Answer 1

Queen Maeve of Connaught, jealous because her husband's possessions outmatched hers, resolved to capture the famous Brown Bull of Cooley. Cuchulainn, the greatest of all Celtic heroes led the defence of Ulster. The story of the Tain Bo Chuailgne introduces us to an aristocratic but brutal Iron Age culture where honour and valor were jealously guarded. Inspired by the bravery of Cuchulainn, the Ulster warriors repulsed the Connaught hordes, but before Cuchulainn himself had been slain fighting against overwhelming odds. The Bull of Cooley engaged the prized white bull of Connaught and both destroyed each other.

Answer 2

This is what i could find but does not fit in with your letters - sorry!

Queen Mebh was the Queen of Connaught in the time when Cuchulainn lived. It was she who initiated the war between Connaught and Ulster in the Tain. The war began when Mebh and her husband Aillil, compared their wealth and Mebh's assets were equal to her husband's except for a great white bull. She wished to better his wealth and sent her servant MacRoth to get the great Brown Bull of Ulster which belonged to a man called Daire. Daire refused her offers for the bull after he learned of her desperation and Mebh invaded Ulster.

Mebh was responsible for the fight between Cuchulainn and his best friend Ferdia by taunting Ferdia for not fighting his friend because of his cowardice. Cuchulainn eventually killed his best friend during a three day battle at the ford. After Cuchulainn spared her life during the first invasion of Ulster, she invaded again seven years later and her warriors en masses defeated Cuchulainn by force of numbers. When she was handed the heroes head, she turned away in disgust as her final victory over Cuchulainn was a poor one.
