Indeed, in dire straits or desperate defence, the nissi fought valiantly, and there was less difference in strength and speed between elven-men and elven-women that had not borne child than is seen among mortals.

Edit:
And more specifically, I am reminded of her role in the battle of Alqualonde, as envisioned in the last version of the rebellion of the Noldor, set down in Tolkien's last month of his life:

In Feanor's revolt that followed the Darkening of Valinor Galadriel had no part: indeeed she with Celeborn fought heroically in defence of Alqualonde against the assault of the Noldor, and Celeborn's ship was saved from them.
