Thomas Jefferson, while serving as United States Minister to France, wrote this letter to George Washington on July 17, 1785. This brief but fascinating letter discusses the possible use of submarines in warfare. Jefferson inquires about the progress of underwater experiments conducted by David Bushnell, and asks Washington's opinion regarding whether this method is capable of success.
