The hidden remains of Sentosa’s big WW2 guns

Do note:

The photographs of the remains of Connaught Battery contained in this post were taken during a recent recce accompanied by a member of Sentosa’s staff. Do note that the area in which the remains are found is out of bounds. It contains a number of hazards and it is not only not advisable not to visit the area without the necessary permissions and supervision, you would also be trespassing if you do so.

The remains of Connaught’s No 3 Gun emplacement.

Hidden in the vegetation of Sentosa’s two easternmost elevations just a stone’s throw away from one of Singapore most luxurious residential quarters, are the remains of its guns from the era of the Second World War. The better known of the two elevations, is of course Mount Serapong, which has been made accessible through public tours. A second set of guns, three 9.2 inch guns, were placed on the neighbouring elevation. These went into action during the Second World War, and were turned north and north-west to fire towards advancing Imperial Japanese Army troops in the direction of the Causeway, Jurong and Bukit Timah. All available ammunition, a large proportion of which were armour piercing and therefore ineffective against the advancing foot soldiers, was used before the guns were spiked and destroyed on 14 February 1942 — a day before Singapore capitulated. What remains of Connaught Battery include the badly damaged No 3 gun emplacement, a Battery Observation Post and an underground magazine, a retaining wall of the underground structure and several ventilation and other openings.

Background to the development of Sentosa’s Coastal Defence Positions and Connaught Battery

For large parts of its history, Sentosa was not as tranquil an island as its name would suggest. The so-called isle of tranquility, was previously called Blakang Mati, a name that carries with it a suggestion of death or even violence, even if little seems to be known about the origins of a name that it was known by since at least the early 17th century.¹ Blakang Mati was also an island that has long had a reputation of being a pirates’ lair. This seemed to be the case as far as the 14th century, with the accounts of Yuan dynasty Chinese voyager, Wang Dayuan, describing what is now thought to be the waters in the area of the island as being infested with pirates².

While an air of tranquility may have descended on the island following the Honourable East India Company’s (EIC) entry into Singapore with its second Resident, Dr John Crawfurd, describing it as a “beautiful and romantic spot”³, the spectre of death seem to still hang over Blakang Mati. Outbreaks of “Blakang Mati Fever” occurred. These were “of so deadly a character as to carry off three quarters of those attacked”, prompting some of those who settled on the island to flee in “fear and horror”.

The threat posed by “Blakang Mati Fever” however, did little to stop the one square mile island from being turned into one of Singapore’s most heavily armed and fortified square miles. Suggestion were in fact made as early as 1843, for an infantry garrison to be placed on the island as part of a plan to defend Singapore. While little came out of this plan in relation to Blakang Mati, the threat posed by Imperial Russia through it establishing a base in 1872 at Vladivostok on land it acquired from China, and the fact that advances in naval shipbuilding had greatly improved the speed, range, armour, and armament carrying capability of warships, prompted the building up of a coastal defence system to protect the Singapore and New Harbour. Measures taken included the placement of coastal artillery batteries on Blakang Mati. By 1878-79, batteries with fortifications were established at Fort Blakang Mati East (renamed Fort Connaught in 1890 to commemorate the visit of the Duke of Connaught to Singapore) and Fort Siloso. This effort also saw an infantry redoubt built at Mount Serapong.

Blakang Mati’s coastal defence positions and armaments on Sentosa would see overhauls over the years. Among the upgrades was the setting up of a battery at Mount Serapong following a review undertaken in 1885 with Singapore’s growing importance as a coaling station ii mind. Another upgrade, made from 1907 to 1911, came in the wake of Japanese successes in the Russo-Japanese War. This saw the battery at Mount Imbiah added, which was completed in 1912 with Fort Connaught’s battery being decommissioned as a result of it. Imbiah Battery would itself be decommissioned in 1937, when a rebuilt Connaught Battery came into play. The battery, along with a battery at Mount Serapong, remained in service up to the time of the Second World War. The rebuilding of Connaught Battery resulted in the removal of all traces of the 19th century fortifications of Fort Connaught.

While the guns at Serapong seemed to have been damaged during Japanese air raids in January 1942, the three guns at Connaught Battery were turned northwards and were fired in the direction of the Causeway and later at advancing Japanese troops at Jurong on 11 Feb 1942 and Bukit Timah on 12 Feb 1942, expanding all the available ammunition, before being spiked and destroyed on 14 Feb 1942.

________________

¹ The first instance of the island being positively identified as Blakang Mati was through a map made by the Malacca-based Manual Godinho de Erédia. This was published in 1604 to aid in the discovery of the legendary islands of gold. In the map, the island is identified as “Blacan Mati” with the “c” being pronounced as a hard c.

