North Carolina Seceded
Chesapeake Bay Blockade
CSA. The Confederate Provisional Congress voted to adjourn and to move the Capital of the Confederacy from Montgomery, Alabama, to Richmond, Virginia. Congress resolved to resume its session on 20 July 1861.
CSA. The Confederate Marine Corps was expanded to the size of a regiment following an act of the Provisional Congress. The force was authorized to consist of 1,000 men.
USA. The US government announced the seizure of control of telegraph offices, equipment, and archived dispatches throughout the United States.
District of Columbia. Commander James Harmon Ward USN arrived at the Washington Navy Yard aboard his flagship, USS Thomas Freeborn, to activate the “Flying Flotilla” or Potomac Flotilla. The designation of “Flying Flotilla” was dropped when Ward’s force arrived in the theatre of operations and the force was referred to by a variety of names, such as the Potomac River Flotilla or Potomac Blockade, or Flotilla in the Chesapeake. In early August 1861, the commander and the Navy Department began to consistently refer to the command as the Potomac Flotilla.
District of Columbia. The garrison of Fort McHenry was reinforced. It was never seriously threatened by local secessionists and became the headquarters of the Department of the East in July 1861.
Florida. USS Crusader, Lieutenant Thomas A Craven USN, landed a party and occupied Neptune near Fort Zachary Taylor.
Kentucky. Kentucky Governor Beriah Magoffin issued a proclamation of neutrality.
Maryland. Union forces in Baltimore seized a store of 1,600 muskets and 4,000 pikes that were at risk of capture by secessionist agitators..
Maryland. State Major-General George Cadwalader took command of the Union camp at Federal Hill near Baltimore.
North Carolina. The North Carolina Convention met, ratified the Confederate Constitution, and passed an Ordinance of Secession. North Carolina eventually contributed 125,000 soldiers to the Confederacy, despite some sections in the west of the state having a strong pro-Union and anti-slavery sentiment. The state came to lead the South in blockade-running and provided a significant proportion of supplies to the Confederate armies. The secession of North Carolina left only four slave-holding states officially outside the Confederacy: the so-called Border States of Missouri, Delaware, Maryland, and Kentucky. North Carolina was the eleventh state to secede.
Pennsylvania. The prize ship General Parkhill was brought into Philadelphia by a prize crew from the USS Niagara.
Texas. Fort Duncan was abandoned by the US Army. Fort Duncan was established to protect the first American settlement on the Rio Grande near the present-day town of Eagle Pass. It was one of a line of seven army posts built after the Mexican War to protect West Texas, which included Fort Worth, Fort Graham, Fort Gates, Fort Croghan, Fort Martin Scott, Fort Lincoln, and Fort Duncan. Fort Duncan was established on 27 March 1849 by Captain Sidney Burbank and companies A, B, and F of the 1st US Infantry. On 14 November 1849, the post was named after Colonel James Duncan. Fort Duncan provided protection from border outlaws and became a base for scouting Native Americans. The fort was abandoned in May 1859 and then reoccupied in March 1860 during the Cortina Troubles. When US Brigadier-General David Emanuel Twiggs ordered the fort to be evacuated on 21 February 1861, Major William Henry French successfully evacuated three companies of artillery from Fort Duncan and two from Fort Brown to Fort Jefferson and Fort Zachary Taylor in Florida. The Confederates garrisoned the fort with volunteers and Texas Rangers, renaming it Rio Grande Station. It became an important port for the export of cotton into Mexico. US Army troops did not reoccupy Fort Duncan until 23 March 1868.
