His Majesty’s Australian Submarine AE2 was launched in the yard of Vickers Ltd at Barrow-in-Furness, England on 18 June 1913 by Mr W.H. Wharton. She commissioned at Portsmouth on 28 February 1914 under the command of Lieutenant Commander Henry Hugh Gordon Dacre Stoker, RN. Her crew of 35 comprised officers and ratings from both the Royal Navy and Royal Australian Navy and she was the second of two E Class submarines built for the fledgling RAN.

Accompanied by her sister submarine AE1, (Lieutenant Commander Thomas Besant, RN), the two vessels sailed from England for Australia on 2 March 1914. The voyage was undertaken in three phases. The first phase took place under the escort of the Royal Navy cruiser HMS Eclipse which remained with the submarines until they reached Colombo.

En route, Eclipse alternately took the submarines in tow to reduce wear on their engines.  In spite of this precaution, AE2 suffered a serious defect while under her own power when she lost a propeller blade, necessitating repairs in Gibraltar between 6-9 March. With repairs complete, the small convoy continued its passage via Malta, and Port Said before AE2 threw a second propeller blade 20 miles outside of Aden. On this occasion repairs were carried out at sea with the assistance of Eclipse. The submarine was trimmed down by the bows and two anchors and cable from Eclipse were lowered over the front of AE2 to bring the stern of the boat out of the water. With the assistance of divers a replacement propeller was then fitted, the entire evolution taking two days. The three vessels then continued on to Colombo where they arrived on 9 April 1914.

Five days were spent in Colombo allowing the crews of the submarines to get some respite from the cramped and hot conditions in their respective boats. The passage through the Red Sea had been particularly demanding due to intense heat. Often the temperature inside the boats rose above 100 degrees F and in an attempt to cool AE2, Stoker ordered her casing to be painted white in an attempt to reflect the intense sunlight.

From Colombo the second phase of the voyage began under the escort of HMS Yarmouth which shepherded AE1 and AE2 to Singapore where they arrived safely on 21 April 1914. In Singapore the submarines were met by the cruiser HMAS Sydney which assumed responsibility for them for the remainder of the voyage to Sydney where they arrived on 24 May, 83 days after leaving Portsmouth. A total of sixty days had been spent at sea and some 13,000 miles covered; a record for submarines at that time.

Service with the ANMEF

Following the outbreak of World War 1 in August 1914, AE2 and AE1 were ordered to join the Australian Naval and Military Expeditionary Force (ANMEF) assigned to capture the German colonies in New Guinea. Stoker and his crew took part in the seizure of New Britain, culminating in the capture and surrender of Rabaul on 13 September 1914 and the general surrender of the New Guinea territories on 22 September 1914.

A key duty assigned to the two submarines throughout the operation was to guard St George's Strait, lying between New Britain and New Ireland, and defend the RAN fleet from the approach of any enemy ships. It was during one such patrol on 14 September 1914 that AE1 disappeared with all hands. A search was ordered for the missing submarine using all available ships but after three days it was called off, with no trace of the ill-fated submarine being found.

Operations in Suva

On 4 October 1914 AE2  proceeded to Suva to join Admiral Patey's force comprising HMA Ships Australia (I), Sydney (I), Encounter, Warrego (I) and the French light cruiser, Montcalm. Patey was under orders to counter any threat posed from the German cruisers Scharnhorst and Gneisenau which had attacked the French Society Islands on 22 September and were still at large. Following three uneventful weeks based at Fiji, AE2's service in the Pacific came to an end when she was detached on 8 November with orders to return to Sydney, where she duly arrived on 16 November.

Return to the Northern Hemisphere

Following a brief maintenance period, AE2 departed Sydney on 19 December en-route for Albany in Western Australia where she joined the second convoy of Australian Imperial Force (AIF) troops assembling in King George's Sound. The convoy of 17 transports sailed on 31 December for Suez via Colombo. Following the destruction of SMS Emden by HMAS Sydney the previous month, there was no requirement for other escorting warships and whenever possible AE2 was taken in tow to reduce wear on her engines. On 28 January 1915 the convoy arrived in Suez following what was, for the crew of the submarine, a long and uncomfortable passage across the Indian Ocean, through the Gulf of Aden and Red Sea.

Service in the Dardanelles

In February 1915 AE2 joined a Royal Navy squadron based on the island of Tenedos in the Agean Sea. From there she operated in support of the unfolding Dardanelles campaign.

Prior to 25 April 1915, AE2’s part in operations was minimal, but that changed when Vice Admiral de Robeck, Commander-in-Chief (C-in-C), Eastern Mediterranean Fleet, approved plans presented to him by Stoker to attempt to force a passage through the 35 mile long, heavily fortified Dardanelles Strait and enter the Sea of Marmora (also spelt Marmara). If this could be achieved, enemy shipping transiting between the Bosphorus and the Dardanelles could be prevented from reinforcing and re-supplying Turkish troops on the Gallipoli peninsula.

