Wexford Harbour

Wexford Harbour (Irish: Loch Garman) in County Wexford, Ireland is the natural harbour at the mouth of the River Slaney. In earlier times, the area occupied by the harbour was considerably larger than it is today, up to ten miles (16 km) wide at its widest point, with large mud flats on both sides. These were known as the North Slob and the South Slob from the Irish word slab, meaning mud. It contained several islands, the large island of Beggerin was known to be a safe refuge for early Christian settlements.

Vikings arrived from Norway in 819 AD and founded the city of Wexford calling it Waes Fjord, meaning 'inlet of the mudflats', and the modern name has evolved from this. Over the course of about 300 years, the Norse settled in Wexford, intermarried with the local population and gradually converted to Christianity. They forged temporary alliances with Irish kings, sometimes fighting with other Norse towns; at other times, such as in 933 and 1161 they were attacked by the Irish. The Norse remained in control until 1169 AD when Wexford was attacked by a superior force of Norman and Irish soldiers. There was a short battle after which the Hiberno-Norse withdrew within the walls leaving their ships unprotected. These were set on fire by the attackers - this may have been the origin of the Wexford Town crest, the three burning ships.

Wexford became a major maritime port exporting fish, cloth, wool and hides. It was Ireland's leading fishing port in the 15th and 16th century exporting mainly to ports along the west coast of England and Wales. In 1642, the Dublin government in a dispatch from London described Wexford as "a place plentiful in ships and seamen, and where the rebels have set up Spanish colours on their walls in defiance of the kings and kingdom of England, and have gotten in from foreign parts great stores of arms and ammunition". This was only one year after the Irish Rebellion of 1641 when Flemish mariners were encouraged to use Wexford Harbour to attack British ships passing along the Irish Sea from ports Whitehaven to Bristol and even in the English Channel. Wexford Harbour was a marvellous base for operations; it was strategically located at the junction of the Irish Sea, the Western Approaches of the English Channel and the Atlantic Ocean. The difficult navigation of the harbour gave security to the locals, as larger attacking ships could not enter. The sandbanks and narrow channels did not present much difficulty to the Dunkirk frigates or the local shallow draft cargo ships.
