it is unclear when moore returned to britain. some reports say after the prussian war, others that it was before the first world war and still another that it was at the start of the second world war. he moved to 56 wildwood road in hampstead, north london, where he died after a prostate operation at the age of 86. his grandson, john moore, says the whereabouts of his grave is unknown but may be in the area of the welsh harp reservoir near cricklewood in north london.
