This pamphlet describes the critical role of Army officers who defied the odds and saw this immense project through to completion. They included Col. William C. Gorgas, who supervised the medical effort that saved countless lives and made it possible for the labor force to do its job; Col. George W. Goethals, who oversaw the final design of the canal and its construction and, equally important, motivated his workers to complete the Herculean task ahead of schedule; and many other officers who headed up the project's subordinate construction commands and rebuilt the Panama railroad, a key component of the venture. In just seven years, these soldiers, thousands of fellow Americans, and tens of thousands of workers from around the world turned the dream of an isthmian canal into reality. Their success immediately ranked among the greatest peacetime feats of the Army and the nation, and it remains so to this day. Jon Hoffman retired as a colonel from the Marine Corps Reserve in 2008 after thirty years, including seventeen years of active duty. His active-duty service included command of two infantry companies, completion of three amphibious deployments, three years as a history instructor at the U.S. Naval Academy and two years as the deputy director of the Marine Corps History and Museums Division. In his civilian career, he has been the Deputy Chief Historian for the Secretary of Defense Historical Office, and is presently the Chief Historian for the U.S. Army Center of Military History. The Panama Canal is an artificial 51-mile waterway in Panama that connects the Caribbean Sea in the Atlantic Ocean with the Pacific Ocean. It cuts across the narrowest point of the Isthmus of Panama and is a conduit for maritime trade between the Atlantic Ocean and the Pacific Ocean. Locks at each end lift ships up to Gatun Lake, an artificial fresh water lake 85 feet above sea level, created by damming the Chagres River and Lake Alajuela to reduce the amount of excavation work required for the canal. Locks then lower the ships at the other end. The original locks are 110 feet wide and allow the passage of Panamax ships. A third, wider lane of locks was constructed between September 2007 and May 2016. The expanded waterway began commercial operation on 26 June 2016. The new locks allow for the transit of larger, Neopanamax ships. An average of 52 million US gallons of fresh water is used in a single passing of a ship. The canal is threatened by low water levels during droughts. The Panama Canal shortcut greatly reduces the time for ships to travel between the Atlantic and Pacific oceans, enabling them to avoid the lengthy, hazardous route around the southernmost tip of South America via the Drake Passage, the Strait of Magellan or the Beagle Channel. Its construction was one of the largest and most difficult engineering projects ever undertaken. Since its inauguration on 15 August 1914, the canal has succeeded in shortening maritime communication in time and distance, invigorating maritime and economic transportation by providing a short and relatively inexpensive transit route between the two oceans, decisively influencing global trade patterns, boosting economic growth in developed and developing countries, as well as providing the basic impetus for economic expansion in many remote regions of the world. Colombia, France, and later the United States controlled the territory surrounding the canal during construction. France began work on the canal in 1881, but stopped in 1889 because of a lack of investors' confidence due to engineering problems and a high worker mortality rate. The US took over the project in 1904 and opened the canal in 1914. The US continued to control the canal and the surrounding Panama Canal Zone until the Torrijos-Carter Treaties provided for its handover to Panama in 1977. After a period of joint American-Panamanian control. …
