1. I can only find two Whitworths mentioned under the command of Pemberton. Gregg was in Pemberton's command and their never mentioned with him.
2. They are accounted for at the time of the Battle of Raymond under the eye of General Hebert, and they were located on the Rivers, were they had been for months.
3. Gregg's mission was a recon in force, he was to break from engagement if it got too heavy, so he was traveling light. There was no reason for Pemberton to risk losing his very valuable weapons on such a mission, where Gregg was not in a position to take on ships or fortified positions.
4. No mention in the O.R. by any side that a Whitworth gun was used at the Battle of Raymond.
5. On May 1st 1863 Sherman on the river near Snyder's Bluff is warning others about the 'Whitworth Bolts' shooting from the bluffs.
6. In early March one Whitworth was used at Fort Pemberton against the Union fleet. The gun crew of this gun was all injured when a shell hit the Whitworth's magazine, taking out fifteen men and the officer in charge. They would have to be replaced. No damage to the gun.
7. A detachment from Bledsoe's Battery did not go with the Battery to Port Hudson in January. They were assigned to a unit that was around the Whitworth's at Snyder's Bluff and maybe even for a time at Fort Pemberton. They maybe the 'Missouri Battery Detachment' mentioned with the big guns brought down from Snyder's Bluff around the 17-18th of May who surely witnessed and maybe were involved with the last Whitworth bursting in the trenches at Vicksburg.
My opinion is there was no Whitworth gun with Bledsoe's Battery at Raymond and there was no Whitworth gun at the Battle of Raymond.
So who's going to tell the Friends of Raymond? People are sending them Whitworth bolts for their displays.
How did this get started?
