The RAN Bridging Train, (formed from members of the RAN Naval reserve), were embarked on the PORT MACQUARIE, for service in Gallipoli.
The submarine HMAS AE2, (LCDR H. Stoker, RN), penetrated the Dardanelles while the first ANZAC troops were storming ashore at Gallipoli.
After evading Turkish warships and mines, she broke through into the Sea of Marmara with orders to “Run Amok Generally” behind the enemy lines. AE2 sank a Turkish gunboat with a torpedo during her passage of the Dardanelles.
HMS SCORPION, (LCDR A. B. Cunningham, RN), patrolled off the beaches at Gallipoli.
The supporting destroyers were under orders not to engage shore targets in the initial stages of the landing, and cruised impotently off the shore while their comrades were unmercifully shelled by the Turks.
During the WWII Cunningham was C-in-C of the Mediterranean Fleet.
The RAN Bridging Train, (RANBT), was formed in Melbourne under the command of LCDR L.S. Bracegirdle.
The unit was to be a mounted engineering unit made up of RAN Reserve personnel who were unable to be employed in sea going ships. Originally it was planned the unit would operate with the Royal Naval Division, (RN Reservists employed as Infantry), on the Western Front, however the RANBT was later diverted to Gallipoli for service there.
LCDR Bracegirdle was selected as the Commanding Officer. Despite being a naval officer he had extensive experience in land warfare due to his service in China during the Boxer Rebellion, (1900), the Boer War, (1901-02), and the German New Guinea campaign, (1914-15).
The RAN’s first two submarines, AE1 and AE2, arrived in Sydney after a record voyage from England.
Within a year both submarines had been lost on active service, with AE1 lost during the campaign in German New Guinea, and AE2 lost in the Sea of Marmora during the Gallipoli Campaign.
