General Sir Samuel James Browne, then a captain in command of the 2nd Punjab, attacked a 9-pounder cannon that was holding off his advance. His left arm was severed by a sword. He succeeded in preventing the cannon from being reloaded and, in doing so, won the battle.
The citation for the Victoria Cross awarded for Browne's actions reads in part: "in an engagement with the Rebel Forces under Khan Allie Khan, on the 31st of August, 1858, whilst advancing upon the Enemy's position, at day break, pushed on with one orderly Sowar (horse soldier) upon a nine-pounder gun that was commanding one of the approaches to the enemy's position, and attacked the gunners, thereby preventing them from re-loading, and firing upon the Infantry, who were advancing to the attack. In doing this, a personal conflict ensued, in which Captain, now Lieutenant-Colonel, Samuel James Browne, Commandant of the 2nd Punjab Cavalry, received a severe sword-cut wound on the left knee, and shortly afterwards another sword-cut wound, which severed the left arm at the shoulder, not, however, before Lieutenant-Colonel Browne had succeeded in cutting down one of his assailants. The gun was prevented from being re-loaded, and was eventually captured by the Infantry, and the gunner slain."
Sam Browne had trouble carrying his sword after his injury and designed the hard leather belt with the shoulder strap to keep the sword from moving around so he could access it with his remaining right hand. He stayed in the British Army and invented the belt system now carrying his name. Later, when British Officers began carrying the heavy .455 Webley Mk IV pistol, the strap remained to mitigate the gun's weight. So, the duty belt you probably wear was named after one tough dude and a pretty resourceful one, too.
Traditions
Traditions are a wonderful thing for police departments. They give us perspective on where we came from, where our priorities should be set, what our role in society may be, and where we should be going. While the Sam Browne system is a part of our traditions, the updated versions are more practical in modern policing.
