On August 26, 1346, the Battle of Crécy, south of Calais in Northern France took place. Edward III's English longbows defeated Philip VI's army. Cannons were used for first time in battle by the English. From the article:
"The English army was led by Edward III; it mainly comprised English and Welsh troops along with allied Breton, Flemish, and German mercenaries. The exact size and composition of the English force is not known. Andrew Ayton suggests a figure of around 2,500 men-at-arms: nobles and knights, heavily armoured and armed men, accompanied by their retinues. The army contained around 5,000 longbowmen, 3,000 hobelars (light cavalry and mounted archers) and 3,500 spearmen.[16] Clifford Rodgers suggests 2,500 men-at-arms, 7,000 longbowmen, 3,250 hobelars and 2,300 spearmen.[17] Jonathon Sumption believes the force was somewhat smaller, based on calculations of the carrying capacity of the transport fleet that was assembled to ferry the army to the continent. Based on this, he has put his estimate at around 7,000–10,000.[18]
The power of Edward's army at Crécy lay in the massed use of the longbow: a powerful tall bow made primarily of yew. Upon Edward's accession in 1327, he inherited a kingdom beset with two zones of conflict: Aquitaine and Scotland. England had not been a dominant military force in Europe: the French dominated in Aquitaine, and Scotland had all but achieved its independence since the Battle of Bannockburn in 1314. Previously, pitched battles in the medieval era had largely been decided by the massed charge of heavily armoured mounted knights, a widely feared force in their heyday. However, battles such as Manzikert had demonstrated their vulnerability to nimble mounted archers on fast horses, while engagements such as the Golden Spurs, Stirling, and Bannockburn, heralded the rise of the infantryman in effectively countering the armoured charge. Infantry did have significant advantages over heavily armoured cavalry; they were far cheaper to train and equip by comparison, and offered greater tactical flexibility, in that they could be deployed on almost any terrain.[19]
Longbows had been effectively used before by English armies. Edward I successfully used longbowmen to break up static Scottish schiltron formations at the Battle of Falkirk in 1298; however it was not until Edward III's reign that they were accorded greater significance in English military doctrine. Edward realised the importance of inflicting severe damage upon an enemy force before melée combat began; at Halidon Hill in 1333, he used massed longbowmen and favourable terrain to inflict a significant defeat on the Scots forces to very few casualties of his own—in some ways a harbinger of his similar tactics at Crécy. To ensure he had a force of experienced and equipped archers to call upon, Edward ingrained archery into English culture. He encouraged archery practice, and the production of stocks of arrows and bows in peacetime, as well as war. In 1341, when Edward led an expedition to Brittany, he ordered the gathering of 130,000 sheaves, a total of 2.6 million arrows; an impressive feat on such short notice.[20]
A common claim for the longbow was its ability to penetrate plate armour due to its draw weight, a claim contested by contemporary accounts and modern tests. A controlled test conducted by Mike Loades at the Royal Military College of Science's ballistics test site for the programme Weapons That Made Britain – The Longbow found that arrows shot at a speed of around 52 metres per second against a plate of munition-quality steel (not specially hardened) were ineffective at a range of around 80 metres, enough to mildly bruise/wound the target at 30 metres, and lethal at a range of 20 metres.[21] Archery was described as ineffective against plate armour by contemporaries at battles such as Bergerac in 1345, Neville's Cross in 1346 and Poitiers in 1356. Later studies also found that late period plate armour such as that employed by Italian city-state mercenary companies was effective at stopping contemporary arrows.[22][23] Horses, however, were almost wholly unprotected against arrows, and arrows could penetrate the lighter armour on limbs. Clifford Rodgers, commenting on the later, similar Battle of Agincourt, argues that the psychological effect of a massive storm of arrows would have broken the fighting spirit of the target forces.
Archers were issued with around 60–72 arrows before a battle began. Most archers would not shoot at the maximum rate, around six per minute for the heaviest bows,[24] as the psychological and physical exertion of battle strained the men. As the battle wore on, the arm and shoulder muscles would tire from exertion, the fingers holding the bowstring would strain and the stress of combat would slacken the rate of fire.[25]
The English army was also equipped with five ribauldequin, an early form of cannon."
