  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.

  No. 5 BATTLE OF HASTINGS

  14 October 1066

  * * *

  The most famous battle in all English history is undoubtedly the bloody daylong 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.

  Harold was on the other side of England. On 20 September at Fulford, near York, an army of 10,000 Vikings under Harald Hardrada and Harold’s brother, Tostig Godwinson, annihilated a force of perhaps 6,000 under earls Edwin and Morcar. Collecting levies from the south, Harold rode north from London, moving so quickly that his 5,000 men found the Viking invaders unprepared on both sides of the River Derwent, near a small village at Stamford Bridge. Charging the forces on one side of the river, the English soldiers slaughtered them all before crossing the narrow bridge and falling on the rest of the invasion force. Some 7,000 corpses littered the battlefield. Only 24 out of the 500 ships that had carried the Vikings to England were needed to take the survivors home.

  Harold’s victory ended any prospect in the near future of Scandinavian intervention in English affairs. If Hardrada’s invasion had been his only problem, the battle would be hailed as the start of a di
fferent English history. But messengers told Harold that another enemy awaited him in Sussex, ravaging the countryside, burning villages and towns and seizing their goods. He rode south with his tired and battered army and arrived at London on 6 October, where he was joined by other levies and his brothers Gyrth and Leofwine. Harold had at his command a mixed army of Anglo-Saxon nobility, their ‘housecarles’ or professional soldiers, and the trained militia, the fyrd. He was joined by a number of Danish mercenaries, or lithsmen. The housecarles and nobility wore long protective mail coats or ‘hauberks’ and carried spears, daggers and the deadly double-handed battleaxes that could cleave a man and horse in two. The fyrd were more lightly armed, and wore only thick leather jerkins. The principal tactic of Harold’s army was the shield wall, composed of lines of housecarles with heavy shields, forming a solid barrier of the toughest soldiery against which enemy attacks were designed to be broken by sheer physical power and the courage of the defending fighters.

  Harold moved south, arriving opposite William’s army on 13 October, and camped near the shallow Caldbec Hill. His army left their horses and proceeded early on the morning of 14 October to take up position at the top of a long but shallow slope, protected on both sides by swampy ground, where Harold set up a solid shield wall some ten or twelve men deep and perhaps 7,000-strong in total. Although he had successfully used a cavalry charge at Stamford Bridge, Harold chose to fight without cavalry and with very few archers. The shield wall, in contrast, was a primitive tactic to choose against William and left very little flexibility. The Norman army was drawn up in the early morning in a way that made the most of the mixed force William had brought with him. There were three sections: Flemish allies on the right, a Breton force on the left, and 3,500 cavalry and heavy infantry in the centre led by William. Throughout the day the Norman duke displayed a shrewd tactical judgement, making the most of his cavalry and his archers, probing to find a way to wear down the shield wall. Occasionally, as the legend of Hastings has it, his cavalry made feints as if to retreat, tempting Harold’s soldiers to run after them, only for the Anglo-Saxons to suddenly be surrounded and cut down.

  Battle was joined at around 9 a.m. Since the Normans were attacking up a slope, Harold had some advantages. His spearmen could throw more powerfully downwards, while William’s archers had to fire uphill, and his cavalry were forced to charge against the gradient. Most medieval battles were over in a couple of hours, but Hastings, contested by two battle-hardened and professional forces, lasted the whole day, at a terrible cost to both sides. At one point, the ferocity of the English stand broke the left flank of William’s force and threatened a more general retreat, rather than a ruse to lure the enemy into pursuit. Accounts of the battle have William removing his helmet to show he had not been slain and shouting to his men to hold firm and rally. They did so, just as a large group of English militia chased after them, thinking the whole army was in flight. The Anglo-Saxons were surrounded on a hillock and, despite a desperate effort to save themselves, each one was bludgeoned or speared to death where he stood.

  William then opted for attrition. Small groups of horsemen and heavy infantry attacked, taking casualties but also eating into the shield wall. Hour after hour of gory combat left all the men exhausted, desperate with thirst, and covered in wounds, great and small. The corpses were so many that it proved hard at times to fight on the slope made slippery with their blood. After six hours of slaughter, William could see that attrition was taking a greater toll of the enemy. He ordered a charge against the shield wall by all his surviving army. The Anglo-Saxon line gave way, and small groups of housecarles rallied round their lords as the Norman wave washed over them. Harold and his brothers were killed, the king so mutilated by the hacking Norman swords that his body could only be identified later by his mistress.

  There was no concept of surrender and Harold’s surviving men could be butchered where they were found. Some 4,000 of the Anglo-Saxon army died at Hastings, 2,000 of William’s men. William marched north to London, where he was crowned king in Westminster Abbey. England became a Norman province, united under one monarch. It is easy to be sentimental about Harold’s defeat, but he, like William, was just one of a long line of warrior noblemen, with Norse blood in their veins, who fought to the death for land and wealth. What made William different was his sharp military mind, shown in his ability to ‘manage’ the battlefield in an age of primitive combat. Crude though the fighting was, William’s victory rested on solid military understanding and bold leadership.

