The next year the Spanish Roman Catholic Conquistador Menendez, who later founded St. Augustine, captured and murdered some of the 500+ French civilians, AFTER they surrendered--simply because they refused to convert to Roman Catholicism.
This brutal massacre even shocked Europe at the time, baptizing Roman Catholic history in America in the blood of Protestant Christians.
Most of those captured and murdered by Menendez were French Protestant soldiers and sailors shipwrecked while on their way to attack St. Augustine.
Murdering surrendered soldiers is bad enough without trying to turn them into civilians.
