Was Abner Read On the Monongahela or New London When He Was Mortally Wounded?

As I mentioned in the last two posts, there is some question as to which of these two ships Abner Read was on when he was mortally wounded, plus, the Wikipedia article on him has him dying the following day after the wound, July 8, 1863.

The Find-A-Grave site has his dying on July 12, 1863.  Also, he was commanding the USS New London at the time of his death.A page listing Union naval officer deaths accompanying the Find-A-Grave site has Abner Read dying on July 12, 1863 and having been on the USS Monongahela.

The Together We Served site on Melancton Smith has him commanding the USS Monongahela 1862-1863.  (He also commanded the frigate USS Wabash at both Battles of Fort Fisher.)

The USS Monongahela Wikipedia article has that ship, accompanied by the USS New London involved in the July 7, 1863 battle 12 miles below Donaldsonville, Louisiana, in which the Monongahela's new commander, Abner Read, was killed in action.

So, Go Figure.  --Old B-R'er
