Operation Dragoon - Royal Marines
Unit/ Formation: HM Ships
Period/ Conflict: World War II
Date/s: 15 August – 14 September 1944
Operation Dragoon was the code name for the Allied invasion of Southern France on 15 August 1944.
The operation was initially planned to be executed in conjunction with Operation Overlord, the Allied landing in Normandy, but the lack of available resources led to a cancellation of the second landing. By July 1944 the landing was reconsidered, as the clogged-up ports in Normandy did not have the capacity to adequately supply the Allied forces. Concurrently, the French High Command pushed for a revival of the operation that would include large numbers of French troops. As a result, the operation was finally approved in July to be executed in August.
Hundreds of Royal Marines supported the operation serving aboard HM Ships, HMS Ramillies was one of many HM Vessels to support the landings. Ramillies carried out bombardments between 15 and 28 August.
On D-Day itself, Gunfire Support Group Alpha primarily engaged coastal batteries guarding landing sector Alpha, around the Gulf of St. Tropez. Ramillies fired ten rounds at the heavy battery south of St. Tropez at 06:15 and twenty-four rounds at the battery near Cape Camarat at 06:54. Thereafter there was little need for further support as the invading infantry moved quickly inland. On 17 August, Ramillies moved to the Sitka sector and bombarded German positions on the island of Port-Cros. Guided by a spotter aircraft flying from Quincy (CA-71), she scored six direct hits on the town's fort.
The ground forces fought their way west towards Toulon. Supporting fire from the bombardment force assisted French forces who captured half of the city, but batteries on the St. Mandrier Peninsula continued to hold out. It was decided that a determined effort would be made to destroy or capture the forts on 25 August and the day before, Ramillies, who had been ordered to Algiers, received orders to return to the assault area.
Arriving off Porquerolles at 14:00 on 25 August, she joined Lorraine and a number of cruisers. Confusion initially reigned and Ramillies did not open fire until 16:40, firing sixteen rounds before her targets were obscured by smoke. Recommencing fire at 18:38, she fired a further forty-six rounds, scoring several hits and silencing two batteries. Several batteries continued to hold out however, and on 26 August, the bombardment continued. Ramillies fired thirty-five rounds, scoring direct hits and observing no retaliatory fire.
On 27 August she fired forty-eight more rounds, of which at least thirty-four fell within 50 yards of her target batteries. The German gun crews surrendered the following day.
Ramillies was finally released from the assault area on 29 August.

HMS Ramillies (pennant number: 07) was one of five Revenge-classsuper-dreadnought battleships built for the Royal Navy during the First World War. They were developments of the Queen Elizabeth-class battleships, with reductions in size and speed to offset increases in the armour protection whilst retaining the same main battery of eight 15-inch (381 mm) guns.
15 Inch Guns at the Imperial War Museum
The now iconic 15 inch guns from HMS Ramillies and HMS Resolution outside IWM’s Lambeth Road building were installed and unveiled to the public in 1968.
The removal was carried out by Robert Wynn and Sons at a cost of £2,575 for the move and £700-£800 for mounting the guns. To minimise disruption, the removal from storage at Shoeburyness to IWM was carried out at night.
