A History of War in 100 Battles. Richard Overy

and untrustworthy Maxentius, marched across the Alps at Susa to try his luck at capturing Rome, still regarded as the centre of the empire. His army captured Turin and Milan, won a battle at Brescia, then laid siege to Verona, where it defeated Maxentius’s leading general as he tried to flee. From a small force, Constantine’s army was augmented by deserters from Maxentius’s cause. He marched south towards Rome, mustering an estimated 50,000 men.

      To oppose him, Maxentius had perhaps 100,000 men to call on, though many were less well-trained than those of his opponent, raised from levies forced on a reluctant population. He gathered stores of wheat and supplies to withstand a siege, as he had done successfully with Galerius. To hold up Constantine’s advance, he ordered the destruction of the wide stone Milvian Bridge across the Tiber, which lay on the path of his enemy’s army. But at the last moment he changed his mind and decided that his forces were large enough to secure a land victory. A new pontoon bridge was constructed, and Maxentius led his large army across it to Saxa Rubra. At the core were the famous Praetorian Guards (the elite imperial bodyguard), and on the flanks were the new heavy cavalry modelled on the Persian example. Opposed to them was a conventional force of Roman infantry supported to either side by experienced horsemen. Constantine’s forces, so it is said, were told to paint the ‘chi-rho’ sign on their shields to show that they were protected by the new Christian God. They marched into battle inspired by Constantine’s vision and the certainty of victory.

      Victory was in fact far from certain, since Maxentius had the much larger force, but Constantine, in imitation of Alexander the Great, led his seasoned cavalry in a determined charge against the horsemen on the flanks of Maxentius’s army. Little is known in detail about the battle, and what is recorded comes from a later account by the Christian bishop Eusebius, based on conversations with Constantine, and cannot be regarded as reliable. However, the outcome is known with certainty. Constantine’s cavalry smashed their opponents and drove them back to the Tiber. The infantry lines of Maxentius were exposed to flank attacks and the line caved in. Panicking soldiers fled to the pontoon bridge or tried to cross the river, while the Praetorian Guard held its ground and was cut down rank by rank where it stood. Whether the pontoon bridge collapsed or the unruly crowd surging across it pushed others into the water, the fleeing Maxentius ended up drowned in the Tiber, weighed down by his armour. His body was dredged out and decapitated, and his head displayed on a lance as Constantine marched on into the city.

      The extent to which Constantine’s army fought and won because of his vision is open to debate. His forces won notable military successes in northern Italy without the aid of divine inspiration, but with an astute and experienced commander to guide them. It is not clear how Constantine himself interpreted his vision, since he had previously claimed to see visions of pagan gods, particularly Apollo. After his capture of Rome, which left him as unchallenged ruler of the western part of the empire, he admitted to many subsequent visions of Jesus. Modern accounts suggest a possible atmospheric phenomenon which Constantine interpreted as he wished, but since he claimed to have had visions often, he may have been the victim of hallucinations caused, experts now think, by a particular form of migraine. Whatever the truth, Constantine knew how to use the vision to his advantage; in this case it must have reinforced the confidence of his men in a leader who had already proved his qualities on numerous occasions. There are times in battle when a perceptive leader can see how the supernatural might help, as Alexander had at Gaugamela.

      The Battle of the Milvian Bridge became a reference point for the establishment of Christianity in the Western Roman Empire. A year after the battle, Constantine published an edict of religious toleration at Milan and, although only a small percentage of the Roman population was yet Christian, the victory at the bridge and the support of Constantine for Christianity worked rapidly to spread the religion, with its now protected status, across the Western Empire. The legends surrounding the Milvian Bridge were what counted, not the truth of a battle that was just one of many internecine conflicts in the fading years of Roman imperial rule, won by a man who had been happily pagan only years before.

BATTLE OF HASTINGS 14 October 1066

      The most famous battle in all English history is undoubtedly the bloody day-long struggle between the Anglo-Saxon forces of the English king, Harold II, and the invading army of William, Duke of Normandy. It has been known for centuries as the Battle of Hastings, but it was fought on a narrow slope leading up to what is now the small Sussex town of Battle, halfway between Pevensey and Hastings, a short distance from the English Channel. With around 7,000 men apiece, William and Harold battled for the future history of England.

      The cause of the battle was the straightforward prospect of ruling a prosperous and fertile country. English territory was divided between areas of Viking and Anglo-Saxon settlement, and for several centuries had been the object of the ambitions of Scandinavian rulers. The throne of England was an unstable inheritance, and when King Edward, known as the Confessor, died on 5 January 1066 without an heir, there were a number of claimants to the English throne. The English earls elected Harold Godwinson, Earl of Wessex (in southwest England), who had no direct blood ties to the royal line, but was a tough and successful warrior. In the space of less than a year, he faced two separate invasions by claimants who did have royal blood, and believed that the throne belonged to them. In September 1066, the king of Norway, Harald Hardrada (‘hard ruler’), invaded northeast England with a large Viking army, determined to wrest control of the kingdom; less than a month later, a Norman army under William landed in the south, driven by the same ambition.

      Battle Abbey, near the site of the Battle of Hastings on the Sussex coast, was begun by William the Conqueror after the Pope had told him in 1070 to do penance for all the English he had killed. It was completed after his death. The actual battlefield can still be seen on a sloping field below the abbey.

      Politics in early medieval England was decided by the sword. William had been promised the throne of England not only by Edward the Confessor, but, or so the Normans claimed, by Harold Godwinson himself. An ambitious and violent soldier, descended from Viking settlers, Duke William had already subjugated much of the area around his duchy of Normandy. In the summer of 1066, he summoned his own levies and those of his allies and vassals to mount an invasion of England. He had 700 boats built in a short space of time, but he still needed favourable winds. His army of 2,500 horsemen (with 2,000 horses), 1,000 archers and 3,000 infantry was forced to sit on the coast for 45 days before the wind finally changed. At dawn on 28 September, the army disembarked on the coast at Pevensey and awaited the English. The strength of William’s invasion force lay in the body of heavily armoured cavalry, by then commonly used in battles in France but rare in England, and also the archers, whose longbows and crossbows could rain arrows down on the enemy infantry. Almost all his men were trained soldiers rather than conscripted militia, with experience in using the bows, javelins and swords with which they were armed.

      One of fifty scenes from the Bayeux Tapestry, woven at Bayeux Cathedral in the late eleventh century on orders from William the Conqueror’s brother, Bishop Odo, depicts the Norman soldiers with their cavalry mounts. Hundreds of horses were transported across the English Channel from Normandy, but Duke William had to be sure of victory since there was no way to resupply his knights with mounts if the war became drawn out.
