I found a reference to this on RAT here

I thought - given the interest generated by the AAR Competition at the moment - that it might be worth posting this precis of a Roman desert outpost's AAR.

Copies were made of dispatches received at the site. One concerns an attack by 60 barbarians on the unidentified praesidium site of Patkoua. The barbarians, we are told, attacked at 2pm and the soldiers fought them off until nightfall, resuming the combat the next day. Civilians, who lived around the praesidium had to shift for themselves during the night. On the first day one soldier was killed, a woman and two children taken off (one of the children was subsequently executed). The casualties of the next day are not known. Antonius Celer, a cavalryman of II Ituraeorum, who took part in the incident made a report on it to his superior, the centurion Cassius Victor; this report was passed on 'to the prefects, centurions, decurions, duplicarii and curatores of the Myos Hormos route'.

Shades of a Roman 'Zulu' perhaps? It's not really in our time period but worth posting nonetheless.
