Patrick's Return to Ireland
There can be no doubt as to the time of St. Patrick's arrival in Ireland, or of the circumstances connected with it. The date of his arrival, 432AD, is proved by a concurrence of events - this point is agreed on by historians as well as by hagiographers (writer of saints lives). What this is based upon is that when Patrick came to it was during the ninth reign of Theodosius and the fourth year of Laeghaire, son of Nial. It is very probable that Patrick came directly to the North-Eastern Ireland, not on a mission to pagans, rather to minister as Bishop to an already established Christian Community
Patrick and his followers in their small boat were drawn into the Strangford Lough due to the strong tidal currents. This Lough was formally known as Lough Cuan in County Down and they landed at the mouth of the river Slaney, near to modern day Raholp. When they landed, according to Legend a boy saw Patrick and his followers, he thought that they were robbers or thieves, quickly informing his master Dichu that Pirates had landed in his territory. Dichu set his dogs on Patrick and his followers, however, when Dichu saw Patrick he became calm as Patrick spoke the words of the Psalm, Dichu no longer feared the man and his followers
Patrick able to communicate with Dichu, convinced him that he was a man of peace, eventually converting Dichu to Christianity. Resulting from this Dichu give Patrick a small barn for his first church in the Irish Sabbhall (and the English tongue Saul). Saul became one of the most important Christian sites in Ireland.
However the rest of Patrick's conversions were not going to be as straight forward as Dichu's. On Patrick's arrival he was anxious to go to Slemish to see Miliucc his former owner. He had hopes of converting him to Christianity . He made his way through Ireland to Slemish, Co. Antrim. Miliucc on seeing Patrick's arrival was terrified that Patrick would cause him harm or enslave him. And with that he killed himself by committing himself to flames. An ancient record adds: "His pride could not endure the thought of being vanquished by his former slave". Patrick was struck with horror on seeing his old master Milchu enveloped in flames.
On Patrick's return to Saul, Patrick learned that the chieftains of
Erin had been summoned to celebrate a special feast at Tara
by Leoghaire, who was the High King of Ireland. This would be a perfect
opportunity for Patrick to present himself before the assembly.
