Unfortunately, his sword had successfully found providence in the underarm of the primitive. He hadn't particularly taken into account how crazy these tribal cultures can be, because the man had somehow managed to throw his axe midway through the swing. Normally not much of a problem, but this thing was tremendously heavy and it had been slingshotted straight towards Ansgar's right leg where it smashed in force against he side of his shin and continued forward. 

In any situation with any normal weapon, this wouldn't be much a problem. Maybe a little bruise and maybe a little bleeding, but this axe weighed an inhuman amount. His shin cracked and buckled beneath the weight, as hid his leg. The bone split pretty cleanly and the man could no longer stop the advance of Zande. 

However! 

Ansgar was a trained professional who knew more about fighting than he did about having a normal life, his reaction was pretty fluid. His upper body twisted with the force of Zande's advance and he shoved his left elbow outwards and into the tribal's side. Almost resembling a clumsy judo throw before his weight could no longer be held by his broken leg. The pain was so intense in this moment his eyesight had washed red and his body had moved on its own. Hopefully Zande would be thrown a goodly distance away from his own momentum, but in the off chance he wasn't the pair would land facing eachother on their sides. Ansgar on his right and Zande on his left.
