During the spring of 71, Titus set sail for Rome. A new military governor was then appointed from Rome, Sextus Lucilius Bassus, whose assigned task was to undertake the "mopping-up" operations in Judaea. Naturally, he used X "Fretensis" to oppose the few remaining fortresses that still resisted. As part of this, X "Fretensis" took Herodium, and then crossed the Jordan to capture the fortress of Machaerus on the shore of the Dead Sea. Due to illness, Bassus did not live to complete his mission. Lucius Flavius Silva replaced him, and moved against the last Jewish stronghold, Masada, probably in the autumn of 72. He used Legio X, auxiliary troops, and thousands of Jewish prisoners. After his orders for surrender were rejected, Silva established several base camps and a wall of circumvallation completely around the fortress. When the Romans finally broke through the walls of this citadel, they discovered that the Jewish defenders had chosen death with a mass suicide.
