Yeomanry \Yeo"man*ry\, n.
   A British volunteer cavalry force, growing out of a royal
   regiment of fox hunters raised by Yorkshire gentlemen in 1745
   to fight the Pretender, Charles Edward. The members furnish
   their own horses, have fourteen days' annual camp training,
   and receive pay and allowance when on duty. In 1901 the name
   was altered to {imperial yeomanry} in recognition of the
   services of the force in the Boer war. See {Army
   organization}, above.
