War dance!

[Tollheit]

The Germans also had intimidatory methods. I can't remember the actual name for it, I will look it up for you, but Germanic tribes would emit a unique battle cry, sort of a vocal Mexican wave. This battle cry would start very low and in only certain parts of the battle line, it would then increase in pitch, volume and numbers of participants until it had grown into a full scale deafening roar. Interestingly, and quite possibly as a result of increasing use of Germanic soliders, the later Roman army (4th, 5th century AD) adopted this practice.

It was called 'barritus'. Herwig Wolfram mentions it being used by the Roman army in 377 at the start of a battle against the Tervingi/Visigoths, for example.
