Tishrei 23

In 67 CE, Roman soldiers captured Gamla, a fortress in Israel's Golan region, and killed all its inhabitants. The ancient historian Josephus Flavius, a leader of the Jewish revolt against Rome, fortified Gamla as a main stronghold in 66 CE. The Romans attempted to take the city by means of a siege ramp, but were turned back by the defenders; only on the second attempt did they succeed in penetrating the fortifications and conquering the city. Thousands of inhabitants were slaughtered, while others chose to jump to their deaths from the top of the cliff. The location of ancient Gamla was discovered in archeological excavations during the 1970s; the remains have been preserved as a national park.
