Anatomy of a disaster: the Bombay Docks Explosion

This narrative begins with a recollection of my father’s, a resident of a care home in October 2016. Dad recalled not only the name of the vessel on which he was a DEMS (Defensively Equipped Merchant Ship) gunner, but also the name of British ammunition ship SS Fort Stikine, the vessel that caused a massive explosion on Friday 14 April 1944 in the docks of Mumbai (called Bombay at the time).

This had remained in my father’s consciousness for many years not only because he was lucky to survive the disaster but because the explosions killed over 740 people and injured thousands more.

I examined our records in HO 187/739 and ADM 1/16065 to put together a timeline of the path to disaster and explain the inadequacies of the responses by all concerned.

The SS Fort Stikine, captained by Captain Naismith, was a 7,000 ton freighter. It reached Karachi on 30 March, where some of its cargo was unloaded, including crated spitfires, gold bars and 1400 tons of explosives including shells, torpedoes, mine signal rockets and incendiary bombs (most of which were for discharge at Bombay). Sulphur, cotton bales, timber, lubricating oil drums, turpentine, fish manure and resin were loaded to fill up the empty hold, flouting all normal rules.

The ship arrived in Victoria Dock on 12 April. Unloading started on the evening of 13 April, and then only of the fish manure and oil drums, some of which were leaking. This delay was the first of many errors that would lead to the catastrophic explosion.

Also on 13 April an officer of the Ministry of War Transport met with Chief Engineer Gow to discuss maintenance. The official sanctioned repair work but crucially this decision rendered the ship immovable except by tug.

Fort Stikine was one of 13 ships being worked that day; next door in Princes Dock were a further ten ships. At midday on 14 April the stevedores broke for lunch. So, as it turned out, did the civilian watchmen, a fact unknown to the captain, his officers or the two DEMS Gunners patrolling the ship.

At approximately 12.45 smoke was seen coming from the ventilators of No. 2 hold. The Commission of Enquiry later speculated that a stevedore could have climbed the ladder out of No. 1 hold, gone through the bulkhead door and descended into No. 2 hold for a cigarette.

A member of the police force also saw the smoke at 13:30 but dismissed it, believing that those on board would have the situation in hand. It was not until 13.45 that Mohamed Taqi, a foreman of a stevedore gang, observed the smoke in No. 2 hold. The alarm was raised by the crew and soon several hoses were directed into No. 2 hold. A standard precaution in the docks was to have a trailer pump with full crew standing by when a ship was being discharged. Seeing the stampede of people from the ship, the Section Leader ordered his Sub Leader to contact the Fire Brigade Control Room and give them a Number Two message (this would have alerted the Fire Control Room that the ship carried explosives).

Unfortunately the Sub Leader was unable to telephone the control; he instead broke the glass on the fire alarm, alerting the Fire Brigade to a fire – but not that it involved explosives! Consequently only two engines were despatched. Due to the density of the smoke the crew and firemen could not find the source of the fire and poured water in blindly.

At 14:25 Major Oberst, Ordnance Service, (Indian Army), arrived on board and asked for the stowage plan; he pointed out the extreme danger to the docks and suggested the ship be scuttled. Around the same time, Commander J.H. Longmire, Chief Salvage Officer of RINR (Royal India Naval Reserve), and Mr N. Coombs, O.C. of the Fire Brigade Service, arrived and requested that a large quantity of sulphur and detonators be removed from No. 1 hold. A meeting between the Captain, Chief Engineer and all above mentioned was held, but it turned out that the depth of water prevented flooding the holds. Nevertheless Oberst reiterated his fears to the ship’s captain.

By 14:45 the bulkhead dividing holds No. 1 and No.2 had become hot, and the men in No. 1 hold could hear ammunition exploding in No.2. The viability of introducing steam into the hold and battening down the hatches was discussed. Oberst, Longmire and Coombs also talked about Captain Naismith’s inability to reach a decision as to the scuttling of his ship.

Colonel Sadler, the dock’s general manager, arrived on board at 14:50 and advised that the ship be floated out of the harbour. As the engines were disabled, the only way this could be done would be with tugs. Sadler and Coombs argued about the merits of the former’s solution; Coombs was optimistic that the ship could be saved.

