A Tiger tank of Battlegroup Fehrmann was engaged in clashes with a number of Comet tanks of the British Third Battalion Royal Tank Regiment (3RTR) on 12th and 13th April 1945 at a bridgehead over the River Aller near the town of Essel. Documented accounts available on the internet all seem to draw on information provided in 'Tigers in Combat' but some of this information appears spurious. In summary: 12th April 1945: Tiger clashes with 3 Comets of 1st Troop A Squadron 3RTR. One of the Comets is knocked out. Tiger withdraws. 13th April 1945: Same Tiger, when advancing again towards the bridgehead, is knocked out by a 3RTR Comet commanded by Sgt Harding. Key 'words' in the various accounts are Tiger, Fehrmann, Aller, Drebber Stream. MY QUESTIONS: Where, exactly, were the clashes on 12th and 13th April 1945? I've looked at various current maps and Google Earth and have found the general area but, partly because the area is forest, and trees do change over the course of the odd 65 years etc (!), I'm finding it difficult to pinpoint the exact position. Does anyone have access to period maps or other information that could help me? Why do I need to know? Simple, my father was Driver of one of the Comets (T335335 'Celerity') involved in the clash on 12th April 1945.
