Julian\'s heavy cavalry at Strasbourg; cowardice or common-se

[Sardaukar]

It's very difficult to stop group of horses following each other..this did cause several inadvertent cavalry charges in Napoleonic wars etc...I think in one instance it happened twice in same battle to same unit. If I recall right, I read about this in footnotes of Goldsworthy's Roman Army at War. I think he wrote that as one possible reason for defeat of Pompeian cavalry in Pharsalus.
