Norse Warfare: A Portrayal of Combat, Raids, and Plunder in the Viking Age

They came in waves from the barren lands of the north—young, energetic, and adventurous men looking for a fight. One can only imagine the fear and surprise the monks at Lindisfarne, the monastery of St. Cuthbert on Holy Island on the Northumberland coast in northeastern England, felt when sighting the Viking fleet of long-ships that suddenly appeared at the horizon. The monks were men of peace and had been living and working at this holy sanctuary since the sixth century, and could not fathom the harm and destruction they were about to witness. An attack on God’s church was not only unexpected; it was thought inconceivable that a siege on such a scale could be carried out from the sea: “This year came dreadful fore-warnings over the land of the Northumbrians, terrifying the people most woefully; there were immense sheets of light rushing through the air, and whirlwinds, and fiery dragons flying across the firmament . . . and not long after . . . the harrowing inroads of heathen men made lamentable havoc in the church of God on Holy Island, by rapine and slaughter.” 

The Vikings came over the North Sea and built their reputation as unconventional and fearsome warriors by focusing the attacks on the monasteries along the shores of the British empire. When the long-ships neared the coast, the monks went down to the water to greet the arriving strangers, but this was not a time to be gullible. Without warning, crazed Norsemen beached their ships, robbed the monastery of its treasures, wrecked and shattered the precious altars, and murdered the monks, leaving only blood and destruction in their path. By the time the sails of the Viking fleet disappeared over the horizon, the monastery stood in ruins. The situation was dreadful. If God would not protect the monasteries, then who would protect the rest of Britain? 

The raid on Lindisfarne in 793 has been credited with starting the Viking Age, but was preceded by an earlier appearance of the Norsemen in England, when a smaller fleet of three long-ships arrived at Dorset in 787. A Saxon tax officer, thinking the strangers were traders, asked that they face the king and pay tax. The Vikings responded with displeasure at the request and killed the tax officer: “And in his days came first three ships of the Northmen from the land of robbers. The reve then rode thereto, and would drive them to the king’s town; for he knew not what they were; and there was he slain. These were the first ships of the Danish men that sought the land of the English nation.” 

Most of these early raids comprised small parties of just a few ships, but laid destruction on the land so heavy that the victims truly felt it was punishment from God. These early attempts at pirating the monasteries and convents along the coasts of England, Scotland, Ireland, and Wales were ambitious, but they were also sporadic in nature, and the great raid on Lindisfarne came as a shock to most of the civilized world.  “[T]he calamity of your tribulation saddens me greatly every day,” wrote Alcuin of York in a letter to the Bishop of Lindisfarne upon hearing of the attack. The assault was so gruesome that Alcuin had to justify the occurrence by relating it to the sins of the people: “. . . when the pagans desecrated the sanctuaries of God, and poured our the blood of saints around the altar . . . truly it has not happened by chance, but is a sign that it was well merited by someone.” The Vikings, who embraced a polytheistic heathen religion that by Christian standards had few rules and moral values and encouraged bravery in battle, must have laughed in mockery at the monks, who in their stupidity thought their Christian god would protect them. 

The monasteries were targeted not because the Vikings were particularly concerned with exploiting the Christians, however, but because these holy sites were known to store great riches that were irresistible temptations to pirates. The monasteries were also poorly protected, at least by the standards of the Norsemen, because Europe’s organized armies were frequently involved in conflicts among themselves and preoccupied fighting wars in other parts of the country. When the Frankish, German, and English leaders tried to resolve their internal squabbles, the defense of the monasteries and coastal communities was neglected. Many towns were also built along the coasts for the purpose of being easily accessible to travelers and merchants from the sea. Their location made them soft targets vulnerable to piracy and gave the Vikings opportune moments to raid. It was a double-edged sword: Ease of access was an essential feature of a thriving community, but a thriving community was also a primary target for pirates. 

But the Vikings, or Norsemen, were not like other pirates of the sea who focused on raiding what was considered easy takes, namely the common undefended folks of society. Their strategy shifted piracy instead toward the places that housed the greatest treasures, namely the churches and monasteries. Many of these holy sites were purposely located where there was no harbor and where a ship generally could not reach, and had previously been considered safe against looting. The Lindisfarne monastery on Holy Island, for example, was not accessible by land and thought to be secure against attack. But its so-called strategic location was a minor nuisance that the Vikings overcame through the construction of their ships, which distinguishing features were speed and surprise. The ingenuity in ship design allowed the Vikings to sail up and down a targeted country’s coastline and handpick their prey one-by-one. The broad bottomed ships could be sailed in shallow waters and needed no harbor, so the Vikings could make landfall wherever they chose. In order to effectively defend against the attacks, a country must therefore protect its entire coastline, an immense task that was not possible to carry out, especially since military strongholds were generally located away from the coasts and there were seldom enough forewarning of the attacks to muster the forces in time. 

Likewise, the Vikings rarely traveled inland since their goal was to come away with booty and not to secure territory. Greater riches may have loomed inland, but venturing too far from the water would have defeated their prime source of strength, which involved attacking in small groups with speed and surprise while avoiding land warfare against stronger armies, and to leave as quickly as they had come. With the exception of short travels across terrain in order to get to the village or monastery they wanted to raid, and sometimes in order to transport the ship short distances on land from one waterway to another, long overland marches were generally avoided. Of course, quick entries and exits were only possible when operating in small groups. The raids were therefore often random, comprising just a few ships and in accordance with the spirit of the warriors of the time, who went wherever they pleased and took whatever they could. A huge fleet of several hundred ships, as will be discussed later, required a different strategy. Any Viking could arrange a raid and most men acted on their own initiative, but the great Norse leaders, such as Ragnar Lodbrok, Sven Forkbeard, and Olaf Trygvason organized some of the bigger and more memorable campaigns. These leaders frequently paved the way for their offspring to follow. 

The Vikings ruled the seas and had the capacity to reach any island or waterway, leaving the monks defenseless and unable to protect the treasures. Since the journeys originated in the little known Nordic countries, Europe’s population was generally not aware of the development of the ships and the planning and organizing of the raids. Worse, this was just the forewarning of a long and horrific reign of terror. It was only the beginning of nearly three centuries of unpredictable pillage, plunder, slaughter, and pestering of Britain, Scotland, Ireland, France, and the western Roman empire. As could be heard in the prayers of the French—Free us, oh Lord, from the frenzy of the Norsemen!—from this day, men, women, and children lived in fear, and stories went that half of the civilized world had fallen to the onslaught of these heathen madmen from the north. And so, the Viking Age had officially begun.
