In the early afternoon, a series of explosions rocked Fort Lyon on Eagle's Hill, south of Alexandria, Virginia.  Eight tons of black powder in the main magazine exploded, along with thousands of rounds of small arms munitions and devastated the center of the camp.  The garrison, members of the Third New York Artillery, suffered more than twenty deaths and more than a dozen badly injured in the accident.  (By John Osborne) 

The Cincinnati-built steamboat, Lady Walton, built in 1858, had been operating since the start of the war in the Confederate service, carrying men and materials on the Arkansas River. She left Little Rock under her Illinois-born captain, Moses Pennington, with orders to deliver corn up the White River.  On a plan agreed between Pennington and his nine man crew, three white and six black, the Lady Walton instead headed for the Mississippi River and surrendered to the first U.S. Navy gunboat she saw, the U.S.S. Tyler.  (By John Osborne)
