Black: The Birth of Evil
(Auto-generated)

Kara delivered one last salvo.†
Chpt 26 *
He'd made bold statements and fired off thundering salvos, but standing here on the edge of the jungle, with cicadas screeching all around and the hot afternoon sun beating on his shoulders, the notion that the genesis of a worldwide virus attack lay hidden in this abandoned concrete plant struck him as ludicrous.†
Chpt 27

Definitions:

(1) (salvo as in: a salvo from the guns)
a rapid discharge from one or more weapons
(2) (salvo as in: a verbal salvo)
a sudden, forceful attack in words or actions
(3) (meaning too rare to warrant focus)
Much more rarely, a salvo can reference a sudden burst of applause or cheers as in "There was a salvo of approval."

Even more rarely, salvo can reference an excuse or something to make someone feel better about their self-image as when Henry Fielding wrote, "Blifil had nothing more to do than to confirm these assertions; which he did with such equivocations, that he preserved a salvo for his conscience; and had the satisfaction of conveying a lie to his uncle, without the guilt of telling one."
