenians and drove them out of Memphis. Memphis (Moslem Conquest of Egypt). In 638, Amron, lieutenant of the Caliph Omar, with 8,000 Moslems, invested the city, and after a siege of seven months, in the course of which the besiegers were nearly overwhelmed by the rising of the Nile, the place was taken by assault. On the site of the Moslem encampment were laid the foundations of Old Cairo. Memphis (American Civil War). A river action fought June 6, 1862, between 8 Confederate armed vessels, under Commodore Montgomery, and 10 Federal gunboats, under Commodore Davis. Only one of the Confederate vessels escaped destruction, and Memphis fell. Mensourah (Fifth Crusade),
