Need Help with a Title

I am working on the Sequel to the CSS Appomattox. Here is the basic premise of the book.

In this book, Thomas Devareaux is now an airship squadron commander and in direct command of the CSS Greenville. He has been assigned on a goodwill mission to support the British in North Africa.

It just so happens that there is trouble brewing in North Africa among the locals. Devareaux must deal with the British Colonial office who don't want him, crewmen who are rebelling, the Dervish armies of the Mahdi and a mysterious stranger from a hostile European power.

It is set shortly before the fall of Khartoum in 1885 and the subsequent death of General Gordon. I am having difficulty coming up with a working title. What I have so far is "Last Airship from Khartoum: A Thomas Devareaux Alternative History Military Adventure."

The last part is the subtitle which is purely there to contain keywords to drive Amazon search traffic. I think it is cheesy but unfortunately it actually works. So the terrible subtitle will probably stay. But what about "Last Airship from Khartoum?" Does that work?
