I'm more interested in how the Danes became a Mediterranian power (never seen them further than northern Spain) than in his generals...

And yeah, the guy is not that great, there's nothing there that noone new could learn. However, personally I tend to treat my generals well, so I'd just leave him to tend some godforsaken place. C'mon, give the man a break! There's no reason to burn the little fella just because he isn't Superman..
