The Badge of Military Merit, as it was called, fell into oblivion until 1932, when General Douglas MacArthur, then Army Chief of Staff, pressed for its revival. Officially reinstituted on February 22, 1932, the now familiar Purple Heart was at first an Army award, given to those who had been wounded in World War I or who possessed a Meritorious Service Citation Certificate. In 1943, the order was amended to include personnel of the Navy, Marine Corps, and Coast Guard. Coverage was eventually extended to include all services and "any civilian national" wounded while serving with the Armed Forces.

Although the Badge of Military Merit fell into disuse after the Revolutionary War, the idea of a decoration for individual gallantry remained through the early 1800s. In 1847, after the outbreak of the Mexican-American War, a "certificate of merit" was established for any soldier who distinguished himself in action. No medal went with the honor. After the Mexican-American War, the award was discontinued, which meant there was no military award with which to recognize the nation's fighting men.

Early in the Civil War, a medal for individual valor was proposed to General-in-Chief of the Army Winfield Scott. But Scott felt medals smacked of European affectation and killed the idea.

Shortly after this, a resolution similar in wording was introduced on behalf of the Army. Signed into law July 12, 1862, the measure provided for awarding a medal of honor "to such noncommissioned officers and privates as shall most distinguish themselves by their gallantry in action, and other soldierlike qualities, during the present insurrection." 

Almost 3,400 men and one woman have received the award for heroic actions in the nation's battles since that time.

One of the Connecticut native recipients of the nations highest award was Captain Robert Nett.  His acts of valor are detailed in this except from the citation which accompanied the award:

NETT, ROBERT B.

Rank and organization: Captain (then Lieutenant), U.S. Army, Company E, 305th Infantry, 77th Infantry Division. Place and date: Near Cognon, Leyte, Philippine Islands,14 December 1944. Entered service at: New Haven, Conn. Birth: New Haven, Conn. G.O. No.: 16, 8 February 1946. Citation: He commanded Company E in an attack against a reinforced enemy battalion which had held up the American advance for 2 days from its entrenched positions around a 3-story concrete building. With another infantry company and armored vehicles, Company E advanced against heavy machine gun and other automatic weapons fire with Lt. Nett spearheading the assault against the strongpoint. During the fierce hand-to-hand encounter which ensued, he killed 7 deeply entrenched Japanese with his rifle and bayonet and, although seriously wounded, gallantly continued to lead his men forward, refusing to relinquish his command. Again he was severely wounded, but, still unwilling to retire, pressed ahead with his troops to assure the capture of the objective. Wounded once more in the final assault, he calmly made all arrangements for the resumption of the advance, turned over his command to another officer, and then walked unaided to the rear for medical treatment. By his remarkable courage in continuing forward through sheer determination despite successive wounds, Lt. Nett provided an inspiring example for his men and was instrumental in the capture of a vital strongpoint.