Two water tugs arrived shortly after 15:00 with additional water hoses. None of the high profile men on board felt that he could take overall command; neither of the two men ashore authorised to do so could be contacted. So three conflicting points of view existed on board: Captain Naismith wanted to save his ship, Colonel Sadler his docks and Coombs wanted the Fort Stikine to stay where it was so that his crew could concentrate on extinguishing the fire.

After 15:00 an attempt was made to cut a hole in the hull where a hot spot has appeared, but the equipment failed and there was a delay obtaining more. By 15:15 the floating bales of cotton had begun to ignite and some of the explosives had caught fire. Thick black smoke poured through the hatches, engulfing the firemen; burning pieces of cotton spewed skywards threatening other ships in the docks.

At 15:50 a giant flame shot out of the hold and many firemen were forced to abandon the ship. Captain Naismith gave the order to his men to abandon ship; he was last seen walking towards one of the harbour sheds. His body was never recovered.

At 16:06 there was a massive explosion. Fort Stikine was blown in two; its boiler, still intact, was found a half mile away. A huge tidal wave swept across the dock and ripped ships from their moorings, with one ship finishing astride a warehouse. At 16:33 a second explosion occurred, damaging or destroying the remaining ships in Victoria and Princess Dock, including the SS Tinombo, of which my father was a crew member. He survived by jumping into the dock. In Victoria Dock alone, 13 ships were lost.

Many people were killed outside the dock area by falling shrapnel and shells which exploded on impact. Approaching channels to the docks were littered with obstruction, and a vast land area was utterly devastated. It took four days to extinguish the main fire and for a  further two weeks smaller fires continued to smoulder in the ruins.

Overall, 231 people attached to the various services were killed, and another 476 injured. Outside the docks over 500 civilians were killed and a further 2,408 were injured. Thirteen ships were lost and 50,000 tons of shipping was destroyed, with a further 50,000 tons severely damaged.

    A fascinating insight into the events leading up to a WW2 maritime tragedy.

  2. M Conway says:

    A very informative and interesting blog about a little known disaster of the Second World War. Clearly mistakes were made by a series of officials in authority but above all the rules of transporting ammunition with other combustible materials was flouted!

  3. C Berry says:

    It must have been very interesting to speak to your father about this and then even more interesting for you to then go away and research this. It has been real privilege as a reader to get insight into what actually happened. Thanks for sharing what must have been in part a personal journey with your father.

  4. John Fieldhouse says:

    Hello Michael
    I came across your account by chance recognizing the maps and diagrams as having been taken from the Government of India War Transport Department Commission of Inquiry; First and Second Reports of the Bombay Explosions.
    I know this because I have both reports here together with a short handwritten account written by my father Raymond who felt and heard the first explosion from his fourth floor apartment in Shanti Kuteer on Marin Drive. My father was a sergeant serving in the Royal Corps of Signals but had been posted on Special (secret) Duty in Bombay in April 1944. He was sitting together with his corporal colleague and their first assumption was that either the city was being shelled by Japanese warships, bombed by aircraft, or that a stray shell – from earlier allied target practicing in the bay – had exploded. After half an hour the two of them hired a taxi to go to the Central Station so that the corporal could catch his train to Delhi. While passing along Marine Drive toward Chowpatti the two of them witnessed the second explosion and its aftermath from which – because of the secret nature of their work – they were prevented from assisting in rescue work.
    My father’s description is both chilling and beautiful. He describes the second explosion; ‘the golden ball swelled, turned heliotrope and flattened like a mushroom.’
    My father died over 35 years ago and though I have kept some of his ‘archives’ I never imagined that I would be able to share them with anyone! Many were killed in the explosions, even more were injured. Your father was fortunate to survive!

    1. Richard dias says:

      While doing research work on the dock explosion of 1944, I came across your comments. I just want to know the life of common people in Bombay during that troubled period. any help will be much appreciated you can send any reply to my email [personal details removed] tks.

