CHAPTER V

THE VIKINGS IN IRELAND TO THE BATTLE OF CLONTARF (1014)

In the history of the Vikings in Ireland we have seen how the attempt

made by Turges to bring all Ireland under one ruler came to nought

by his death in 845. At first this seems to have thrown the Norsemen

into confusion and we hear of a series of defeats. Then, in 849, the

invasions developed a new phase. Hitherto while the Irish had been

weakened by much internecine warfare, their enemies had worked with

one mind and heart. Now we read of 'a naval expedition of seven score

of the Foreigners coming to exercise power over the Foreigners who

were before them, so that they disturbed all Ireland afterwards.' This

means that the Danes were now taking an active part in the invasions

of Ireland, and we soon find them disputing the supremacy with the

earlier Norse settlers. A full and picturesque account of the struggle

is preserved for us in the second of the _Three Fragments of Irish

Annals_ copied by Dugald MacFirbis. Unfortunately the chronology of

these annals is in a highly confused state and it is often difficult to

trace the exact sequence of events.

When the Norsemen first saw the approaching fleet they were much

alarmed. Some said it was reinforcements from Norway, but others, with

keener insight, said they were Danes who were coming to harry and

plunder. A swift vessel was dispatched to find out who they were, and

when the steersman called out to them inquiring from what land they

came and whether as friend or foe, the only answer was a shower of

arrows. A fierce battle ensued, in which the Danes killed thrice their

own number and carried off the women-folk and property of the Norsemen.

In 851 they plundered the Norse settlements at Dublin and Dundalk, but

in the next year the Norsemen attacked them in Carlingford Lough. At

first the Danes were defeated, but then their leader cunningly exhorted

his men to secure by their prayers and alms the patronage of St

Patrick, who was incensed against the Norsemen because of the many evil

deeds they had wrought in Erin. The battle was renewed and the Danes

were victorious. After the battle they made rich gifts to St Patrick

for 'the Danes were a people with a kind of piety: they could for a

time refrain from meat and from women.' After the fight we learn that

the Danes cooked their meat in cauldrons supported on the bodies of

their dead foes. The Danes now helped Cerbhal, king of Ossory, against

the Norsemen who were harrying Munster, and henceforward we hear again

and again how the various Irish factions made use of the dissensions

among the invaders to further their own ends.

Matters were further complicated by the fact that many of the Irish

forsook their Christian baptism and joined the Norsemen in their

plundering. These recreant Irish were known as the Gaill-Gaedhil

(i.e. the foreign Irish), and played an important part in the wars

of the next few years. The Gaill-Gaedhil were undoubtedly a race of

mixed Norse and Gaelic stock and we must not imagine that they sprung

suddenly into existence at this time. Long before this the Norsemen

and the Gaels must have had considerable peaceful intercourse with

one another in their various settlements, and in accordance with

well-established Scandinavian custom it would seem that many of the

Irish were brought up as foster-children in Norse households and must

soon have learned to accept their religion and customs. There was

also extensive intermarriage between Norsemen and Irish. The annals

speak of several such unions, the most famous being the marriage of

Gormflaith, afterwards wife of Brian Borumha, to Anlaf Sihtricsson,

while in the genealogies of the Norse settlers in Iceland at the end of

this century, Gaelic names are of frequent occurrence. One of the most

famous of the leaders of these 'foreign Irish' was Ketill Finn (i.e.

the White), a Norseman with an Irish nickname. These foreign Irish

fought either by the side of the foreigners or on their own account

and we have an interesting story telling how, when Vikings from Ireland

made an invasion of Cheshire (c. 912), Aethelflæd, the lady of the

Mercians, sent ambassadors to those Irish who were fighting on the side

of the invaders, calling upon them to forsake the pagans and remember

the old kindness shown in England to Irish soldiers and clergy.

The troubles between Norsemen and Danes were probably responsible for

the arrival in Ireland in 853 of Amhlaeibh, son of the king of Norway,

to receive the submission of the foreigners. This Amhlaeibh is Olaf

the White of Norse tradition. Olaf is represented as ruling together

with his brother Imhar (O.N. Ívarr). The annals are not very good

authority for the relationship of the Norse leaders to one another,

and it is quite possible that Ívarr is really Ívarr the Boneless, son

to Ragnarr Loðbrók. Under the strong rule of Olaf and Ívarr Dublin

became the chief centre of Scandinavian rule in Ireland, and the

Danes and Norsemen were to some extent reconciled to one another. The

Irish suffered great losses but some brave leaders were found to face

the Norsemen. Cennedigh, king of Leix (Queen's County), came upon a

party of them laden with booty; they abandoned the spoil and rushed

upon Cennedigh with angry barbarous shouts, blowing their trumpets

and many of them crying _nui, nui_ (i.e. probably, in the old Norse

speech, _knúi, knúi_, 'hasten on, hasten on'). Many darts and spears

were thrown and at last they took to their heavy powerful swords.

