General of the Cavalry (General der Kavallerie) was a rank in the Imperial Army of the Holy Roman Empire, Imperial Army of the Austrian Empire, and Imperial Army of the Austro-Hungarian Empire. In 1908, it was approximately equivalent to a United States Army lieutenant general, and usually commanded either a corps or an army. It was one rank below Feldmarschall until September 1915 when the rank of Generaloberst was introduced. It was equivalent to the ranks of General der Infanterie (introduced in 1908 for infantry officers), and Feldzeugmeister (for artillery and engineer officers). Prior to 1908, infantry officers also used the rank of Feldzeugmeister. The next lower rank was Feldmarschallleutnant (usually a divisional commander), which is often rendered as Feldmarschall-Leutnant.