All previous attempts by Allied submarines to pass through the strait had failed due to an effective sea denial operation mounted by the enemy. Minefields, fixed and mobile gun batteries, searchlight surveillance and patrolling Turkish warships, coupled with natural navigational hazards, had made the Dardanelles seemingly impenetrable. The C-in-C remarked that if Stoker and his crew were successful there would be ‘no calculating the result it will cause, and it may well be that you will have done more to finish the war than any other act accomplished’.

On the morning of 24 April the attempt began, however, the mission was soon abandoned when one of the submarine’s forward hydroplanes failed, necessitating AE2 returning to Tenedos to effect repairs. With repairs complete, and with a heightened sense of tension among her crew, AE2 set off to try again the following day.

25 April 1915

LCDR Stoker
AE2's commanding officer Lieutenant Commander H H G D Stoker.

Lieutenant Commander Stoker takes up the story:

'Having proceeded from the anchorage off Tenedos, I lay at the entrance off the Dardanelles until moonset and at about 2:30 am on 25th April entered the straits at 8 knots. Weather calm and clear. As the order to run amok in the Narrows precluded all possibility of passing through unseen, I decided to travel on the surface as far as possible.'

Throughout AE2’s passage, searchlights continually swept the strait but she avoided detection continuing unmolested until 4:30 am when gun batteries opened fire from the northern shore. Stoker immediately dived, beginning an underwater passage through the minefields. Mooring wires tethering the mines continually scraped along AE2's sides for the next half hour. Twice Stoker surfaced in the minefield to make navigational observations and at 6:00 am AE2 was within two miles of the Narrows at Chanak, submerged at periscope depth with the sea flat and calm. Forts on both sides of the Narrows then sighted her and soon opened heavy fire. Meanwhile, Stoker, watching through his periscope, observed a number of ships and quickly determined to attack what he thought to be a small cruiser of the Peik e Shetrek type.

'At a range of 3-400 yards I fired the bow torpedo, at the same moment ordering 70 feet in order to avoid a T.B.D. [torpedo boat destroyer] which was attempting to ram on the port side. As the vessel descended the T.B.D. passed overhead close, and the torpedo was heard to hit. As the cruiser, dead ahead, might be expected to sink almost immediately, I altered course a point to starboard to avoid becoming entangled with her. At the time I believed the vessel to be in the centre of the strait. About 4 minutes later I altered back to the original course, and ordered 20 feet. As the vessel was rising she hit bottom and slid up on the bank to a depth of 10 feet, at which depth a considerable portion of the conning tower was above water. Through the periscope I saw that the position was immediately under Fort Anatoli Medjidieh.'

The fort opened fire and for some minutes shells fell on all sides until efforts to refloat her succeeded. AE2 then slid back into the safety of deep water. The relief onboard the submarine was palpable but short-lived, for AE2 then grounded on the Gallipoli shore, again exposing herself to the enemy.

'Through the periscope I judged the position to be immediately under Serina Burnu, and further observed two T.B.D.s, a gunboat, and several small craft standing close off in [the] Strait firing heavily and a cluster of small boats which I judged to be picking up survivors of the cruiser. In this position we remained for 5 minutes'.

'As my vessel was lying with inclination down by the bows I went full speed ahead. Shortly afterwards she began to move down the bank, gave a slight bump, gathered way and then bumped very heavily. She, however, continued to descend and at 80 feet I dived off the bank. The last bump was calculated to considerably injure the vessel, and probably impaired the fighting efficiency, but as I considered my chief duty was to prove the passage through the Straits to be possible, I decided to continue on course.'

‘In connection with these two groundings, I have to report that the behaviour of the crew was exemplary. In these two highly dangerous situations it was only their cool and intelligent performance of their duties which enabled the vessel to be refloated’.

Shortly afterwards AE2 again rose to periscope depth where Stoker established his position as approaching Nagara Point. On all sides he was surrounded by pursuit craft and each time he showed AE2’s periscope the pursuing destroyers turned to ram. Consequently, in an attempt to shake off the enemy, Stoker bottomed the submarine on the Asiatic shore to await developments.

Throughout 25 April, AE2 lay in 80 feet of water while enemy ships continually searched overhead. Those of her crew who could be spared were ordered to rest but most found sleep impossible. On one occasion the AE2’s casing was struck by a heavy object being trailed along the bottom by one of the vessels above but fortunately it did not snag or critically damage the submarine.

At approximately 9:00 pm Stoker blew ballast tanks and surfaced having been submerged for over sixteen hours.  All signs of shipping had vanished and the opportunity was taken to recharge the submarine’s batteries and to send a signal to the Commander-in-Chief notifying him of the successful passage through the ‘Narrows’ and past Nagara Point .

