Chuck Thompson, a Baltimore Colt's and Orioles broadcaster is famous
for coining sayings such as "Ain't the Beer Cold" and "Go to war, Miss
Agnes." The first quote is the title of his memoirs. It's meaning is
clear. However, What does the "Go to War..." quote refer to, what's
its derivation and in what context would Chuck have used it in a
sports broadcast?

Hi,

I am leaving this information as a comment.

In a recent article in the York Daily Record, dated August 6, 2002,
“While vision fades, his voice remains golden” by DAN CONNOLLY:

Chuck Thompson said “Go to War, Miss Agnes” on April 27, 1968, when
Tom Phoebus pitched a no-hitter.

 “He’s done it, the no-hitter. Tommy Phoebus has pitched a no-hitter.
Go to war, Miss Agnes.” — April 27, 1968

Another mention of Chuck Thompson’s saying:

“Chuck was the same way.  He would "go to war Miss Agnes" when
something good happened, but he would be just as quick to criticize if
the Birds were dogging it.”
