A period plan of the siege and battle of Kinsale, 1601

The Battle of Kinsale

The Gaelic world ended on a winter morning half an hour from Cork. At Kinsale, the harbour town twenty-five kilometres south of the city, the old Irish order made its last stand on Christmas Eve 1601 and lost it inside an hour. The battle decided who would rule the whole island for the next three centuries, and its shockwave reached straight into Cork, where a nervous English garrison threw up the first Elizabeth Fort within months. Every star fort in the county is, in the end, a reaction to that one morning.

The Spanish gamble

By 1601 the Nine Years' War had pushed English power back across much of Ireland. The Gaelic lords Hugh O'Neill of Tyrone and Red Hugh O'Donnell of Tyrconnell were winning in the north, fighting the war their way, from woods and bogs and river crossings, never letting the English catch them in the open. Then Catholic Spain sent the help O'Neill had been begging for. A force of around three and a half thousand soldiers under Don Juan del Águila landed in September 1601, not in the rebel north where it was needed, but at Kinsale, on the far southern coast, about as far from O'Neill as it was possible to get. The English commander Lord Mountjoy marched south and put the Spanish under siege inside the town. To save their allies, O'Neill and O'Donnell had to do the one thing they had spent nine years avoiding. They marched their armies the length of Ireland in midwinter and went to meet the English in open country.

Christmas Eve, 1601

The two Irish armies reached Kinsale in December and caught Mountjoy between themselves and the besieged Spanish, cold, sick and short of food. It should have been enough. Before dawn on 24 December they advanced in the dark to link up with the Spanish, and the plan fell apart almost at once. The columns lost each other in the night, arrived in the wrong order, and were still forming up in the open when the English cavalry hit them. The kind of battle the Gaelic lords had always refused to fight became a rout in under an hour. The Spanish in the town, watching for a signal that never came, did not sally out. Nine days later they surrendered on terms and sailed home.

The Irish had marched hundreds of miles in the worst of the winter, arrived hungry, and lost the one pitched battle they could not afford. O'Donnell sailed to Spain to plead for another army and died there within the year, aged twenty-nine. O'Neill made his way back north through a country turning against him, held out for another fifteen months, and submitted at Mellifont in March 1603, six days after Elizabeth died, a fact his enemies were careful not to tell him until he had signed. The cause they had carried for nine years finished in a single morning outside a Cork harbour town, and the Gaelic order that had run much of Ireland for a thousand years went down with it.

"An hour's fighting outside a Cork harbour ended four hundred years of Gaelic Ireland."

The long shadow

Kinsale broke the back of the Gaelic resistance. In September 1607 O'Neill, the new O'Donnell and ninety of their followers boarded a ship at Rathmullan in Donegal and sailed for the continent, the Flight of the Earls, leaving Ulster open to the plantation that followed. For Cork the lesson landed straight away. The Crown had watched a rebel army and a Spanish fleet arrive on its southern coast within a few miles of the city, and it wanted the port held down for good. In 1601 it raised the first fort on the rock above the south channel, the earthwork that became Elizabeth Fort. Charles Fort at Kinsale followed later in the century. Every time you look up at a star fort in this county, you are looking at the fear that Christmas Eve left behind.
