In October 1917, during
World War I, the 49th Stationary Hospital was established at Bralos along with rest and recuperation camps for Allied troops. It remained in use until April 1919. Many of the dead from the hospital—chiefly from the
influenza epidemic—are buried in the
Bralo British Cemetery. It contains 101 burials, 95 of which from the
British Commonwealth. Bralos was also the site of fighting between
British Commonwealth troops and the Germans in the
Battle of Thermopylae (1941). On 12 January 1947, 300
Democratic Army of Greece guerrillas, led by
Captain Diamantis, took the Bralos railway station by surprise at 14:00 local time, when the train pulled into the station. The guerrillas destroyed the radios, called on the passengers to get off the train, and separated the civilians from the soldiers. Captains
Stathakopoulos,
Nikolopoulos and gendarme Kastanas resisted the takeover, who were killed in the ensuing exchange of gunfire. The guerrillas sat at the station for an hour and a half, blew up the chimney of the locomotive and set fire to the train, resulting in the burning of two
wagons. They then left in cars, taking with them about 20 captives, various supplies and the station's cash register, and took refuge in Oiti. Both the Army and
Gendarmerie forces pursued them without result. == Demographics ==
