Salvete

And while I am on the subject of lack of information about the calendars, has anyone any additional information on the Rosalia?

So far all I have really found is that on 10 May and again of 30/31 May a Rosalia of the Standards was conducted in every legion. The standards were gathered around the altar at the center of a military camp and crowned with wreaths of roses. There were similar rites in May conducted at family tombs with wreaths of roses laid. The military rite sounds something like the presenting of the colors as modern military units have. The wreathes of roses to decorate the standards, though, suggests this festival may have been some memorial feast for the legion's fall comrades. I would think that armies back in the imperial period would have some of the same social conditions as today - soldiers away from or even cut off from families and thus making the army their new home and family. Unit identity was important to the legionaries, acknowledging the historical record of their unit. And so they would also retain some identification of themselves with former members of the unit, and I assume some rites to honor those former members who then became Manes who looked after the unit just as Manes became Lares to a family. However, all I have found is the appearance of the festival name in military calendars with no additional information. Has anyone anything to add? It is important to me as I have some of my own fallen comrades whose memories I wish to honor.
