At least I think so. They are from Moesgaard last summer, the intensety and nature of the battles should be evident as some of them are series.

Battle

Phase 1, Contact and meleeing, people start falling, sometimes the side's tactic is tried here.

2. Chaos, attrition has worn down the lines, holes appeared and exploited, breakthroughs contained. At some point it looses cohesiveness and chaos ensues as one or both lines collapse. The battle become more fluid here with people maneuvering alone or in small groups all over the battlefield trying to kill others by surprise and from behind. Applying one side's tactic may bring this about.

3. Rally, since we do not fight to death, instead of routing, we reorganise, sometimes on the run forwards or in loose groups (only Ask and Ulfhednir can actually perform that feat), and fight in groups again. Sometimes phase 2 lasts till one side is annihilated though.

Should be evident on pictures and of interest to some.
