Best Book On Foreign Relations / Intervention

[LedgerSko]

I did the old forum search and came up empty. What is the best book out there on foreign relations or possible involvement in the war?

This is what I have found on Amazon.

One War at a Time: The International Dimensions of the American Civil War - Dean Mahin

Guns for Cotton: England Arms the Confederacy - Thomas Boaz

Union in Peril: The Crisis over British Intervention in the Civil War - Howard Jones


Are any of these titles worth the read? Which is the best? Is there a better one I missed?

One more

The Alabama, British Neutrality, and the American Civil War - Frank Merli

 

[LedgerSko]

Has anyone read any of these?
