One of the more unusual units to see action during the Peninsular War were these "Garrochistas"
The Garrochistas were a sort of Andalusian cattlemen that used long lances to prod bulls!
The wore their regional costume of (usually) green jackets, red head scarves, and broad hats. There lances were quite long.
These Garrochistas participated in the defeat and surrender of Dupont's French at Bailen in 1808.
