The Battle of Crécy was one of the most decisive victories in the Middle Ages. Events began with King Philip VI of France declaring the English land in France forfeit. Henry, Earl of Derby made significant gains in Gascony for King Edward III but then was besieged by the French. He demanded support from the English King.
So King Edward gathered an army and landed in Normandy. It was the largest invasion force until D-Day.
Edward burnt his way to Paris. Within 2 miles of Paris Edward was confronted by superior forces and trapped on the wrong side of the Somme. His army was starved by the French scorched earth policy.
The English, only 6 miles away from the French Army forced their way across a defended tidal ford. Here they broke into an area which had not been scorched and were able to resupply. This success also restored English moral as the French defenders could not stand against the longbow men.
King Edward set up a defensive position at Crecy-en-Ponthieu, on land he owned. It offered protection from flanking attacks and an uphill struggle for the French attackers. The English dug pits to make French attacks more difficult. The English were badly outnumbered. Estimates vary but the French at least had double the number of troops. The English had about 15,000 troops, the French between 30,000 and 100,000.
The first attack came from Genoese crossbowmen but the English and Welsh longbow men had the advantage of range and the Italians soon retreated. French men-at-arms attacked in some confusion, killing Genoese as they attacked but were repulsed after terrible fighting. Wave after wave of French attacks followed. None succeeding. At the end of the two day battle very few English men were killed and many thousands of French, including the flower of the nobility.
English losses were 300 or less and the French lost are sometimes estimated as 30,000, but a third of that is probably more realistic.
The battle changed opinions about British fighting ability, and showed that heavily armoured wealthy knights could not stand against trained yeoman archers armed with long bows. The archers could shoot 3 arrows a minute with a range of up to 300 yards. There may have shot half a million arrows.
But it can also be argued that the victory lulled the English into the belief that they could hold France. This led to the fruitless slaughter of the 100 years war which England ultimately lost.
On the other hand Edward III captured Calais which remained an important and strategic asset until the 16th Century.
