On December 7, 1941, the Japanese attack on Pearl Harbor resulted in the deaths of 1,177 sailors and crew members aboard the USS Arizona (BB-39). While this was a major setback for the US Navy, the battleship was not in action but docked at Ford Island. However, the greatest loss of American lives at sea due to enemy actions during World War II occurred when the Luftwaffe sank the HMT Rohna, operated by the British India Steam Navigation Company, in the Mediterranean.
Construction of the HMT Rohna
The construction of the HMT Rohna started in 1925 when the British India Steam Navigation Company commissioned two new ships for its Madras-Nagapatam-Singapore route. Built by Hawthorn Leslie and Company at their Hebburn shipyard on the River Tyne, Rohna was launched in August 1926 and completed a few months thereafter.
Initially intended for civilian use, the vessel could accommodate 5,064 deck passengers, although new regulations later reduced that total to just 3,851. Even with the reduced capacity, Rohna could still transport more passengers than any other ship registered in the United Kingdom. Consequently, her commission as a troop transport during the Second World War was not unexpected.
Service during the early days of World War II
The HMT Rohna was sailing the Indian Ocean when the UK entered World War II. Largely operating unescorted and occasionally traveling as part of convoys, she ferried thousands of troops to different areas, including through the Suez Canal and between Bombay, Marseille, Durban, Mombasa and Dar es Salaam.
Rohna was involved in several important campaigns early on in the Second World War. She ferried troops throughout the North African Campaign, as well as during the invasion of Sicily, which ended in an Allied victory and resulted in the collapse of Italian Prime Minister Benito Mussolini‘s regime. Lastly, the vessel ferried troops during the Allied invasion of Italy.
The HMT Rohna transported a number of American soldiers
In November 1943, the HMT Rohna set sail with 1,981 American soldiers en route to India. Along with these troops, the ship was staffed by a mainly Indian crew and included British and Australian officers. The soldiers, predominantly from the 853rd Engineer Battalion, Aviation, the 322nd Fighter Control Squadron, the 31st Signal Construction Battalion, and the 44th Portable Surgical Hospital Unit, were tasked with building Boeing B-29 Superfortress bases in India.
To guard against possible enemy attacks, 18 soldiers on board the Rohna were designated to man the ship’s Oerlikon autocannons and QF 12-pounder 12 cwt naval gun.
Sinking of the HMT Rohna
On the morning of November 25, 1943, the HMT Rohna and four other troop ships departed Oran, in French Algeria. The next day, the convoy came under siege by a group of Heinkel He 177A Greifs, Junkers Ju 88s and torpedo bombers. While the convoy was defended by Free French Air Force Supermarine Spitfires, there were only four up against over 20 Luftwaffe-flown aircraft.
The He 177As were armed with Henschel Hs 293 radio-guided glide bombs, which they dropped on the ships below. The majority were unsuccessful in hitting their targets, as the way they were released made it difficult to accurately hit. The convoy fought back with their anti-aircraft guns.
Around an hour in, Rohna was struck by a bomb on her port side, becoming the only casualty of the skirmish. Many onboard were injured or killed, while several escaped and boarded lifeboats. In total, 1,138 were killed, of which 1,015 were American, and 782 reached the lifeboats. They were later rescued by the cargo ship Clan Campbell and the Auk-class minesweeper USS Pioneer (AM-105), who themselves were protected by the Hunt-class destroyer HMS Atherstone (L05).
Legacy of the sinking
Along with the 1,015 US personnel who died during the attack, another 35 later succumbed to their injuries, making the sinking of the HMT Rohna the largest loss of American life at sea due to enemy action in a single incident during WWII. The US government wasn’t transparent about what had happened. In January 1944, the families of those killed received a telegram that revealed their loved ones were missing. They received a follow-up a few months later, which said that those missing had been killed.
In February 1944, officials revealed to the press that there had been an incident that caused the deaths of over 1,000 American soldiers, but held back the total casualty numbers and the name of the ship until June 1945. While they admitted Rohna had been sunk by German bombers, they kept back details regarding the radio-guided glide bombs until the Freedom of Information Act was passed in 1967.

The reason behind the subterfuge? American officials didn’t want the German forces to know the explosives were effective. Since Rohna‘s sinking, a number of memorials have been dedicated to the men who lost their lives. They’re located in London, UK; Bronx, New York City, New York; Seale, Alabama; Chittagong, Bangladesh; and Mumbai, India.
