Here is what I found on Chinicus Maximus. These revolts having been dealt with, Maximinus then crossed back over the Rhine and drove deep into Germany, his troops marauding the country. A decisive battle then was fought in a swamp near the border dividing today's regions of Württenberg and Baden. The emperor is said to have himself been chest-high in the water at times, urging on his men, leading them, despite heavy losses, to a devastating defeat over their enemy. The Alemanni, badly mauled by the Roman forces, would thereafter remain at peace for some time. and https://en.wikipedia.org/wiki/Battle_at_the_Harzhorn Sweet coins guys!
