أحمد باشا الجزار
In 1788, Jezzar Pasha demanded that Emir Yusuf pay off the bribe he had promised him in 1783, but Emir Yusuf refused. Consequently, Jezzar threw his support to Ali Shihab, Isma'il's son, in his bid to eliminate Emir Yusuf, who in turn backed an uprising against Jezzar in Acre. After Jezzar suppressed the revolt, Ali launched an offensive against Yusuf's holding in the Beqaa Valley, but was repelled by Yusuf's brother Haydar. However, Jezzar Pasha arrived to support Ali, and their combined 2,000-strong force moved against Haydar, whose forces after the desertion of the Harfush clan consisted of 700 cavalry from the Shihab and Abi Lamas clans and disgruntled mercenaries of Jezzar. Jezzar Pasha decisively defeated Emir Yusuf at Jubb Janin in south Beqaa.