All was however of no avail and Cennedigh won a great victory. Less

fortunate was Maelciarain, 'champion of the east of Ireland and a

hero-plunderer of the foreigners.' He was expelled from his kingdom by

the Leinstermen, who envied him in consequence of his many victories

over the Norsemen!

The activities of Olaf and Ívarr were not confined to Ireland. In 866

Olaf paid a visit to Scotland, while in 870 both Olaf and Ívarr were

present at the siege of Dumbarton. If Ívarr is Ívarr the Boneless, he

must then have gone to England and taken part in the martyrdom of St

Edmund. In the next year both leaders returned to Dublin with a large

number of prisoners--English, Britons and Picts. In 873 Ívarr, 'king

of the Norsemen of all Ireland and Britain' died, and about the same

time Olaf returned to Norway, possibly to take part in the great fight

against Harold Fairhair at Hafrsfjord. The Danes seem to have taken

advantage of the removal of Olaf to attempt to throw off the Norse

yoke. Fresh fighting took place and the Danes under Albdann, i.e.

Halfdanr, king of Northumbria, were defeated on Strangford Lough in 877

with the loss of their leader.

After 877 the _War of the Gaedhil with the Gaill_ notes a period of

rest for Ireland, lasting some forty years. This is true to the

extent that no large fleets of fresh invaders seem to have come to

Ireland during this time--the Vikings were too busy elsewhere, both

in England and the Frankish empire--but there were occasional raids

from Dublin, Cork, Limerick, Waterford and other towns into various

districts of Ireland, and the Norsemen were often at variance amongst

themselves. Dissensions in Dublin were particularly violent and so

much did they weaken Norse rule there that in 902 Dublin fell into

the hands of the Irish. The Vikings were driven abroad, some going

to Scotland and others to England, where they besieged Chester (_v.

supra_, p. 57). In the year 914 all the old troubles were renewed.

Rögnvaldr, a grandson of Ívarr, fresh from a great victory off the Isle

of Man, captured Waterford, and two years later Sigtryggr, another

grandson of Ívarr regained Dublin. The Irish attempted resistance

under the _ardrí_ Niall Glundubh, but he fell with twelve other kings

in a fight at Kilmashogue near Dublin in 919. During the next fifty

years Ireland was a prey to ceaseless attacks by Norwegians and Danes

alike. Towards the close of the 9th century Limerick had become a

stronghold of the Norsemen in the west, and from there they made their

way up the Shannon into the heart of the country. Cork was settled in

the early years of the 10th century, chiefly by Danes, and from there

all Munster was open to attack. Waterford and Wexford, which stood

as a rule in close connexion with Dublin, served as centres of attack

against Leinster. The Irish made a stout resistance under able leaders

and Dublin was 'destroyed' more than once. First among these leaders

stands Muirchertach 'of the leather cloaks,' son of Niall Glundubh,

a hero who came forward about the year 926. His activities were

unceasing. He repeatedly attacked Dublin, took a fleet to the Hebrides

where he defeated the Vikings, gaining much spoil, and finally in 941

made a circuit of Ireland, from which he brought back as hostages many

provincial kings, including the Norse ruler of Dublin. More famous

still in Irish song and story was Cellachan of Cashel. He made war

against the Vikings in Munster and for a time had the Norse kingdom of

Waterford under his control. Similarly he conquered Limerick, and we

find him fighting side by side with Norsemen from both these towns.

During these fifty years the Norse kingdom in Dublin stood in close

relation with the Scandinavian kingdom of Northumbria. Rögnvaldr,

who died in 912, ruled there and so did his brothers Sigtryggr (d.

