Frederick Crocker (1821-1911) was an American naval commander and US consul.
Crocker was born in 1821 in Brockton, Massachusetts, the youngest son of a well-to-do farmer and manufacturer. His father sent him to work in nearby New Bedford, Massachusetts, then a booming whaling town, when he was 16 years old. Attracted by the adventure of a life at sea, he left the family business to join the most important whaling company in New Bedford, at 17. Although the youngest on board, he became the leader of a harpooning party. In his free time he studied books that taught him his trade. At 24, he was captain of a whaling vessel. He hunted whales in the most remote waters of the globe during 13 years. Starting in 1851, he joined the American merchant marine serving as captain of clipper ships, carrying cargo and passengers to the Far East and San Francisco.
At 34, he married the daughter of a wealthy Vineyard whaler in Liverpool, England. With the arrival of two sons and a daughter in 1856-1860, he remained closer to the family home in Edgartown, Martha's Vineyard. By 1860, he had become captain and part owner of a passenger and cargo steamer, the R.R. Cuyler, which sailed along the East Coast of North America between New York City and Savannah, Georgia and was reputed for its speed.
The Civil War radically changed his life. At age 40, he volunteered for service in the first weeks of the conflict. As a Union Navy gunboat skipper, he displayed great courage and ability in many successful naval engagements. He served on the Mississippi and along the US coast of the Gulf of Mexico, and distinguished himself in battles and incidents at Apalachicola Bay, Sabine Pass, Calcasieu River, Camp Bisland and Butte-à-la-Rose, among others.
His most dramatic exploit was his six-day, 80-mile dash through enemy-held Louisiana in October 1862. He and his party captured the senior Confederate officer in the Calcasieu area, gained possession of eight enemy vessels (one of them single-handedly), defeated rebel infantry and burned their encampment, fought off a cavalry attack, destroyed a bridge and stores, returning safely, without a single casualty. He also picked up refugees and took hostages, reportedly destroying a considerable amount of private property and capturing a large number of cotton bales. In recognition of his initiative, Rear-Admiral David G. Farragut recommended him enthusiastically for promotion.
