HMS Earl of Peterborough

Most of the later bombardments by the Royal Navy were carried out by Monitors such as the Earl of Peterborough (two 12-inch guns, two 12-pdr and two 3-inch anti-aircraft guns). These monitors had been brought in to replace the more valuable battleships after they had been withdrawn. They were not very seaworthy in rough seas due to their shallow draft - The Earl of Peterborough drew only 2.9 metres (9 feet 7 inches), about a third of a battleship's or heavy cruiser's draft. Even the largest monitors drew only 3.6 metres (11 feet 8 inches), so could go in close to shore and also made it harder for torpedoes to hit.
The Navy played a part in the Suvla landings in August, and by then had improved some, but by no means all, of the techniques for naval bombardment. The capability to maintain a heavy weight of fire from seaward after the land artillery had been withdrawn was an important contribution to success when the time came to evacuate the peninsula.
