Question: The CSS Bombshell was a steamer on the second largest canal, which was completed in what year?

Charles Carroll Simms (1824–1884) a native of Virginia, became a United States Navy midshipman in 1839.  He served in the U.S. Navy for more than two decades, achieving the rank of Lieutenant in 1854.  He was dismissed from the service in April 1861, after his state left the United States, and briefly was an officer in Virginia's Navy.  Commissioned as a First Lieutenant in the Confederate States Navy in June 1861, during that year he commanded the steamer CSS "George Page" and was assigned to the steamer CSS "Rappahannock".  Also commanded CSS Appomattox in coastal North Carolina until it was scuttled in February 1862.  As an officer of the ironclad CSS "Virginia", he took part in her March–May 1862 actions in the vicinity of Hampton Roads.  Subsequently, he served in the gunboats CSS "Nansemond" on the James River, and CSS "Selma" in Mobile Bay.  During the American Civil War's final year, while assigned to the Mobile Squadron, he commanded the ironclads CSS "Baltic" and CSS "Nashville".  First Lieutenant Simms surrendered to Federal forces in early May 1865 and was paroled soon afterwards. <SEP>  "Bombshell" was sunk by the Confederate batteries in Albemarle Sound, North Carolina on April 18, 1864. CSS Bombshell — believed to have been an Erie Canal steamer — was a U.S. Army transport.  She was raised by the Confederate forces and taken into the Confederate States Navy under the command of Lieutenant Albert Gallatin Hudgins, CSN.  "Bombshell" was captured at the Battle of Albemarle Sound by USS "Mattabesett" and USS "Sassacus" on May 5, 1864 and sent to New York City. <SEP> The Erie Canal is a canal in New York that is part of the east–west, cross-state route of the New York State Canal System (formerly known as the New York State Barge Canal).  Originally, it ran 363 mi from Albany, on the Hudson River, to Buffalo, at Lake Erie.  When completed in 1825, it was the second longest canal in the world (after the Grand Canal in China) and greatly affected the development and economy of New York, New York City, and the United States.  It was built to create a navigable water route from New York City and the Atlantic Ocean to the Great Lakes. <SEP> The Indiana Mammoth Internal Improvement Act was a law passed by the Indiana General Assembly and signed by Whig Governor Noah Noble in 1836 that greatly expanded the state's program of internal improvements.  It added $10 million to spending and funded several projects, including turnpikes, canals, and later, railroads.  The following year the state economy was adversely affected by the Panic of 1837 and the overall project ended in a near total disaster for the state, which narrowly avoided total bankruptcy from the debt.  By 1841, the government could no longer make even the interest payment, and all the projects, except the largest canal, were handed over to the state's London creditors in exchange for a 50% reduction in debt.  Again in 1846, the last project was handed over for another 50% reduction in the debt.  Of the eight projects in the measure, none were completed by the state and only two were finished by the creditors who took them over.
