Decisive Arab Defeat
Al Ghafiqi attacked his enemy even though he wasn’t sure how large the Frankish force was; the trees obscured his vision. In medieval warfare, cavalry usually defeated infantry but at the Battle of Tours, Martel’s men fended off repeated attacks before the Arabs finally broke through and attempted to kill the Frankish leader. Martel’s personal guard saw the danger and closed ranks to keep their commander protected.
Although Martel’s army was probably outnumbered and contained no heavy cavalry, the men were exceptionally well trained and carried up to 75 pounds of armor into battle. Some of these men had fought with him since 717, and they were able to hold off the vicious assaults of their enemies. At this point, there is a divergence in the chronicles as to what happened next. Arab sources suggest that Frankish scouts started raiding the Muslim supply train and camp which caused the soldiers to retreat and save their plunder. Frankish sources claim that the Franks merely spread a rumor that they were attacking the supply train and this was enough to cause confusion on the battlefield.
Whatever the reason, a significant amount of Muslim cavalry left the field. The infantry misread the situation as a sign of a full retreat and began to flee. Al Ghafiqi tried to stop the retreat but only succeeded in getting himself surrounded by the enemy who executed him on the spot. Martel ordered the resumption of the phalanx formation in the belief that the Arabs would return the following day.
When they failed to appear, the Franks suspected an ambush, so Martel refused to leave his position. Eventually, Frankish soldiers launched a full-scale investigation of the Umayyad camp and discovered that the Arabs had fled during the night, carrying with them as much booty as possible. Europe had been saved, for now.
Aftermath & Analysis
The Umayyads attempted another invasion of Gaul and launched their raid through Iberia in 735. This second invasion lasted for four years and was arguably more dangerous than the first. However, internal turmoil forced the Umayyads to abandon their quest and return home. The Arabs remained in control of Septimania and Narbonne for over a quarter of a century after Tours but were unable to expand any further.
When the Caliphate embarked on a civil war at the Battle of the Zab in 750, it was only a matter of time before the Arab threat in Western Europe was eliminated. Charles focused on isolating the invaders at Narbonne and Septimania and in 759, his son, Pepin the Short, forced the surrender of Narbonne and the Umayyad dynasty was expelled from the region.
The Arab leader, Al Ghafiqi, made a crucial strategic error by not moving against Martel and by underestimating his army. By doing so, he allowed Martel to choose the battlefield and time of the fight. As the Muslim leader didn’t think the Franks would come to the aid of Aquitaine, he didn’t do a proper assessment of their strength. He also didn’t scout Frankish army movements.
It was also a mistake to waste resources fighting weaker enemies such as Odo when Martel was the real threat. They had needless casualties before Tours and were also burdened by the enormous amount of booty they carried. Martel commanded the situation masterfully and according to Edward Gibbons, had the Frankish leader lost at Tours, the Umayyad Caliphate could easily have conquered a divided Europe.
While modern historians sometimes state that the importance of Tours is overrated, there is no doubt about its impact on Western Europe. According to Henry Hallam, a Frankish defeat at Tours would have meant no Charlemagne, no Holy Roman Empire, and no Papal State establishment; how different would Europe have been then.
