The Army came to Aldershot in the 1850s. Before that the town was no more than a village. Much of the surrounding heathland in the area stretching from Farnborough across to Fleet and Aldershot was taken over. The growth was remarkable and Aldershots population increased year on year and with it the prosperity of the town. In latter days the Army has decreased considerably in size and that has had a severe economic knock on effect.
If you need to research the Army Records you will find they are mainly kept at the National Archives in Kew.
The WW1 Medal Roll Index at the National Archives is now searchable online. For those of you looking for WW2 Records you will need to write to the Ministry of Defence
