The Brown Bull of Cooley is based in Connacht and Ulster. One day Maeve
and Ailill, the king and queen of Connacht, were boasting about their
possessions. The two began to fight. They then called their servants and told
them to count all their possessions. They were even except that Ailill had a
very fine bull and Maeve didn’t. Maeve then called one of her servants and
asked where can I get a bull as fine as Ailill’s. “The bull you are looking
for is in Ulster”, replied the servant. “The bull belongs to Daire Mac
Fiachra in Cooley”, the servant said. So Maeve sent messengers to Cooley to
ask if she could borrow the bull. Daire was delighted to help Maeve and ordered
a feast to be held. During the feast, one of the messengers boasted that if
Daire had not given the bull they would have taken it by force. When Daire heard
this he was furious he told the messenger “to tell their queen to get lost you
are not having my bull.” Maeve was determined to capture the bull. She
mustered an army and they marched to Ulster. It was wintertime and during the
winter the army of Ulster lay in a deep sleep. When only Cú Chulainn and the
boys of the Red Branch to defend Ulster met Maeve’s army. Cú Chulainn made an
agreement with Maeve that she would send one hero to fight him each day. Day
after day Maeve sent her heroes and one by one Cú Chulainn killed them.
One evening Cú Chulainn called the boys of the Red Branch and asked the
boys of them to defend Ulster. Then he fell into a deep sleep. Maeve decided
that this was the time to attack. While the battle was raging, she sent some of
her men to capture the bull. Cú Chulainn woke to find that most of the boys of
the Red Branch had been killed. By now, spring had returned and the spell of the
sea-witch had been lifted. The men of Ulster rushed to fight but Queen Maeve
retreated, driving the huge brown bull before her. When she arrived at the
castle she ordered that the bull should be put in a pen to keep him safe. When
Ailill’s bull, Finnbhennach, heard the brown bull roaring it charged. But the
Brown Bull of Cooley impaled Finnbhennach on its horns and white bull was killed
instantly. Then the bull returned and raging and bellowing it broke out of the
pen and thundered home to Cooley. But, no sooner had it returned home, its heart
burst and it died. So in the end neither Ailill nor Maeve was richer than the
other.
