Captain Sherer's record of service in the Peninsular War is second to none. A hard campaigner, he served with the 34th Foot at Busaco, Badajoz, Albuera, Arroyo Molinos, Vittoria and the Pyrenees, during which he was taken prisoner by the advancing French. In this, his service was no different to huge numbers of officers, a good number of whom left their memoirs to posterity. What marks out Sherer and his recollections is their quality.
