The _Beylerbeys_ of Rumelia and Anatolia were called out with their troops for every campaign. The eight other _Beylerbeys_ of Suleiman’s time,—those of Karamania, Amasia, Avandole, Syria, Mesopotamia, Egypt, Hungary,[364] and Temesvar,[365]—who had fewer feudal troops at command and more need of them at home, were summoned only when the war was in their region. OTHER BODIES OF TROOPS There were three principal bodies of irregular troops, the _Akinji_ or cavalry, the _Azabs_ or infantry, and the Kurds; besides various smaller groups, such as the descendants of the ancient corps of _Yayas_ and _Mosellems_, who held fiefs of a sort in the oldest _sanjaks_ of the empire, and the _Deli_ or “crazy” company of scouts.[366] The _Akinji_ numbered perhaps thirty thousand in time of peace and were mainly near the European frontier, where they made a living by raiding. They received no pay either in peace or in war, but gathered booty and slaves and hoped for promotion.[367] The _Azabs_ numbered perhaps ten thousand in peace and forty thousand in war.[368] Some of them served in the garrisons and some with the fleet.[369] The number of the _Akinjis_ and _Azabs_ was greatly augmented in time of war by the addition of volunteers, many of whom were criminals and ruffians.[370] The irregular troops were the terror of the invaded lands in war time; for the regular army was held under iron discipline, but these irresponsible creatures carried fire, rapine, and sword over wide areas of country. In time of siege and battle the _Azabs_ were sent forward to break the charge of the enemy, or to aid in filling the moats by their own bodies.[371] Such as lived were rewarded generously; the rest were believed to pass at once by a martyr’s death to heavenly reward.[372] The Kurds lay near the Persian frontier to the number of about thirty thousand. Individuals among the _Akinji_, _Azabs_, and Kurds might hope to become gentlemen through distinguished bravery, by being made _Ulufajis_ among the _Spahis_ of the Porte.[373]
