Question: The Calhoun Depot  was part of an American Civil War military raid that occurred on what date?
Context: The Great Locomotive Chase or Andrews' Raid was a military raid that occurred on April 12, 1862, in northern Georgia during the American Civil War.  Volunteers from the Union Army, led by civilian scout James J. Andrews, commandeered a train and took it northward toward Chattanooga, Tennessee, doing as much damage as possible to the vital Western and Atlantic Railroad (W&A) line from Atlanta to Chattanooga as they went.  They were pursued by Confederate forces at first on foot, and later on a succession of locomotives for 87 miles. The Enrollment Act, 12 Stat.  731 , enacted March 3, 1863, also known as the Civil War Military Draft Act, was a legislation passed by the United States Congress during the American Civil War to provide fresh manpower for the Union Army.  A form of conscription, the controversial act required the enrollment of every male citizen and those immigrants who had filed for citizenship between ages twenty and forty-five.  Federal agents established a quota of new troops due from each congressional district.  In some cities, particularly New York City, enforcement of the act sparked civil unrest as the war dragged on, leading to the New York City draft riots on July 13–16.  It replaced the previous Militia Act of 1862. Southern Terminal Redoubt is a historic archaeological site located at Newport News, Virginia.  It is a uniquely intact component that represents the southern end of General John B. Magruder's defensive Warwick Line.  It is a relatively small defensive earthwork that constitutes one of the few surviving and undisturbed remnants of the 1862 Peninsula Campaign in Virginia.  It is representative of a major military feat significant to the outcome of the American Civil War and exemplifies diverse types of defensive adaptation.  An archaeological investigation of this site could yield new insights into Civil War military architecture. The Battle of Gloucester Point, Virginia was an inconclusive exchange of cannon fire between a shore battery on the York River which was manned by Virginia (soon to be Confederate) forces and the Union gunboat USS "Yankee".  The action occurred on May 7, 1861, three weeks after the start of the American Civil War (Civil War) at Fort Sumter in the harbor at Charleston, South Carolina on April 14, 1861.  The Gloucester Point engagement is notable as the earliest exchange of gunfire between the Union Navy and organized Rebel (Confederate) forces after the U.S. Army surrendered Fort Sumter to the Confederates and as the earliest reported Civil War military engagement in Virginia.  Like other early engagements between Union gunboats and Confederate shore batteries, the battle at Gloucester Point was part of the Union Navy effort to blockade the Southern States in general and the Chesapeake Bay in particular.  The engagement also was part of the effort by Confederate forces to deny the use of rivers in Virginia to Union military and commercial traffic. The Calhoun Depot was a railway station of the Western & Atlantic Railroad that was built by the State of Georgia during 1852-53 in Calhoun, Georgia.  Unusual for railroads, the Western & Atlantic Railroad was owned and operated by a U.S. state.  Calhoun is on its route built from Atlanta, Georgia to Chattanooga, Tennessee.  Like other brick or stone depots on the line, the Calhoun Depot was involved in but survived the American Civil War.  It was part of the Great Locomotive Chase. The National Civil War Naval Museum at Port Columbus, located in Columbus, Georgia, United States, is a 40000 sqft facility that features two original American Civil War military naval vessels, uniforms, equipment and weapons used by the United States (Union) Navy from the North and the Confederate States Navy (Southern /Rebel) forces.  It is the only museum in the nation that tells the story of the two navies during the Civil War. Duffields Depot is a former Baltimore and Ohio Railroad station on the National Register of Historic Places, located in the village of Duffields, West Virginia, near Shenandoah Junction.  Built in 1839, the depot is the second oldest surviving B&O depot.  Only the Ellicott City Station in Ellicott City, Maryland is older.  The depot and its enviroins were a significant focus of activity during the American Civil War, culminating in the "Greenback Raid" of 1864. The Old Gainesville Depot (also known as the Seaboard Air Line Depot or Baird Warehouse) is a historic site at 203 Southeast Depot Avenue in Gainesville, Florida.  It was added to the U.S. National Register of Historic Places on November 22, 1996.  Part of the Depot was built around 1860 to serve the Florida Railroad, which reached Gainesville from Fernandina in 1859.  It is one of only three surviving railroad depots in the state built prior to the start of the American Civil War.  The depot was situated with tracks on both sides.  Between 1892 and 1897 the depot was remodeled to provide two passenger waiting rooms, one for whites and one for Blacks.  A new passenger depot with segregated waiting rooms was built in 1910, and the old depot was moved and attached as a freight house to the passenger depot.  Depot operations were moved to a new building where East University Avenue crossed the rail line in January, 1948.  After the railroad opened the new depot, the old depot building was used by Baird Hardware, Gator Ice and Voyles Appliance store.  The City of Gainesville acquired the depot building in 1999. The Battle of Pig Point, Virginia was an engagement between the Union gunboat USRC "Harriet Lane" and a shore battery and rifle company of the Confederate Army on June 5, 1861 in the third month of the American Civil War.  Pig Point is located in Portsmouth, Virginia at the mouth of the Nansemond River near Hampton Roads, Virginia.  This location is about 5 mi from Newport News, Virginia.  The engagement occurred before any significant battles, other than the opening Battle of Fort Sumter, had taken place and received some notoriety at the time.  The action was essentially inconclusive, but the Confederates repulsed the Union gunboat's attack, and the defenders' gunfire wounded five of its crew.  Like other early engagements between Union gunboats and Confederate shore batteries, the battle at Pig Point was an early Civil War military action in connection with the blockade by the Union Navy of the Southern States in general and Chesapeake Bay in particular.  Correspondingly, it was part of the effort by Confederate forces to deny the use of rivers in Virginia to Union military and commercial traffic. The Burning Raid was a Union military raid conducted in the Loudoun Valley of Loudoun and Fauquier counties in Virginia in November and December 1864 during the American Civil War.  It was aimed at destroying the forage on which Confederate partisans operating in the area, specifically Mosby's Rangers, subsisted as well as at breaking the will of the citizens of the area for supporting the partisans.
