Our first battle with the Early Frankish vs the Huns began with the Franks as the attackers and the Huns the defenders (unusual as the Huns have an aggression of 4, the Franks 3). The terrain type for the Huns was Steppe. The Huns chose a gentle hill, an area of scrub, and a gully.
The Frankish general was fortunate to have enough pips to move his Ostrogoth allies at the right time. The Franks were able to use the scrub to move warbands through to attack the subject infantry, and were able, with good placement, to shoot down a couple Hun light horse. Meanwhile, Attila and the Gepid nobles were still near the gully, perhaps wary of archery fire, & didn't reach the enemy in time to effect anything.
