From The Civil War Reminiscences of General M. Jeff Thompson:
Page 107, Note 43 – Union Lt. Col. Samuel Wood…..engaged Thompson near Coldwater Station, 35 miles south of Memphis, on July 24, 1862.
Page 168-169, Note 46. – The ten-gun Confederate ironclad gunboat Arkansas was completed ….in late June. As part of her crew. Gen. Ruggles ordered 126 of Thompson’s former militiamen at Grenada to report to Capt. Isaac N. Brown, commander of the gunboat. ……The records do not indicate that Thompson, then stationed near Senatobia (MS), was directed to accompany them.
Page 171, Note 49 – Thompson arrived in Jackson, Mississippi, on August 3.
Based on these facts, it is unlikely that Thompson would have been in Paris, Missouri on July 29 or 30.
