In an excerpt from his book The Roosevelt Family of Sagamore Hill, Hermann Hagedorn examines Theodore Roosevelt’s exercise of personal diplomacy with the representatives of Russia and Japan in his effort to mediate an end to the Russo-Japanese War. Hagedorn details the delicate diplomacy undertaken by Roosevelt at Sagamore Hill and onboard the presidential yacht Mayflower in August 1905 which helped to secure a final peace treaty in Portsmouth, New Hampshire. Hagedorn also describes Roosevelt’s descent in the U.S. Navy’s submarine, the Plunger.
A photograph, a political cartoon, and an illustration depict Roosevelt’s interaction with the envoys from Russia and Japan.