² In Wang Dayuan’s accounts contained Daoyi zhilüe (島夷誌略) or “Description of Barbarians of the Islands”, he provides a description of a pirate infested “Longyamen” (龍牙門) or Dragon-Teeth Gate, which is now believed to have been a reference to the pair of rocky outcrops at Tanjong Rimau at the western end of Blakang Mati and across the waters at Tanjong Berlayer. Known as “Lots Wife” to the British, they were removed to widen the entrance to New Harbour (Keppel Harbour) in 1848.

³ Among the early uses of the island in the early days of EIC Singapore was the installation of a flagstaff on the island’s highest peak, Mount Serapong, in 1833. The island would also find use for the cultivation of pineapple, jackfruit, guava and chempedak with three villages being established. One was Kampong Ayer Bendera, which was named after the flagstaff. This was located at the foot of Mount Serapong and inhabited primarily by Bugis. There was also a Malay village in the area known as Kampong Serapong, while the third village was Kampong Blakang Mati, another Bugis village. A few Chinese also found their way to the island.

The real story behind Old Changi Hospital

The real story behind Old Changi Hospital, isn’t about what the place seems to have got an unfortunate reputation more recently for.  The former hospital, which has its roots in the RAF Hospital set up after the war in 1947, is a place that many who were warded or who worked there remember with fondness.

The hospital, with a reputation of being one of the best military medical facilities in the Far East, is also well remembered for the wonderful views its wards provided of the sea and that it was felt aided in rest and recovery.

Members of the public got to learn about the background to the hospital and how some of the basis for the more recently circulated myths are quite clearly false during a visit to the site as part of the Discovering Singapore’s Best Kept Secrets series of State Property Visits organised with the support of the Singapore Land Authority. More on the visit and the series can also be found at the links below.

The gun battery set up for the defence of Singapore at Pengerang

Hidden in the vegetation on a knoll just by the Tanjung Pengelih Jetty in Pengerang is the little that remains of a 6″ gun battery that was set up for the defence of Singapore in the 1930s. The battery was one of several that came under the Changi Command. Positioned at the southeastern tip of the Malay Peninsula, the battery, along with others at Pulau Tekong and Changi, protected the eastern approach to the Straits of Johor and thus the Naval and Air Bases constructed up the strait at Seletar. All that now seems left of the battery – the guns were destroyed by the British just before Singapore fell, at least from their accessibility to the public, are the positions where Defence Electric Lights or DEL’s were placed.

One of the DEL positions, with part of its roof collapsed.

DEL’s, powerful searchlights,  supplemented coastal artillery. They could be used to search for and pick out targets, a practice that apparently had been used by the Royal Artillery since the late 1800s. These searchlights would be mounted in fortified positions closer to the coast and housed in concrete emplacements . Essential electrical power would be provided by generators housed in well-protected engine rooms, often built deep into the terrain.

Such would have been the case with the searchlight positions in Pengerang. Its remnants include both searchlight emplacements and an engine room, as well as supporting infrastructure such as accommodation blocks and storage rooms. These are all placed on the small hill that lies in the shadow of Bukit Pengerang or Johore Hill, on which the two 6″ guns of the battery were positioned.

I managed to join a visit to the site over the weekend orgainsed by a grouping of urban exploration enthusiasts who collectively brand themselves as the Temasek Rural Exploring Enthusiasts or TREE. For the visit, the group had tied up with guides and representatives from several Malaysian organisations and groups. These were the Muzium Tentera Darat (Army Museum) in Port Dickson, the Yayasan Warisan Johor (Johor Heritage Foundation), the Malaya Heritage Group and the Jabatan Warisan Negara (National Heritage Department). We were also joined by a Soko Jampasri,  a Japanese researcher who is based in Bangkok. Soko brought with her a Japanese military account of the war, contained in a book published by the now defunct Imperial Japanese Army Academy.

Information provided by Kapten Muhd Zuraiman Abd Ghani of the Muzium Tentera Darat as well as members of the Yayasan Warisan Johor (Johor Heritage Foundation) and the Malaya Heritage Group, point to Pengerang, a remote and isolated corner of the Malay Peninsula, being among the last positions in Malaya to have been surrendered to the Japanese Imperial Army. The army’s arrival coming a week or so after Singapore’s 15 February 1942 fall and this allowed several members of the forces based there to attempt an escape to Batam, where they were to be rounded up by the Japanese. Those that remained at Pengerang were captured and sent over to Changi.

There was a little uncertainty if the guns at the position were fired at all in anger. Information provided in the Karl Hack and Kevin Blackburn’s “Did Singapore have to fall? Churchill and the impregnable fortress” point to them being used to fire at a junk on 11 February 1942. The guns might not have been used again and were destroyed on 14 February 1942 along with those at Sajahat, Ladang, Calder, Sphinx and Tekong as the loss of Singapore seemed imminent. The gun positions on Bukit Pengerang are now within the confines of the TLDM KD Sultan Ismail, the Naval Base now at Tanjung Pengelih, and it is not known if any traces of their emplacements are still around.

