French privateer Renard of St. Malo.
30 guns, 150-200 men
Lost Holyhead Bay 1710, crew saved.

From Dublin Intelligence - Tuesday 19 December 1710

Captain Welsh, master of the Packet boat that brought over the last packets from England, and all the passengers, report that there was a French privateer of St Malo, a 30 gun ship, [which] was drove into Holyhead by the late storm, where, upon making the usual signal of great distress, and firing all the night time long, the said Captain Welsh took out two boats and boarded her, the stress of weather still continuing harder and harder upon them, and having snapt their cables, they were forced at last to run the ship up a sand bank near the shore side, to save the mens lives, which effectually was done, and the whole ship's crew saved, consisting of 200 and odd men, who were all sent to Beau-Maurice[sic] gaol. This privateer had taken several very rich and valuable prizes, and had several ransomers on board. In very little time after that all the men were brought on shore by the care and pains of the said Capt. Welsh, who very much ventured with great hazard his own and the boat's crews lives to relieve this stranger, the ship soon after staved all to pieces.

From Holyhead Maritime Museum:

The naval cannons outside Holyhead Maritime Museum were dumped overboard by French privateers who tried to hold Holyhead men hostage but were thwarted by a storm.

Cannon at Holyhead:

  Their ship flew British colours and fired its guns as a call of distress when it sailed into Holyhead Bay on a Saturday in 1710. Local customs officer Maurice Owen and his crew went to help, but once aboard they realized they'd been tricked. The ship was a French privateer known as Fox, heavily armed and with a crew of more than 150 men. Privateers were privately owned ships authorised by governments to attack enemy shipping.
  Mr Owen and his crew were stripped and interrogated about Holyhead's defences. The vessel anchored off Borthwen beach to await a ransom for the hostage's return. As if by divine intervention, a storm arose and felled the ship's masts. The crew had to jettison 14 large cannons to make the ship easier to handle. Now the crew fired the remaining guns in genuine distress, but the townspeople were too afraid to help. The ship eventually grounded on rocks between Borthwen and Penrhos point. On the Sunday morning, the hostages and privateers were removed by boat. Most of the privateers were jailed in Beaumaris, but 20 were sent to Dublin.
  Some of the cannons were discovered by divers more than a century later [1810-20, using a diving bell], during construction of the Admiralty Pier. When King George IV had an enforced break of journey in Holyhead in 1821, the town had insufficient firepower to deliver a royal salute, so the heavily corroded cannons were fired.
