Within A.C. Richards' account of what he saw/heard at Ford's is the following:
"The next instant, Mrs. Lincoln appeared at the front of the box, and, with hands upward and downward in great excitement called out something which I did not understand; but I recognized the word, “Guerrillas.” Of course I knew then that something serious has happened, but what, I did not know at that instant."
Bill, you win best wishes for a wonderful holiday weekend.
