to fight in the Western style together with schools for training Egyptian officers and factories for manufacturing Western style weapons as the vali did not wish to be dependent upon imported arms. Muhammad Ali's grandson, Ismail the Magnificent, who ruled as the Khedive of Egypt between 1863 and 79 recruited mercenaries on large scale. After Napoleon III made an unfavorable arbitration ruling in 1869 about the share of royalties from the newly opened Suez canal, which cost Ismail 3, 000, 000 Egyptian pounds per year, Ismail came to distrust his French mercenaries, and began to look elsewhere. A number of Italian mercenaries such as Romolo Gessi, Gaetamo Casati, Andreanni Somani, and Giacomo Messedaglia played prominent roles in the Egyptian campaigns in the Sudan. Ismail also recruited British mercenaries such as Samuel Baker and the Swiss mercenaries such as Werner Munzinger. After 1869, Ismail recruited 48 American mercenaries to command his army. General Charles Pomeroy Stone, formerly of the United States Army, served as the chief of the Egyptian general staff between 1870 and 1883. Ismail's Americans went to Egypt largely because of the high pay he offered, through several were Confederate veterans who were barred from serving in post-1865 United States Army. The fact that the Americans in Egyptian service had fought on opposing sides in the Civil War was a source of recurring tension as the antagonism between North and South continued in Egypt. Syrian Civil War The Free Syrian Army claimed the Bashar al-Assad regime recruited mercenaries from Iran, Hezbollah militia and the Iraqi Mahdi Army militia during the Syrian Civil War. The Russian government had approved of the deployment in 2016 of the Wagner Group mercenaries to fight for the Syrian government. The Wagner Group is reported to have played an important role in helping to turn the tide of the Syrian civil war in favor of the government, which in 2015 appeared to be close to collapse. On 7 February 2018, the Wagner Group mercenaries were reported to have attacked an American base in Syria together with a pro-Assad militia in what is known as the Battle of Khasham. Turkey used Syrian mercenaries against the Kurds in Syria. Yemen Civil War Multiple mercenary groups, called Popular Committees, which consists of Yemeni tribes loyal to different factions, were formed by both the Hadi government as well as the Houthi Supreme Political Council in the Yemeni Civil War.
