Outstanding Gonzalo!!! You have presented a well supported response to my comments that clearly shows you are extremely well informed on this topic. All of what you are saying is well placed and answers many questions about the development of weaponry and tactics in these medieval periods, and emphasizes the importance of Spain in the diffusion of these.
I think that you are the one with the key information on this, and I thank you for the detailed presentation which certainly clarifies my own perceptions on this.
I wonder if this information will answer Ariels question

, regardless, thank you very much Gonzalo, you have definitely answered some for me!!
All very best regards,
Jim
