Good. Then we will fight in the shade.

I love that anecdotes can have survived for so long. From Herodotus, Histories, 7.226.

Although extraordinary valor was displayed by the entire corps of Spartans and Thespians, yet bravest of all was declared the Spartan Dienekes. It is said that on the eve of battle, he was told by a native of Trachis that the Persian archers were so numerous that, their arrows would block out the sun. Dienekes, however, undaunted by this prospect, remarked with a laugh, 'Good. Then we will fight in the shade.'