  No. 6 BATTLE OF ZHONGDU

  1215

  * * *

  There are few military leaders in world history with a more elevated reputation than the Mongol tribesman Temüjin, better known to history as Genghis Khan, or Chingghis Khan. Conqueror of half of Asia, his name became a byword for military ruthlessness and competence. No ambition was more vaunted or, in the end, more successful than his conquest of the vast northern Chinese Empire of the Jurchen Jin in the first decades of the thirteenth century. Few battles are more symbolic of the shift in the Asian power balance than the fight in 1214-15 to capture the Jin capital of Zhongdu on a site near present-day Beijing.

  Temüjin left few records and many of those who knew him well were illiterate. He was an outcast from his Mongol tribe following the death of his high-ranking father, and was said to have learned how to judge others and exploit their differences from his mother, Hoelun. He overcame the disadvantages of his youth and became a successful Mongol prince and warlord, his exploits and his political cunning attracting Mongol warriors to his side. Since the tribal rivalries of the Mongolian plain were a constant source of jealous friction and political uncertainty, there seems little doubt that Temüjin’s own astuteness, ruthlessness and shrewd judgement, as much as his success in almost constant fighting, explain his emergence as the dominant figure over the Mongol peoples. By 1206, he had become at last Genghis Khan, ruler of the Mongols, the name by which he is commonly remembered.

  In 1211, he embarked on the conquest of northern China, then ruled by the Jurchen Jin dynasty, which had captured the region from the Song some years before. His army probably totalled about 120,000, though the exact figures are not known. Mongol society was organized for military operations, since all men between the ages of fourteen and sixty were liable to serve when required. They learned to ride and to fire the powerful composite bows of the steppe horsemen from an early age; large hunting trips were used as surrogates for military training. Genghis Khan insisted on tough discipline, executing anyone who abandoned the fight or began to plunder before the order was given. The Mongol army was organized into units based on a decimal system: 10,000 men made a division, or tümen; each division was divided into units of 1,000, those into hundreds and the core unit was one of ten men. They were adept at ambushes and feints, and retained exceptional mobility.

  A print showing the Mongol emperor Genghis Kahn (c.1162-1227). After uniting all the Mongol tribes under his leadership, Genghis Kahn conquered the whole of northern China, ruled by the Jin dynasty, including the siege and conquest of the vast capital city at Zhongdu.

  The standard Mongol military practices, however, could not easily be deployed against large cities unless the garrison was foolish enough to sally out to fight. The conquest of Jin China required siege equipment, so Genghis recruited Chinese experts to supplement his large cavalry army. Much of the frontier area was conquered in rapid and devastating raids, but Genghis knew it was necessary to seize the Jin capital at Zhongdu to complete the conquest. The vast capital, surrounded by 15 kilometres (10 miles) of walls, 12 metres (40 feet) high, protected by 900 towers and a triple moat, was larger than any city the Mongols had captured. It was defended by an estimated 36,000 men, including 20,000 inside the walls and 4,000 stationed in each of four subsidiary towns where stores were kept, connected to Zhongdu by underground tunnels. Genghis and his army arrived outside the walls early in 1214. Two attempts to storm the city wer
e beaten off. On the first occasion, it seems likely that the Chinese let some of the attackers break through a gate, only to set fire to the street behind them, trapping the Mongols and slaughtering them. Genghis knew when to stop. A truce was called and the Chinese emperor paid over a Jin princess, 500 boys and girls, 3,000 horses and 10,000 liang of gold to get the Mongols to leave.

  Genghis almost certainly planned to return and when he heard in July that the emperor Xuanzong had decided to abandon Zhongdu as his capital and move it further south to Kaifeng, he took this as a sign of treachery and sent a large army of Mongols, Khitans and renegade Chinese to blockade the city. Blockade was not a usual Mongol strategy, but in this case it did what Genghis wanted. Xuanzong sent two large relief armies with supplies to break the blockade, but the first was surprised by a Mongol raid and its leader, the drunken Li Ying, was captured along with 1,000 wagons. The second suffered the same fate, ambushed at the River Yongding and destroyed by a much smaller Mongol force. The situation in Zhongdu became critical. One story has it that due to the shortage of stone or metal shot for the cannon in the city, among the first recorded uses of artillery with gunpowder if true, the ammunition was substituted with balls made of melted-down gold and silver. Genghis waited for the defenders and the population to starve. Cannibalism was later reported among both the besieged and the besiegers. The whole Mongol army now invested the city, preventing further supplies for the stricken capital. In late spring, the Jin commanders abandoned the city, Wanyen Fuxing choosing to commit suicide, while the army commander Mojan Chinchung smuggled himself at night through the Mongol lines, only later to be executed by the emperor in Kaifeng.
