Leinster, was the chief commander of the Fenian warriors, and his
great actions, strength and valor are celebrated in the Ossianic
poems, and various other productions of the ancient bards; he is
called Fingal in MacPherson's Poems of Ossian; but it is to be
observed that these are not the real poems of Ossian, but mostly
fictions fabricated by Mac Pherson himself, and containing some
passages from the ancient poems. Fionn had his chief residence and
fortress at Almhuim, now either the hill of Allen, near Kildare, or
Ailinn, near old Kilcullen, where a great rath still remains, which
was a residence of the ancient kings of Leinster. The Fenians were the
chief troops of Leinster, and were Milesians of the race of Heremon;
and their renowned commander Fionn, according to the Four Masters, was
slain by the cast of a javelin, or, according to others, by the shot
of an arrow, at a place called _Ath Brea_, on the river Boyne, A.D.
283, the year before the battle of Gaura, by the Lugnians of Tara, a
tribe who possessed the territory now called the barony of Lune, near
Tara, in Meath; and the place mentioned as Ath Brea, or the Ford of
Brea, was situated somewhere on the Boyne, between Trim and Navan.
In the reign of king Cairbre Liffeachair, son of the monarch Cormac,
the Fenian forces revolted from the service of Cairbre, and joined the
famous Mogh Corb, King of Munster, of the race of the Dalcassians.
After the death of Fionn Mac Cumhaill, the Fenians were commanded by
his son Oisin or Ossian, the celebrated warrior and bard; and at the
time of the battle of Gaura, Osgar, another famous champion, the son
of Oisin, commanded the Fenian forces. The army of Munster, commanded
by Mogh Corb, a name which signifies the Chief of the Chariot, and by
his son Fear Corb, that is, the man or warrior of the chariot, was
composed of the Clanna Deagha and Dalcassian troops, joined by the
Fenians and their Leinster forces; and it is stated in the Ossianic
poems, and in Hanmer's Chronicle, from the Book of Howth, that a great
body of warriors from North Britain. Denmark and Norway, came over and
fought on the side of the Fenians at Gaura. The army of the monarch
Cairbre was composed of the men of Heath and Ulster, together with the
Clanna Morna, or Connaught warriors, commanded by Aodh or Hugh, King
of Connaught, son of Garadh, grandson of Moraa of the Damnonian race.
The Munster forces, and Fenians, marched to Meath, where they were met
by the combined troops of the monarch Cairbre, and fought one of the
most furious battles recorded in Irish history, which continued
throughout the whole length of a summer's day. The greatest valor was
displayed by the warriors on each side, and it is difficult to say
which army were victors or vanquished. The heroic Osgar was slain in
single combat by the valiant monarch Cairbre, but Cairbre himself soon
afterwards fell by the hand of the champion Simon, the son of Ceirb,
of the race of the Fotharts of Leinster. Both armies amounted to about
fifty thousand men, the greatest part of whom were slain; of the
Fenian forces, which consisted of twenty thousand men, it is stated
that eighteen thousand fell, and on both sides, thirty thousand
warriors were slain. In the following year, Hugh, king of Connaught,
according to O'Flaherty's Ogygia, defeated the Munsters forces in
battle at Spaltrach, near the mountain Senchua, in Muscry, in which he
slew Mogh Corb, king of Munster. The tremendous battle of Gaura is
considered to have led to the subsequent fall of the Irish monarchy,
for after the destruction of the Fenian forces, the Irish kings never
were able to muster a national army equal in valor and discipline to
those heroes, either to cope with foreign foes, or to reduce to
subjection the rebellious provincial kings and princes; hence the
monarchy became weak and disorganized, and the ruling powers were
unable to maintain their authority or make a sufficient stand against
