In 1942 No 102 Squadron re-equipped with Halifaxes and continued with aircraft of this type for the rest of the European war. It took part in each of the three historic 1,000-bomber raids in May/June 1942, and, later, in the battles of the Ruhr, Hamburg, and Berlin. It was well to the fore in the pre-invasion attacks on railway communications in Northern France and on the eve of D-Day sent 26 aircraft - the largest number it had yet dispatched - to bomb an enemy gun battery on the coast of Normandy. In September/October 1944, it undertook the transportation of petrol to Belgium for the Second Army and in just over one week carried 134,250 gallons without mishap. In the great day and night 1,000 - bomber attacks on Duisburg in the closing stages of the war some of its crews made two round trips within twenty-four hours.
