When did the Seleucid garrison surrender the Akra in Jerusalem?

The Seleucid garrison, which held the fortified citadel known as the Akra in Jerusalem, finally surrendered in 141 bce.1

While the Maccabees led a successful revolt against Seleucid rule beginning in 167 bce and managed to purify the Temple in 165 bce, the Akra remained under Seleucid control for several years thereafter, serving as a persistent symbol of foreign occupation until its eventual surrender.12
