According to Samuel Pepys, Carteret was responsible for presenting and recommending the first use of frigates in the Royal Navy, from blueprints of a Frenchman in Saint-Malo.

Andrew Marvell mocked his poor command of English, and Samuel Pepys remarked that his ignorance of even the most basic Latin phrases would cause a schoolboy to be whipped.

On the commencement of the Civil War, he retired from the Navy, and withdrew with his family to Jersey, where his uncle, Sir Philippe de Carteret, was the Bailiff and Lieutenant-Governor.

The Royalists managed to hold onto the twin fortresses of Mont Orgueil and Elizabeth Castle and soon were able to rout the Island's Parliamentarian supporters.

After the defeat of the Royalists on the mainland in 1645, Carteret afforded an asylum to the Prince of Wales (Charles Stuart) and other refugees of distinction within his government of Jersey, where he served as Bailiff (1643–1651).

[5] Carteret organised the Jersey Militia along parish lines, creating twelve distinct units each with 150 infantrymen under a captain, a lieutenant, as well as a few light guns.

Carteret also had a small private army made up of Royalist veterans, who had fled from England after the defeat of Charles I, and a collection of foreign mercenaries.

The naval commander was General-at-Sea Robert Blake, whose fleet included twelve warships and a further seventy supply ships and transports.

The fleet was sighted at dawn on the 20 October to the north-east of Jersey and remained anchored in St. Ouen's Bay all day, waiting for favourable winds in order to start disembarking their troops on the shore.

The castle was built on a rocky islet, which was about a mile off the coast, which meant that it was surrounded by the sea on all sides and made it difficult to be bombarded from the land.

On the night of 9/10 November, a mortar shell fell onto the roof of the old Abbey Church, which just so happened to be the building where the defenders had been keeping their munitions and gunpowder.

The shell exploded on the lowest storey of the priory and detonated the twelve barrels of gunpowder inside, which caused a massive explosion.

These men were quickly captured and interrogated by the parliamentarians, who provided Colonel Heane with valuable information on the state of the castle's fortifications.

Despite these setbacks, George Carteret was determined to hold out for as long as possible, and he proceeded to keep the King's Standard flying over Elizabeth Castle for nearly another month.

In that time, he received word from Charles II who had stated plainly that the French Government were unwilling to help, for fear of sparking a diplomatic incident with the English Commonwealth.

Sir George Carteret was allowed to take a single vessel, sail with all his possessions to France, and formally join the household of the exiled Charles II.

On the eve of the surrender, Sir George invited Colonel Heane to dinner and they met each other on the rocks at the foot of Fort Charles (Bastion a part of Elizabeth castle).

As Treasurer he was hard working and free from any suspicion of corruption, although his colleagues at the Navy Board complained that they found his accounts difficult to follow.

It was issued as a proclamation for the structure of the government for the colony written by the two proprietors, Lord Berkeley and Sir George Carteret.

"[18] George Carteret is seen as a divisive figure in Jersey, with some seeing him very much as swashbuckling local hero and others as a prolific slave trader who made his fortune through piracy and slavetrading.

Which apparently was also a family affair with his son James ‘collecting’ over 300 slaves from Africa for transportation to the West Indies during one of the company’s early voyages in 1663.

It’s estimated that 44,000 men, women and children died en route, with thousands of those who did survive arriving in the New World with the company’s initials branded on their chests."
