THE POLISH PRESENCE IN THE SPANISH MILITARY
Autor: Spanish Commission of Military History
This volume of the Polish Military Presence in the Spanish Army is a contribution of a barely explored topic about a nation somewhat removed from our current historiographic projects. Our main goal pursues to present foreign nations in the Spanish military, and certainly the Poles have something to say.
