While Nicholson was aboard State of Georgia, the ship blockaded Wilmington, North Carolina, and fought engagements with Confederate fortifications guarding the city. After 30 days, Nicholson left the ship and returned to school. on 30 September 1869, Nicholson was appointed from the District of Columbia as a midshipman and entered the United States Naval Academy in Annapolis, Maryland. He graduated on 31 May 1873 with the rank of midshipman. Nicholsons first assignment was to the signals office in 1873. Promoted to ensign on 16 July 1874, he served aboard the sidewheelsteamfrigate in the North Atlantic Squadron from 1875 to 1877. He then had ordnance duty at the Washington Navy Yard in Washington, D.C., from 1877 to 1878. From 1878 to 1882, Nicholson was aboard the sloop-of-war, then serving as a training ship, and was promoted to master on 22 January 1880. He then performed duty at the United States Hydrographic Office from 1882 to 1885, being promoted while there to lieutenant, junior grade, on 3 March 1883. He returned to sea aboard the new steam sloop-of-war in the Pacific Squadron from 1885 to 1888, and was promoted to lieutenant on 17 January 1886. After leaving Mohican, he reported to the Washington Navy Yard for another tour of ordnance duty in 1888. Nicholson was assigned to the new monitor in February 1893, and to the steamer in January 1895. He returned to the Washington Navy Yard for a third tour there in December 1895. In December 1897, Nicholson reported for duty aboard the battleship, and he served as her chief navigation officer during her spectacular voyage from the United States West Coast around Cape Horn to Cuba at the outset of the Spanish–American War in 1898. On 1 October 1898, he was assigned to the new torpedo boat, then fitting out. Promoted to lieutenant commander on 3 March 1899, he became the first commanding officer of the new torpedo boat on 1 April 1899, then took command of Farragut when she was commissioned on 5 June 1899. He remained in command of Farragut until 1901. Nicholson next served in the Bureau of Navigation and was promoted to commander on 17 September 1902. In 1903 he was assigned to the new protected cruiser, then under construction at Union Iron Works in Mare Island, California, and became her first commanding officer when she was commissioned on 30 January 1904, remaining aboard her until December 1905. He began another tour of duty in the Bureau of Navigation on 22 June 1906, remaining there into 1907. He was promoted to captain on 1 July 1907. Nicholson took command of the battleship in 1907 and commanded her during Nebraskas participation in the 1907–1909 round-the-world cruise of the U.S. Navys Great White Fleet, which she joined in May 1908. After the conclusion of the voyage in 1909, President William Howard Taft appointed him on 1 December 1909 for a four-year tour as Chief of the Bureau of Navigation in Washington, D.C. Nicholson was promoted to rear admiral on 19 May 1911. In mid-1911, he was chosen to end his tour at the Bureau of Navigation early and succeed Rear Admiral Joseph B. Murdock as commander-in-chief of the U.S. Asiatic Fleet as of November 1911, but United States Secretary of State Philander C. Knox requested that Murdock be kept on as fleet commander to allow continuity during unrest in China related to the Xinhai Revolution of that year. Meanwhile, United States Secretary of the NavyGeorge von Lengerke Meyer had already selected Nicholsons successor as Chief of the Bureau of Navigation. President Taft explained the situation to Nicholson, who was dispatched to the Asiatic Fleet to command its Yangtze Patrol. In February 1912, with the Chinese crisis having abated, it was again proposed that Nicholson succeed Murdock, but Knox again asked that Murdock stay on as fleet commander-in-chief. On 20 July 1912, Nicholson finally received orders to take command of the fleet, and he relieved Murdock on 24 July 1912. Relinquishing command of the Asiatic Fleet on 3 May 1914, Nicholson became a member of the General Board of the United States Navy until he retired from the Navy upon reaching the statutory retirement age of 62 on 15 December 1914. At the time, he was the last U.S. Navy officer on active duty to have seen service in the American Civil War. When the United States entered World War I in April 1917, Nicholson was recalled to active duty. He headed a naval mission to Chile and served as the first American naval attaché to Ecuador and Peru from 7 November 1917 to 25 November 1919 before returning to retirement.
