I'm new here and just saw this thread. I've looked into the First's action on April 6 quite a bit. In his April 30, 1862 report Pfaender stated that the 12 lb Howitzer section was his when it accompanied Sherman on the April 2, 1862 expedition upriver/south and east. While it's possible that he and Peebles switched section commands between April 2 and April 6, that wouldn't make much sense but obviously I don't know for certain. I've seen nothing suggesting that. We do know that Fisher's section contained the two damaged guns that went back to the Landing.. I'm also not sure that the four 6 pounders can be called "James" rifles. Hurter refers to them as "3.67'"" rifles and the bore appears to have been a true 3.67" (rather than 3.8") because the fourth quarter 1862 return for the First shows a supply of 3.67" projectiles (for the two remaining 6 pounder rifles). Another oddity is in William Christie's April 15, 1862 letter to his father,. He states that in his left section "Of the men, No. 3 on our gun and No. 1 on the howitzer were shot dead". By referring to "the howitzer", the implication is that the two remaining sections were reconfigured so that each had one rifle and one howitzer. Nothing else in any of the Christie letters, Pfaender's and Hurter's writings, or Clayton's letters refer to this. It strikes me as bizarre to deliberately create that mix of calibers/types and ordnance in a section.