    2. Sonal says:

      Is there a way that I can contact Mr John Fieldhouse?
      Thank you.
      Kind regards,

  5. John Fieldhouse says:

    As a postscript I might add that my father writes that the entire event was neither mentioned in the local newspaper the following day, nor in the days thereafter – weird!

  6. Bob Mossman says:

    I am wondering if there is a list of the names of everyone, who died, dock workers, firefighters, and civilians that can be referred to somewhere online. I am particularly interested in the fate of Ali Mahomed and his father Haji Mahomed. Ali may have been involved in some working role at dockside and his father was a businessman in the nearby neighborhood. Any help would be appreciated as I am working on a non-fiction biographical book in which Ali Mahomed is a one of the main characters. Many thanks. Bob Mossman

  7. Commander Mohan Narayan, IN (Retd), Mumbai, India says:

    A fascinating account of a catastrophe that rocked Bombay in the midst of a raging World War.I was particularly intrigued by the comments of Mr John Fieldhouse of 21 May 2017 as I once resided next door to, Shanti Kuteer, Marine Drive, Bombay (now Mumbai ) .
    I am doing independent research on the subject and have read John Ennis’s book on the subject. May I request you for some assistance. Would it be possible to access Part 2 of the Commission of Inquiry Report ( I already have Pt 1) headed by Sir Leonard Stone, the then Chief Justice of the Bombay High Court . It dealt with the events after the second explosion and discusses in detail about the damages the city of Bombay suffered due to the explosion. Any help would be greatly appreciated and duly acknowledged.

    1. Liz Bryant (Admin) says:

      Dear Commander Narayan,

      Best regards,


  8. Robin Godfrey says:

    I was a child of three and a half years living on Marine Drive with my mother, father being a Japanese POW in Sumatra. The explosion was one of my earliest memories, if not the first.

  9. Nic Brokenshire says:

    John Halpin Longmire, the Chief Salvage Officer mentioned in the story, was my 2nd cousin once removed. He was blown up in the first explosion and thrown a great distance by the blast where he was discovered, presumed dead and loaded on a cart. Many other poor souls were also loaded on the cart and John came round some time later surrounded by dead bodies. Fortunately, his cries for help were heard and he was recovered.

  10. Loy Rego says:

    Was ammonium nitrate one of the chemicals stored on the ship? I seem to remember hearing about this, but am now not sure after reading the accounts. Can anyone confirm or deny it.

    1. Matthew de Ville (Admin) says:

      It was TNT apparently, so not ammonium nitrate.

  11. Norman Todd says:

    The first I heard about this story was when my late mother mentioned the significance of the date in relation to a tiny detail (of the bigger story) that was significant to her. At the time in 1944 she was a newly qualified nurse at the JJ Hospital in Bombay. She said that the father of one of the other nurses had been brought in for treatment but sadly didn’t survive. Apparently he was a Captain of one of the ships involved in an explosion at the docks. As soon as I could, I searched the internet for details and stumbled across this horrific story. She had never mentioned this story before. In fact her limited recollection led me to think it was an isolated incident with unfortunate consequences for the Captain of a ship and his daughter. In reality she had been on the frontline providing medical care during one of the worlds’ major incidents.

  12. Cheryl Chown says:

    I heard about this disaster through my parents who were both in Bombay at the time and day of the explosion. My mother was with the F.A.N.Y.s and dad was a radio officer on a merchant ship in dock at the harbour . My father was knocked out on his ship by the explosion and lost everything he owned when his ship went down ,even the engagement ring he had purchased for my mother, intending to ask her to marry him. My mother told me it was an awful time for her and she had seen many horrific sights, the devastation in the area was so widespread .
    Mum always quipped that she only agreed to marry dad because he looked so sad and pathetic in the illfitting clothes scavenged from the merchant navy and the bandage around his head wound !! His reply was that he only proposed because hed been knocked senseless by the explosion. !!!
    I will try and find the name of his ship .

  13. Rajan Jayakar says:

    It is a fascinating narrative about a tragedy.Chief Justice of Bombay Sir Leonard Stone was appointed Commissioner to find the cause of tragedy,by Bombay Government,with assistance of experts.But report is not available.

  14. Leslie Green says:

    There is a little more information available in the George Medal citation awarded to my grandfather, William Edward Green.

