Odd - the 9th Legion seems to have got a kicking everywhere it went. No, not the same battle. Clearly there are now (at least) three in Britain we know about. The first was in Scotland, where a night attack took place on a fort, the second was when the 9th was reformed and marched North into Scotland, never to be seen again. The third involved Boadicea, who was a warlord(ess) way to the South, who seems to have given the 9th (it's THIRD reformation?) another kicking. 
Reading more about the first attack, it seems to fit very nicely into your Night Combat article, because it succeeded only because it was carried out at night - an advance unit snuck in the fort, opened the gates, and the hordes rushed in. Classic! They appear to have succeeded because the Romans couldn't even get their armour on in time, let alone form up in any sort of defensive phalanx. Interesting.
