27th April
At 2001 hours DBST on 27 April, the first of a force of forty-three RAF bomber aircraft began to take off for a daring night operation against the German battleship Tirpitz, which lay hidden deep within the Norwegian fjords. The force consisted primarily of Handley Page Halifaxes and Avro Lancasters, aircraft chosen for their payload and range, and crewed by men who knew they were heading into one of the most heavily defended targets in occupied Europe. Even before reaching enemy territory, the dangers of such an operation were evident. Two Halifaxes and one Lancaster were forced to abandon the mission early due to technical faults, returning to base and leaving forty aircraft to press on alone across the North Sea.
The journey to Norway was carried out under conditions that were both advantageous and perilous. The night was illuminated by a bright, almost full moon, and the sky was completely clear of cloud. While this gave the crews excellent visibility for navigation and target identification, it also exposed them to German radar and visual detection, making them more vulnerable to interception and anti-aircraft fire. As the bombers approached the fjords, the stillness and clarity of the night gave way to mounting tension among the crews, who were fully aware of the formidable defences awaiting them.
The first phase of the attack began shortly after midnight. At 0006 hours, the leading Lancaster from 44 Squadron flew over the anchorage and released its 4,000-pound “cookie” high-explosive bomb. At that moment, the Tirpitz was clearly visible, sitting ominously in the fjord. However, the Germans reacted with remarkable speed. Within minutes, smoke generators—both from shore installations and specially positioned smoke ships—began producing a dense, choking cloud that spread rapidly across the water. This artificial fog soon engulfed the fjord, obscuring not only the battleship but also the surrounding landscape. What had been a clearly defined target became a near-invisible one, forcing subsequent crews to rely on guesswork and improvised aiming points.
The second phase of the operation saw the Halifaxes of 35 Squadron, followed by those of 10 Squadron, flying at dangerously low altitude into the fjord. By this time, the smoke screen had become so effective that the Tirpitz could no longer be seen at all. Crews had to depend on a distinctive outcrop of rock above the ship’s known anchorage position as a reference point, dropping their bombs based on estimated positioning rather than direct visual confirmation. This method, while brave, significantly reduced accuracy and increased the time each aircraft spent exposed to enemy fire.
Flying low in the confined space of the fjord brought its own hazards. The bombers were subjected to intense anti-aircraft fire not only from guns positioned on ships and along the shoreline below, but also from batteries placed high on the cliffs above them. This created a deadly crossfire, with shells bursting both beneath and above the aircraft. Tracers arced through the night sky, and explosions lit up the smoke-filled darkness, turning the fjord into a chaotic and lethal environment. Several aircraft were struck during their bombing runs, some crashing into the water or the surrounding terrain, their crews having little chance of escape.
Among those caught in the maelstrom was Wing Commander Guy Gibson Bennet, a senior and experienced officer involved in the operation. During the attack, his aircraft was hit by anti-aircraft fire while flying at low level through the fjord. Severely damaged and unable to maintain control, the aircraft crashed in enemy territory. Demonstrating remarkable determination and presence of mind, Bennet survived the crash and managed to evade capture. Making his way across harsh terrain and through occupied territory, he eventually reached neutral Sweden, where he was interned but safe from German forces. His escape became one of the most notable personal stories of the operation, illustrating both the जोखिम faced by aircrews and their resilience.
Despite the courage displayed, the cost of the mission was high. Of the forty aircraft that continued to the target, five failed to return to base. Some were lost to anti-aircraft fire over the fjords, while others may have crashed during the long return journey across the sea. The combination of strong defences, effective smoke concealment, and the inherent dangers of night bombing at low altitude meant that the results against the Tirpitz were limited. Nevertheless, the operation demonstrated the RAF’s determination to neutralise the threat posed by the battleship, which continued to tie down significant Allied naval resources.
