Who is this lady?

[RJNorton]

Gene's answer seems logical to me, so I will switch and second his reply.

[Eva Elisabeth]

Yes, a logical and brilliant guess, Gene, but kudos to your original guess, Roger - it is indeed the Shenandoah!

The Shenandoah was purchased by the Confederacy in 1864 for the task to strike at the Union's economy and "seek out and utterly destroy" Union merchant ships in areas yet undisturbed. She would become one of the most feared commerce raiders in the Confederate Navy. She surrendered on the River Mersey, Liverpool, England, on November 6, 1865. Her flag was the last sovereign Confederate flag to be officially furled. The Shenandoah had also fired the last shot of the American Civil War.

During 12 1⁄2 months of 1864–1865 the ship undertook commerce raiding resulting in the capture and sinking or bonding of thirty-eight Union merchant vessels, mostly New Bedford whaleships. The story about her surrender reads like a seafarers' tale:

Since ships are traditionally "shes" - who is she?
   

[RJNorton]

The Wayanda?

[Eva Elisabeth]

Great guess, Roger, but, sorry, not the Wayanda.

[Eva Elisabeth]

Hint #1: It was an US army vessel.

[RJNorton]

The USS Pocahontas?

[Eva Elisabeth]

Another good idea, Roger, but not her either.

Hint #2: You mentioned this ship not too long ago.

[RJNorton]

The Harriet Lane?

[Eva Elisabeth]

Very good again, Roger, but not the "Harriet Lane" either.

Hint #3: Regarding ships are "shes" - think transgender...

[Gene C]

I didn't know Bruce Jenner had a ship named after him.

[Eva Elisabeth]

Hint #4: She was named after a male whom Abraham Lincoln appointed to an office - but you will know the ship for a very different reason.

[Eva Elisabeth]

Hint #5: This question would also qualify for "Assassination Trivia".

[RJNorton]

Even with all the clues, I am still clueless on this one.

[Eva Elisabeth]

Thanks for letting me know - actually you "inspired" me with a guess on another ship.

Hint #6: This vessel was on duty in your very vicinity.
