During the later Roman Empire, the principal military developments were attempts to create an effective cavalry force as well as the continued development of highly specialised types of troops. The creation of heavily armoured cataphract-type soldiers as cavalry was an important feature of the 5th-century Roman military. The various invading tribes had differing emphasis on types of soldiersranging from the primarily infantry Anglo-Saxon invaders of Britain to the Vandals and Visigoths, who had a high proportion of cavalry in their armies. During the early invasion period, the stirrup had not been introduced into warfare, which limited the usefulness of cavalry as shock troops because it was not possible to put the full force of the horse and rider behind blows struck by the rider. The greatest change in military affairs during the invasion period was the adoption of the Hunnic composite bow in place of the earlier, and weaker, Scythian composite bow. Another development was the increasing use of longswords and the progressive replacement of scale armour by mail armour and lamellar armour.

What Scythian weapon was used during this era?
Answer: composite bow

For over a century, New Haven citizens had fought in the colonial militia alongside regular British forces, as in the French and Indian War. As the American Revolution approached, General David Wooster and other influential residents hoped that the conflict with the government in Britain could be resolved short of rebellion. On 23 April 1775, which is still celebrated in New Haven as Powder House Day, the Second Company, Governor's Foot Guard, of New Haven entered the struggle against the governing British parliament. Under Captain Benedict Arnold, they broke into the powder house to arm themselves and began a three-day march to Cambridge, Massachusetts. Other New Haven militia members were on hand to escort George Washington from his overnight stay in New Haven on his way to Cambridge. Contemporary reports, from both sides, remark on the New Haven volunteers' professional military bearing, including uniforms.

Who was the captain of New Haven's Second Company, Governor's Foot Guard?
Answer: Benedict Arnold

During the 1760s and early 1770s, relations between the Thirteen Colonies and Britain became increasingly strained, primarily because of resentment of the British Parliament's attempts to govern and tax American colonists without their consent. This was summarised at the time by the slogan "No taxation without representation", a perceived violation of the guaranteed Rights of Englishmen. The American Revolution began with rejection of Parliamentary authority and moves towards self-government. In response Britain sent troops to reimpose direct rule, leading to the outbreak of war in 1775. The following year, in 1776, the United States declared independence. The entry of France to the war in 1778 tipped the military balance in the Americans' favour and after a decisive defeat at Yorktown in 1781, Britain began negotiating peace terms. American independence was acknowledged at the Peace of Paris in 1783.

When did Britain recognize American independence?
Answer:
1783