927) and Guðröðr (or Godfrey) (d. 934). The brothers left sons known

respectively as Anlaf Sihtricsson and Anlaf Godfreyson. The latter

took part in the great fight at Brunanburh and died in 939. Anlaf

Sihtricsson was destined to a longer career. He would seem to have

spent his early years in Scotland where he married king Constantine's

daughter. It is uncertain whether he fought at Brunanburh, but he

came to Northumbria in 941 and captured York. He was expelled from

Northumbria in 944 or 945 and retired to Dublin, and the rest of his

life was chiefly spent in fighting in Ireland. He was in close alliance

with the Norsemen in Man and the Western Islands, and was, for some

thirty years, the most powerful Norse ruler in Ireland. Then came the

first great blow to Norse rule in Ireland. In 980 Maelsechlainn II, the

_ardrí_, won a great victory at Tara over the foreigners of Dublin and

the Islands in which Anlaf's son was slain. The power of the kingdom of

Dublin was effectually broken. The Norsemen were compelled to liberate

all the hostages in their custody, to pay a fine of 2000 oxen and

to remit the tribute which they had imposed on all Ireland from the

Shannon eastwards to the sea. Anlaf abandoned his authority and retired

on a pilgrimage to Iona, where he died in the same year an inmate of

its monastery.

In the meantime events, fraught with important consequences for

Norse rule in that country, were gradually developing in a distant

quarter of Ireland. In the province of Munster the Dalcassian line

of princes first comes into prominence about the middle of the 10th

century, and the two most famous of these princes were the brothers

Mathgamhain and Brian, commonly known as Brian Borumha. Together

the brothers conquered Munster in spite of the support given to the

Irish by the Viking settlers, and when their success aroused Ívarr,

the ruler of Limerick, they attacked him and won a great victory at

Sulcoit near Tipperary (968). Limerick was captured, Mathgamhain died

in 976 and Brian was soon acknowledged king of all Munster. He next

became master of Leinster, but his rapid advance brought him into

conflict with the _ardrí_ and by a compact made in 998, Maelsechlainn

practically surrendered the southern half of Ireland to Brian. The

ruler of Dublin at this time was Sigtryggr of the Silken Beard, son of

Anlaf and Gormflaith, sister of Maelmordha, king of Leinster. In 1000

Leinster with the support of the Norsemen in Dublin revolted, but Brian

defeated them and captured Dublin, giving his daughter in marriage

to Sigtryggr and himself marrying Gormflaith. In 1002 Maelsechlainn

submitted to Brian and the latter became _ardrí_. There followed twelve

years of peace, but Brian's marriage with Gormflaith was his undoing.

Quarrelling with her husband, she stirred up Maelmordha of Leinster

against him. An alliance was formed between Maelmordha and Sigtryggr,

and Gormflaith dispatched embassies to all the Viking settlements in

the West, summoning them to the aid of Sigtryggr in a great fight

against Brian. Sigtryggr secured the help of Earl Sigurd of the

Orkneys and North Scotland by promise of the kingship of Dublin. Ships

came from all parts of the Viking world, from Northumbria, from Man

and the Western Islands, from Scotland and the Orkneys, and even from

Iceland. Dublin was fixed as the trysting-place and Palm Sunday 1014

was to be the time of meeting. Brian mustered all the forces of Munster

and Connaught and was joined in half-hearted fashion by Maelsechlainn,

who was really waiting to see which way the fortunes of war would turn.

Brian advanced into the plain of Fingall, north of Dublin, and the two

armies faced one another at Clontarf all Passion week. The Norsemen had

learned by magic incantations that if the fight took place before Good

Friday their chiefs would perish and their forces be routed, while if

the fight took place on Good Friday Brian himself would perish but the

Irish would win the day. So they waited until the Friday and then made

their attack. The fight was long and the slaughter was terrible. Brian

and Sigurd were themselves numbered among the slain. In the end the

Norsemen were defeated and Maelsechlainn completed their discomfiture

when he cut down the fugitives as they tried to cross the bridge

leading to Dublin and so reach their ships. No fight was more famous in

Irish history and it seems to have appealed with equally strong force

to Scandinavian imagination. Clontarf and Brunanburh are the two great

Viking battles which find record in Scandinavian saga, and in the story

of Burnt Njal[8] we have a vivid account both of the actual battle and

of the events leading up to it. Yet more interesting perhaps is the old

lay preserved to us, the _Song of the Valkyries_, who that same day

were seen in Caithness riding twelve together to a bower where they set

up a loom of which men's heads were the weights, men's entrails the

warp and woof, while a sword was the shuttle and the reels were arrows.

They wove the web of war and foretold the fate of king Sigtryggr

and Earl Sigurd as well as the sharp sorrow which would befall the

Irish[9]. The Norse world was full of this and like portents and there

can be no question that the Vikings were themselves conscious that the

battle of Clontarf marked a very definite epoch in the history of the

Vikings in the West and in Ireland more particularly. The Norsemen

remained in possession of their cities, Sigtryggr continued as king

of Dublin, but gradually the fortunes of the Norse settlers tended to

become merged in the history of the nation as a whole and there was no

further question of Scandinavian supremacy in Ireland.
