6. TELEGRAPH-- 50,000 miles of telegraph wire had been strung by 1860. Another 15,000 miles were added during the war. Lincoln used it for real-time information. By October 1861, the coast-to-coast telegraph had eliminated the Pony Express. During the war, several patents improved distance and power of the original Morse telegraph.
7. IRON GUNSHIPS-- The Confederate Navy couldn't match the U.S. Navy in numbers so needed a super weapon which they got with the ironclad CSS Virginia. The USS Monitor was built in 90-days and had 40 patentable inventions by John Ericsson.
