Never knew that one, sounds amazing
Have you got any links to read? As google is not bringing anything up
Hmm cant seem to find anything on the siege of Tortega, must be a spelling mistake in there perhaps. But even googling the description of said siege nothing is coming up.
Ah, I see the problem. My memory was at fault regarding the name of the city. It was Tortosa, not Tortega. I'm OK with remembering things in English but pretty crap at remembering things that aren't in English.
A new order of chivalry was created for those knights and it's recorded in several different sources. I forget the original name, but the English translation is the Order of the Hatchet. The name comes from the fact that many of the women used small axes as weapons because that was what they had to hand and knew how to use (most of the women were of course commoners and would have owned and used a small axe as a tool for firewood or whatever).
The older references are in Spanish so I have no idea what they say, but I did find an English reference from 1672 that cites an earlier Spanish reference.
I think that there is enough evidence to conclude that it happened. The ennobling would have been legit - the ruling nobleman had the authority to knight a person and courage in battle that had a big effect was a legitimate reason for doing so. It was very rare for a woman to be knighted in her own name in the middle ages (wives of knights gained the title by marriage in some times and places), but it was legal and did happen in a variety of countries.
