Halberd forms of the voulge in design and usage. The halberd was usually 1.5 to 1.8 metres (5 to 6 feet) long. The word has also been used to describe a weapon of the Early Bronze Age in Western Europe. This consisted of a blade mounted on a pole at a right angle. A very similar weapon, the dagger-axe, from Bronze Age China, has also been called "halberd" in English. The halberd was inexpensive to produce and very versatile in battle. As the halberd was eventually refined, its point was more fully developed to allow it to better deal with spears
Operation Halberd Force H was attacked by three submarines; and "Adua" was sunk by "Gurkha" and "Legion". Another "Ark Royal" Fulmar fell to friendly fire from "Prince of Wales", raising British aircraft losses to three Fulmars from friendly fire and one Swordfish from enemy action. Italian aircraft losses were 21 including seven bombers and one fighter from enemy action, one fighter from friendly fire, and ten fighters from fuel exhaustion. Admiral Somerville was knighted in recognition of his successful command of Force H during Operation Halberd. It was the second time Somerville had received that honour; and occasioned this memorable congratulatory message
