Take the following as truth: By the late nineteenth century, these uses of great and small became obsolete, but to go great guns continued to allude to the loudness, forcefulness, and large size of long-ago cannons and still means to `proceed with considerable momentum, to go full steam ahead, at full bore.
Then the following statement: "The expression 'to go great guns' has fallen into obscurity after the nineteenth century." is true, false, or inconclusive?
Answer: False
