The series premiered on September 17, 1972, and ended on February 28, 1983, with the finale becoming the most-watched television episode in U.S. television history at the time.
“Goodbye, Farewell and Amen” was the final episode of M*A*S*H. Special television sets were placed in PX parking lots, auditoriums, and dayrooms of the US Army in Korea so that military personnel could watch that episode; this in spite of 14 hours’ time zone difference with the east coast of the US. The episode aired on February 28, 1983, and was 2½ hours long.
H. L. Hunley was a submarine of the Confederate States of America that fought in the American Civil War. Hunley demonstrated the advantages and dangers of undersea warfare. She was the first combat submarine to sink a warship (USS Housatonic), although Hunley was not completely submerged and, following her attack, was lost along with her crew before she could return to base. Twenty-one crewmen died in the three sinkings of Hunley during her short career. She was named for her inventor, Horace Lawson Hunley, shortly after she was taken into government service under the control of the Confederate States Army at Charleston, South Carolina.
On 17 February 1864, Hunley attacked and sank the 1,240-ton United States Navy screw sloop-of-war Housatonic, which had been on Union blockade-duty in Charleston’s outer harbor. Hunley did not survive the attack and sank, taking all eight members of her third crew with her, and was lost.
Finally located in 1995, Hunley was raised in 2000 and is on display in North Charleston, South Carolina, at the Warren Lasch Conservation Center on the Cooper River. Examination in 2012 of recovered Hunley artifacts suggested that the submarine was as close as 20 ft (6.1 m) to her target, Housatonic, when her deployed torpedo exploded, which caused the submarine’s sinking.
