Battle of the Pelennor Fields
Shippey writes further that prominent at the critical moment of the Battle of the Pelennor Fields, the decisive charge of the Riders of Rohan, is panache, which he explains means both "the white horsetail on [Eomer's] helm floating in his speed" and "the virtue of sudden onset, the dash that sweeps away resistance." Shippey notes that this allows Tolkien to display Rohan both as English, based on their Old English names and words like "eored" (troop of cavalry), and as "alien, to offer a glimpse of the way land shapes people".