    When the Bombay Explosion book was being researched, granddad decided to overtly omit the fact that he was married with three children at the time of the incident. My father (Owen Green) had been told (by granddad) to put on his scout’s uniform and assist his dad.

    Needless to say, when my father read the book and found out that he had been air-brushed out of history, it was very upsetting to him. Apparently granddad’s new wife would have been embarrassed to admit the existence of the earlier mixed-race family, including one son and two daughters (Olga and Rosemary).

    When I asked granddad about his George Medal (some 30 years ago), he simply replied that he had been around when they were giving them out!

    Apparently such traumatic events are not necessarily adequately talked about. It turns out that my uncle, Peter Pulford, who had been a signalman in the Royal Marines, was also present at the Bombay Docks explosion. We only found out several years after his passing, thereby missing the opportunity for him to ‘compare notes’ with my dad.

  15. Salman Dawood says:

    Where can I find a list of the casualties, Zakria Sait whos is my wifes great grandfather is thought to be among those who passed but I cant find his mention anywhere

  16. John Kaiser says:

    My father Bernard Kaiser was working for Tata Aircraft and was in a Godown at No2 Princes Dock collecting aircraft equipment when the explosions occurred. Here is his description…
    “Then disaster struck again. It was the 14th April 1944 when I went down to No. 2 Princes Dock with the Company’s new station waggon driven by our Indian driver. I had sent Mr. Gajria, our storekeeper, to the Godown in the morning to supervise the unloading of tools, equipment, and drums of plating materials from a ship, into the Godown. We had twenty-seven men in the Godown, it had thick stone walls and our materials were scattered all over by the time I arrived about 11.0 a.m. I worked with Gajria at a bench just inside the main doorway, checking the identification marks with my lists from the U.K. About 12 noon we heard the sound of fire engines and two engines sped past our Godown to the next dock, Victoria Dock. We took little notice at the time. I went for lunch and returned about 2 o’clock and continued the work. The driver parked the Ford station-waggon past the Godown main door but near the railway lines which ran the length of the dock area. We had located twelve drums of plating materials and a box of tools from other cargo, and other items were moved by the coolies, when suddenly there was a rush of air through the open doors; everything went very quiet, the wooden trusses in the roof started to collapse, then there was a terrific explosion which brought the roof crashing down on us.
    When the first rush of air occurred, I instinctively acted as we did during the Coventry and London air raids. I stepped quickly through the doors and lay down at the foot of the thick Godown walls. Fires started in all parts of the roofless Godown, star shells were shooting high into the sky from the direction of Victoria Dock and lumps of steel girders and plate flew over the railway line and landed on buildings four hundred yards away. There were minor explosions at intervals after the first big bang. The rush of air had ripped part of my shirt off and I was blackened by the dust and smoke.
    Gajria and other staff near the doors had followed my example. We both went into the Godown and searched for our men. Those outside were shocked and frightened as we all were. We told them to run across the railway line and get out of the dockyard but to shelter behind the low walls if they heard further explosions. They disappeared; the driver had bolted earlier. Gajria and I re-entered the Godown, fires were burning amongst the piled-up debris and in the remaining roof trusses. We rolled the twelve drums of plating materials outside, moved boxes of tools out and the typewriter we were using, all the time minor explosions were occurring at intervals. As we worked two sailors walked past holding each other. I stooped working and asked them what had happened, they didn’t see or hear me, they just staggered away holding each other up like drunks. As the burning roof looked dangerous, we had a last look round. We had done our best, our men had gone and we had saved what we could. It was time to get out. We climbed onto a pile of debris, there was an arm and a leg sticking out. I pulled first one, then the other. They belonged to two of our staff, Palal and Vaidya, and they came out of the debris like a pair of rabbits out of a burrow. They were not badly injured, just shocked and as we got them outside the rest of the roof collapsed.
    I was angry and dismayed. All my work in the U.K. and now this at the final end. I told Gajria and the other two men to scramble over the railway fence and shelter if they heard an explosion. My bad leg was painful. I had forgotten my stick in the excitement. I went to the station waggon, the key was missing but you pulled a knob to turn the engine. I drove the waggon on the starter motor as far as I could from the Godown and left it, I thought that at least this was safe. Then there was another major explosion, I lay down again against the Godovn wall, by this time I was alone. Part of a ship’s bridge, it must have weighed several tons, flew across the railway line, shells were shooting into the air in graceful arcs and landing in the residential area outside the docks. I thought that the three who had left several minutes earlier would be killed. I lay there for some time until the heat from the Godown was unbearable, I got my stick, climbed over the tall iron fence, crossed the railway line and entered the area devastated by the blasts. It was like no-man’s land. Bodies were strewn about, I passed six on my way out. I was dazed and shocked, but each time I heard an explosion I took shelter under the nearest low wall. After each minor explosion there was a shower of falling debris which would kill instantly if it hit you. It must have been another half-hour at this pace before I reached the dock gates. There I was taken to a First Aid post and attended to by a doctor and nurse. I was not badly injured. I was taken to an ambulance but broke away and found a taxi some distance away and went back to Bombay House.”

