I recalled a message asking for further information (by Juan Patrón) about the The Royal Military Chronicle some time ago but cannot recall whether he received any responses (nor can I recall the volume sought) but I guess it was about Tarifa. There's some references in the following I think to Skerret - I hope they are of use to Juan (and other contributors)