By then, the air inside the submarine was foul and her crew swarmed on deck ‘eager to breathe the cool night air’. At approximately 11:00 pm, cloud cover shaded the moon, providing AE2 with an additional layer of concealment, and in the early hours of the morning it began to rain reducing visibility further.

26 April 1915

By 3:00 am the weather began to clear as Stoker and his crew continued their passage on the surface toward the Sea of Marmora before diving at dawn. As soon as light permitted, Stoker observed through his periscope, ‘two ships approaching, obviously men-of-war, one in front of the other’. Steering a parallel and opposite course to the enemy he approached before firing his port torpedo.

Only after making the attack did Stoker realise he had fired at the smaller leading ship, a cruiser, which successfully evaded his torpedo.  Finding it impossible to bring another torpedo tube to bear on the second ship, which he judged to be a battleship of the Barbarossa class, a further attempt was abandoned.

'I continued on course through [the] Straits, examined the Gallipoli anchorage, found no ship worthy of attack and so proceeded in the Sea of Marmora, which was entered about 9:00 am.'

About 9:30 am AE2 sighted four ships, but since only six of her eight torpedoes remained Stoker decided not to fire unless he was certain his target was a troop transport.

'With this intention I dived close to the foremost ship - a tramp of about 2,000 tons. Passing about 200 yards abeam of her I could see no sign of troops or ammunition; but as I passed under her stern she ran up colours and opened rifle fire at [the] periscope. I then dived over to the next ship and attacked at 400 yards with starboard beam torpedo. The torpedo failed to hit. I was unable to get within range of the other two ships’.

The remainder of that day was spent on the surface recharging batteries and making good defects.

Shortly after dark, AE2 was attacked by a small Turkish vessel while again attempting to establish wireless communications with the fleet. The attacks continued whenever the submarine attempted to surface during the night of 26/27 April.

27-29 April 1915

At dawn on 27 April, while still dived, Stoker sighted a ship escorted by two torpedo boat destroyers. Evading the escort, he manoeuvred into a firing position at 300 yards but this time the torpedo refused to leave the tube, possibly due to a faulty engine. In response, one of the destroyers turned to ram, forcing a hurried dive. Nothing else was sighted that day and in order to give the crew some rest, the night of 27 April was spent on the bottom in Artaki Bay.

In the early hours of the morning of 28 April, in dead calm weather, AE2 attacked another small ship escorted by two small destroyers. Again the torpedo missed its intended target and retaliatory manoeuvres by the Turkish warships precluded a second attempt.

At dawn on 29 April Stoker shaped course towards Gallipoli observing a gunboat patrolling the head of the Strait off Eski Farnar Point.

‘Dived under gunboat down Strait, and returned up Strait showing periscope to give the impression that another submarine had come through. T.B.D.s and T.B.s [torpedo boats] came out in pursuit, and having led them all up towards Sea of Marmora, I dived back and examined Gallipoli anchorage but found nothing to attack.'

AE2 then returned to the Sea of Marmora where Stoker later fired on a Turkish gunboat narrowly missing her. Later that afternoon, he rendezvoused with HMS E14 (Lieutenant Commander E.C. Boyle, RN) the second Allied submarine to successfully pass through the Dardanelles. The two submarines met at 5.00 pm off Kara Burnu Point and following a brief conference between the two captains, a subsequent rendezvous was arranged for 10:00 am the following day. On the night of 29/30 April, AE2 lay on the bottom, north of Marmora Island.

30 April 1915

Arriving at the rendezvous at 10:00 am on 30 April, Stoker sighted a torpedo boat approaching at high speed.

'Dived to avoid torpedo boat; whilst diving sighted smoke in Artaki Bay, so steered south to investigate. About 10:30 the boat's nose suddenly rose and broke surface about 1 mile from T.B. Blew water forward but could not get boat to dive. T.B. firing, got very close, and ship from Artaki bay, a gunboat also firing; flooded a forward tank and boat suddenly took big inclination down by bows and dived rapidly. AE2 was only fitted with 100 foot depth gauges. This depth was quickly reached and passed. Went full speed astern and commenced to blow main ballast. After some interval boat came back to 100 ft depth, so re-flooded and went ahead, but boat broke surface stern first.’

‘Within a few seconds the engine room was hit, and holed in three places. Owing to the great inclination down by the bow, it was impossible to see the T.B. through the periscope and I considered that any attempt to ram would be useless. I therefore blew main ballast and ordered all hands on deck. Assisted by Lieutenant Haggard, I then opened the tanks to flood and went on deck. The boat sank in a few minutes in about 55 fathoms, in approximate position 4 degrees north of Kara Burnu Point at 10:45 am. All hands were picked up by the torpedo boat and no lives lost.'

Thus AE2's game of hide and seek was brought to an end, and her commanding officer and crew were on their way to spend the next three-and-a-half years in a Turkish prison camp. Four ratings died in captivity the remainder were released following the Armistice in 1918.