  17. Helen Budd says:

    I recall my father’s memory of this devastating explosion. He was also a DEMS Gunner on the SS Tinombo. He said on that day the Captain was celebrating his birthday and invited Dad and his mate to join him for drinks but they declined as Dad had a parcel to send home to Mum. They heard the explosion as they were leaving the docks.

    He said they spoke to some of their shipmates as they were leaving and subsequently met them at another port. They had survived by jumping in the water.

    Dad thought the ship’s captain was Dutch as was the ship.

  18. John Longmire says:

    My father was Commander J H Longmire , as his son , i was told about the Bombay Explosion Thanks to the internet ,many years later ,we are able to understand what happened on that day .I had just had my first birthday, In 1955 en route to Australia from the UK, Dad and I spent 6 weeks in Bombay during that time the current Harbour master told me and showed me where it all happened I was told that the explosion was a war secret I am very thankful my father survived and a big thankyou to all those who posted.

  19. Christopher Jones says:

    My grandfather – Victor M Bromley (RAMC) – was stationed in Bombay at the time of the explosion. Family memory states that he survived the blast wave because a wall forced the blast over his office, though much was destroyed. Apparently he did a lot to rescue and assist the locals. As a result he was honoured by them to attend a Sikh temple. I have a photo of him surrounded by mostly Sikh soldiers. But more than that I don’t know, as he was very reticent on the details, and is now long dead,

  20. HA says:

    My great uncle was killed while on the same ship as your father, the ss Tinombo. Interesting idea that your father on that picture might actually have known him. Are there any photographs in his pocession with crew mates?

    According to the info on this page, my great uncle was serving as head of machinery.

    It’s a Dutch source – he was Dutch, like I am.

    1. Michael Mahoney says:

      My father passed away in 2017 and there are only a few photos from this period of his life.

      The following records may contain your great uncle’s name: HO 187/739 and ADM 1/16065.

  21. Kathryn Knight says:

    My grandfather, George Daly, was an Established Smith and Local Chargeman working in the R.I.N. dockyard at the time of the explosion. I only found out he was there when I started researching his life. I don’t know how close he was or what he did in the aftermath.
    This information has been most helpful.

  22. John Sparling says:

    My father, Jim Sparling, was third engineer on the Empire Confidence in Bombay at the time of the explosion. His ship was damaged but not enough to prevent it from sailing to Australia to pick up grain for the population of Bombay, who must have suffered considerably at the time. Funnily enough, his Discharge Book is over stamped – “Renewal Book Issued Free – Original reported lost through enemy action”
    He rarely spoke about the war, so we’ll never know whether the loss of the original was due to the Bombay explosion.

  25. Linda Gibson says:

    I was just googling about the explosion for my son.
    My dad (102 this October) Lesley Mayes, was there when it happened too!!
    Crew was on deck getting a sub of wages to go into town when the explosion hit.
    They thought they was under attack. Then rushed off ship to help the wounded and dying. 💔💔. He couldn’t believe I found videos of it . His memories are very vivid.
    His brother Stan Mayes was well known on Ships Nostalgia.
    Take care 🌹
