At the end of 1181, Raynald of Châtillon raided south into Arabia, in the direction of Medina, although he did not make it that far. It was probably around this time that Raynald also attacked a Muslim caravan. The kingdom had a truce with Saladin at the time, and Raynald's actions have been seen as an independent act of brigandage; it is possible that he was trying to prevent Saladin from moving his forces north to take control of Aleppo, which would have strengthened Saladin's position. In response, Saladin attacked the kingdom in 1182, but was defeated at Belvoir Castle. King Baldwin, although quite ill, was still able to command the army in person. Saladin attempted to besiege Beirut from land and sea, and Baldwin raided Damascene territory, but neither side did significant damage. In December 1182, Raynald launched a naval expedition on the Red Sea, which made it as far south as Rabigh. The expedition was defeated and two of Raynald's men were actually taken to Mecca to be executed in public. Like his earlier raids, Raynald's expedition is usually seen as selfish and ultimately fatal for Jerusalem, but according to Bernard Hamilton it was actually shrewd strategy, meant to damage Saladin's prestige and reputation.
