United States Secretary of War in the context of "United States Department of War"

The United States Department of the Navy (DON) is one of the three military departments within the United States Department of Defense. It was established by an Act of Congress on 30 April 1798, at the urging of Secretary of War James McHenry, to provide a government organizational structure to the United States Navy (USN). Since 1834, the department has exercised jurisdiction over the United States Marine Corps (USMC), and during wartime the United States Coast Guard (USCG). These branches remain at all times independent and coequal service branches within the DON. It is led by the secretary of the Navy (SECNAV), a statutory civilian officer.

The Department of the Navy was an executive department, whose secretary served on the president's cabinet, until 1949, when amendments to the National Security Act of 1947 established the Department of Defense as a unified department for all military services; the DON, along with the Department of the Army and Department of the Air Force, became a component of the DoD, subject to the authority, direction and control of the secretary of defense.

The secretary of the Army (SA or SECARMY) is a senior civilian official within the United States Department of Defense, with statutory responsibility for all matters relating to the United States Army: manpower, personnel, reserve affairs, installations, environmental issues, weapons systems and equipment acquisition, communications and financial management.

The secretary of the Army is nominated by the president of the United States and confirmed by the United States Senate. The secretary is a non-Cabinet-level official, subordinate to the secretary of defense. This position was created on September 18, 1947, replacing the secretary of war, when the Department of War was split into the Department of the Army and Department of the Air Force.

James McHenry (November 16, 1753 – May 3, 1816) was an Irish American military surgeon, statesman, and a Founding Father of the United States. McHenry was a signer of the United States Constitution from Maryland, initiated the recommendation for Congress to form the Navy, and was the eponym of Fort McHenry. He represented Maryland in the Continental Congress. He was a delegate to the Maryland State Convention of 1788, to vote whether Maryland should ratify the proposed Constitution of the United States. He served as United States Secretary of War from 1796 to 1800, bridging the administrations of George Washington and John Adams. At the time of his death, McHenry owned 10 slaves, most of whom either worked as household servants or maintained his estate.

John Bell (February 18, 1796 – September 10, 1869) was an American politician, attorney, and planter who was a candidate for President of the United States in the election of 1860.

One of Tennessee's most prominent antebellum politicians, Bell served in the House of Representatives from 1827 to 1841, and in the Senate from 1847 to 1859. He was Speaker of the House for the 23rd Congress (1834–1835), and briefly served as Secretary of War during the administration of William Henry Harrison (1841). In 1860, he ran for president as the candidate of the Constitutional Union Party, a third party which took a neutral stance on the issue of slavery. He won the electoral votes of three states by a slim margin.

Jefferson F. Davis (June 3, 1808 – December 6, 1889) was an American politician who served as the only president of the Confederate States from 1861 to 1865. He represented Mississippi in the United States Senate and the House of Representatives as a member of the Democratic Party before the American Civil War. He was the United States Secretary of War from 1853 to 1857.

Davis, the youngest of ten children, was born in Fairview, Kentucky, but spent most of his childhood in Wilkinson County, Mississippi. His eldest brother Joseph Emory Davis secured the younger Davis's appointment to the United States Military Academy. Upon graduating, he served six years as a lieutenant in the United States Army. After leaving the army in 1835, Davis married Sarah Knox Taylor, daughter of future president Zachary Taylor. Sarah died from malaria three months after the wedding. Davis became a cotton planter, building Brierfield Plantation in Mississippi on his brother Joseph's land and eventually owning as many as 113 slaves.

Commanding General of the United States Army was the title given to the service chief and highest-ranking officer of the United States Army (and its predecessor the Continental Army), prior to the establishment of the chief of staff of the United States Army in 1903. During the American Revolutionary War (1775–1783), the title was Commander-in-Chief of the Continental Army. Between 1783 and 1821, there was no true overall commander for the army. Historians use the term Senior Officer of the United States Army to refer to the individual that held the highest rank by virtue of his date of commission, though the authority they exerted depended on the will of the secretary of war. In 1821, Secretary John C. Calhoun appointed Jacob Brown as the Commanding General of the United States Army, thus establishing the office of Commanding General. The office was often referred to by various other titles, such as "Major General Commanding the Army" or "General-in-Chief".

From 1789 until its abolition in 1903, the position of commanding general was legally subordinate to the United States secretary of war; (senior member of the President's Cabinet), but was replaced by the creation of the statutory chief of staff of the Army by action of the United States Congress in 1903, under the 26th president Theodore Roosevelt (1901–1909).

The Confederate States Army (CSA), also called the Confederate army or the Southern army, was the military land force of the Confederate States of America (commonly referred to as the Confederacy) during the American Civil War (1861–1865), fighting against the United States forces to support the rebellion of the Southern states and uphold and expand the institution of slavery. On February 28, 1861, the Provisional Confederate Congress established a provisional volunteer army and gave control over military operations and authority for mustering state forces and volunteers to the newly chosen Confederate States president, Jefferson Davis (1808–1889). Davis was a graduate of the United States Military Academy, on the Hudson River at West Point, New York, and colonel of a volunteer regiment during the Mexican–American War (1846–1848). He had also been a United States senator from Mississippi and served as U.S. Secretary of War under 14th president Franklin Pierce. On March 1, 1861, on behalf of the new Confederate States government, Davis assumed control of the military situation at Charleston Harbor in Charleston, South Carolina, where South Carolina state militia had besieged the longtime Federal Fort Sumter in Charleston harbor, held by a small U.S. Army garrison under the command of Major Robert Anderson (1805–1871). By March 1861, the Provisional Congress of the Confederate States meeting in the temporary capital of Montgomery, Alabama, expanded the provisional military forces and established a more permanent regular Confederate States Army.

An accurate count of the total number of individuals who served in the Military forces of the Confederate States (Army, Navy and Marine Corps) is not possible due to incomplete and destroyed/burned Confederate records; and archives. Estimates of the number of Confederate soldiers, sailors and marines are between 750,000 and over 1,000,000 troops. This does not include an unknown number of black slaves who were pressed into performing various tasks for the army, such as the construction of fortifications and defenses or driving wagons. Since these figures include estimates of the total number of soldiers who served at any time during the war, they do not represent the size of the army at any given date. These numbers also do not include sailors/marines who served in the Confederate States Navy.

The flag of Washington, D.C., consists of three red stars above two red bars on a white background. It is an armorial banner based on the coat of arms granted to Lawrence Washington (George Washington's 3rd great-grandfather) of Sulgrave Manor Northamptonshire, England, in 1592. This coat of arms was used privately by the president in his home at Mount Vernon. In heraldry, the stars are called mullets and the coat of arms is blazoned as argent two bars gules, in chief three mullets of the second.

In 1938, the District Flag Commission was created by an Act of Congress "to procure a design for a distinctive flag for the District of Columbia". The District Flag Commission was composed of three non-elected federally-appointed members: the president of the Board of Commissioners, the secretary of war and the secretary of the Navy. The flag was selected by the commission with the help of the Commission of Fine Arts. Since no local group was involved in the selection process, Washingtonians saw the flag as a symbol of their lack of representation. More recently, it has been embraced by most DC residents and businesses, as well as the DC Statehood Movement as a symbol of their local identity in the 21st century.