One of the structures that remain is one that greets the eye just around the bend in the road from the jetty – a machine gun pillbox. The pillbox, which is now decorated will Johor state flags and a strange collection of old items, is quite readily accessible and is one that takes me back to the days of my childhood. There were many such pillboxes found across the southern shores of Singapore up to the early 1970s and several at the Changi area, including one at Mata Ikan where I would have the holidays of my early childhood at, served as places of play and adventure despite the strong smell of rotting matter that accompanied an entry into them. Most were removed as the coastline was being pushed out during the reclamation efforts of the 1970s. One that is left, at Labrador Park, now has its openings sealed and there no longer is a possibility of an adventure in them.

Several other gun emplacements and positions remain intact, including the publicly accessible No. 1 gun emplacement at the Johore Battery in Changi, now topped by a replica 15″ gun as well some substantial remnants of the Faber Command positions in Blakang Mati. However, what is left now at Pengerang is especially of interest, as it is a reminder that the protection of the garrison island, even if it was to prove ineffective in the entire scheme of things, involved positions outside what we see today as the boundaries of Singapore.

The monster guns of the east

Tucked away in a forgotten corner of Changi is a reminder of one of three monster guns of the east installed as part of the coastal defences to protect the island’s naval base from an attack by sea. The reminder, the No. 1 gun emplacement of the Johore Battery and its underground network of support structures, topped by a replica of the 15 inch gun that once stood proudly over it, is in an area today dominated by the high fences of the area’s prison complexes that make it seem an unlikely site for a coastal defence gun.

The terrain and its surroundings would of course have been very different in the days when the guns were installed. The considerations for locating them in the area go back to the 1920s, when the British were in the midst of planning on turning Changi into a military base. How it came to be chosen is already well documented by Peter Stubbs on his Fort Siloso website (see: Johore 15-inch Battery) in which there is a wealth of information also on the battery and other coastal defence sites across Singapore.

The replica gun at the site today.

Named in honour of the then Sultan of Johor who had donated a substantial sum of money (in the order of £500,000) – much of which was used to set up the battery, the Johore Battery was one of several batteries of the Changi Fire Command, established to protect the entrance to the Tebrau Strait and the Naval Base. These also included 6 and 9,2 inch guns that were set up around the eastern tip of Singapore in an area that extended to Pulau Tekong and Pengerang in southeastern Johor. The 15-inch guns, installed in 1938, had a range of 21 miles.

Besides the Changi Fire Command, the coastal defences also included a Faber Fire Command to protect the port and the city of Singapore and a total of 29 large gun batteries were distributed between the two commands. The Faber Fire Command also included a Buona Vista Battery with two 15-inch guns.

The labyrinth above ground.

Much has been discussed on the effectiveness of the guns in the days that led up to the Fall of Singapore. It could be suggested that the coastal defences did served their intended purpose in deterring an attack by the sea. What is quite certain however, was that although the flat trajectory of the guns and their ammunition made them unsuitable for use over land, two working guns of the Johore Battery were trained to the north and west and fired a total of Johore Battery (Infopedia) in the defence of the island. An account of one of the gun’s use is found in a paper “The Story of the end of Johore Battery during the Battle for Singapore” based on interviews with Malcolm Nash, the son of Gunner William Nash:

Once the Japanese had commenced their attack my father stated that his gun was turned around so that it could fire to the north. I believe that he said that turning it round took 12 hours. My father was the gunner responsible for firing the gun and thought the firing to have been merely a morale booster to frontline troops, as the shells available had been designed to pierce ships’ armour. During his time at Changi Prison he said that fellow soldiers had commented that the shells had sounded like a train going overhead when they were fired.

After eighty shells had been fired it was noticed that the rifling had started to protrude from the barrel and a member of the Royal Engineers was consulted. His view was that the gun was no longer fit for action and if fired again would not have his named attached to it. The gun was fired once more which caused its destruction, and the oil tanks around my father to explode and bathe him in oil.

The same paper describes an account of a Japanese Colonel, who recounts the guns’ armour piercing shells producing craters 15-16 metres in diameter and 5-6 metres deep and that the guns most intense phase came during 10-12 February 1942 when they were used to shell the centre and west of the Singapore. The guns were said to have been destroyed on the night of 12 February 1942. Following the end of the war, the remains of the 300 ton guns (the barrel alone was thought to have weighed 100 tons) were sold for scrap.

Besides the emplacements, a labyrinth of underground structures – a trace of which can now be seen above ground, were also built in an around the guns, in part to allow ammunition to be fed to the guns – the shells were loaded to the guns using a hydraulic lift. It was these tunnels and the emplacement of the No. 1 gun of the Johore Battery that was rediscovered in April 1991 in an area that became the Prisons’ Abington Centre and was then turned into the Johore Battery historic site and unveiled on 15 Fenruary 2002.  The underground structures are currently unsafe and access to them is not possible.
