The four corps were the _Spahis_ in the narrower sense, often called _Spahi-Oghlans_; the _Silihdars_, or weapon-bearers; the _Ulufajis_, or paid troops, in two divisions, the left and the right; and the _Ghurebas_, or Foreign Legion, also in two divisions, the left and the right.[329] The _Spahis_ were most honored and best paid, but each had to bring with him to war five or six armed slaves on horseback. The _Silihdars_ had less pay and furnished four or five horsemen. The _Ulufajis_ furnished two or three horsemen each.[330] These three corps were recruited from the pages and the Janissaries, the _Ulufajis_ receiving also occasional members by special promotions from the irregular troops.[331] The Foreign Legion had least pay of all, and its members came alone; not having begun as the sultan’s _kullar_, and often not even as Ottomans, they enjoyed small honor.[332] Each of the first two corps, and each division of the last two corps of the _Spahis_ of the Porte, was organized separately after the fashion of the Janissaries, with its own general, who supervised the administration of all its affairs.[333] The number of the _Spahis_ of the Porte is given on two bases. In Suleiman’s time the actual members of the four corps counted from ten to twelve thousand men, or a little less than the number of the Janissaries;[334] but, since most of them had each to bring from two to six additional horsemen, the total force which they assembled was from forty to fifty thousand.[335] Whether the entire number or only the actual members were regularly considered to be the sultan’s _kullar_, under his pay, does not appear clearly. Probably he did not pay the additional horsemen directly; for strictly speaking, they were _kullar_ of his _kullar_. In time of battle all the regular troops, _Spahis_ and Janissaries alike, were drawn up to protect the sultan, the Janissaries being aligned in front, the _Spahis_ proper on the right, the _Silihdars_ on the left, and the _Ulufajis_ and _Ghurebas_ in the rear.[336] THE FEUDAL SPAHIS[337]
