Campaign clasp

A medal bar or medal clasp is a thin metal bar attached to the ribbon of a military decoration, civil decoration, or other medal. It is most commonly used to indicate the campaign or operation the recipient received the award for, and multiple bars on the same medal are used to indicate that the recipient has met the criteria for receiving the medal in multiple theatres.

When used in conjunction with decorations for exceptional service, such as gallantry medals, the term "and bar" means that the award has been bestowed multiple times. In the example, "Group Captain Leonard Cheshire, VC, OM, DSO and Two Bars, DFC", "DSO and two bars" means that the Distinguished Service Order was awarded on three separate occasions. A British convention is to indicate bars by the use of asterisks; thus, DSO** would denote a DSO and two bars.

Bars are also used on long service medals to indicate the length of service rendered.

The two terms are used because terms "bar" and "clasp" both refer to two parts of the medal; the indicator discussed in this article, and the part of the medal connected to the ribbon.

Prior to the early 19th century, medals and decorations were only awarded to ranking officers; occasions existed where medals were presented to soldiers (other ranks or enlisted men) or seamen (naval ratings), but these were often private efforts. One exception was the Army Gold Medal issued to higher ranking participants in the Peninsular War. A medal was given for service, with a clasp for each battle fought. After four clasps were earned the medal was turned in for a cross with the battle names on the arms, and additional clasps were then added. The maximum was achieved by the Duke of Wellington, with a cross and nine clasps.
