I am privy to the research done by the author, he suggested that de Corcuera had a pivotal role in the development of the FMA. consider these facts:
1.) The recruiment of a thousands Cebuanos, Pampangos, Ilonggos in de Corcuera's pacification campaign of Mindanao. The earlier assumption made by bogus FMA historians that the warrior arts of the Phillippines was banned is pure fabrication and has no historical basis in fact.
2.) Jesuit priest actively engaged in teaching combat arts to the indios blending an embryonic form of stick fighting and Renaissance rapier fencing. The practice of orascion came frm these priests.
3.) FMA techniques are mostly Spanish terms i.e. - boca y lobo, fraille(priest), crossada (cross), pluma, planchada, etc. Adrew Abrian's Moro-moro Orabes Heneral and Ilustrisimo's combate heneral could be a reference to the Governor General.
4.) most mind boggling of all as intimated to me by Mr. Macachor -
is Don Sebastian's ethnic origin- he came from the Basque region of Northern Spain where they practice a shepherd stick fighting called MAKILA. His enmity with the Spanish Friars must have something to do with ethnic envy. Furthermore, and the Spanish authorities probably were not comfortable with his patronage of the Filipino warrior class during his administration. Thus his subsequent 5 year imprisonment and later posting in the Canary Islands.
I don't think the kali story can muster the same direct evidence as the ones gathered by these CEbuano writers- Mr. Macachor and Dr. Nepangue. Like me these guys are Cebuanos, and how I wish the kali story is true. But historical accuracy is also important to us Cebuanos. This is our cultural legacy. I hope you guys will understand.
