Now under the command of John of Brienne, as supported by Bohemond IV, the Hungarians moved against Mount Tabor, regarded by the Muslims as impregnable. A battle fought on 3 December 1217 was soon abandoned by the leaders, only to be revisited by the Templars and Hospitallers. Met with Greek fire, the siege was abandoned on 7 December 1217. A third sortie by the Hungarians, possibly led by Andrew's nephew, met disaster at Mashghara. The small force was decimated, and the few survivors returned to Acre on Christmas Eve. Thus ended what is known as the Hungarian Crusade of 1217.
