The bravest men I ever saw......yeah it got to me too. And, that name for the cannon - "Medical Directors." You know I like that sarcastic sense of humor.
I found another mention of the two cannon in the road from another member of the 14th Indiana, Carroll's brigade. In describing activity of May 5, 1864, Lieut William Landon, wrote to the
Vincennes Western Sun:
"At 4 o'clock a tremendous musketry fire opened, with occasional discharges of artillery directly in our front. In a few moments, out of breath and heated to a perfect glow, we reached Brock's Roads, and piling knapsacks, dashed into the fight, the left of our regiment saving two pieces of artillery directly on the plank-road, that were under a terrible fire from the enemy's sharp-shooters, they having killed all the horses and disabled the cannoniers."
[Letter. Lt. William Landon to Editor Vincennes Western Sun, (Vincennes, IN), dated Mount Pleasant Hospital, Washington, DC, May 18, 1864, reprinted in Indiana Magazine of History, Vol. 34, No. 1 (MARCH, 1938), page 90.]
Maybe I should have just made it a trivia question and let the players find the answer - if its out there.
