NETD - Non-Effective Transfer Depot. No. 1 NETD was a unit that cleared personnel for return to Canada from the UK either for courses, on medical grounds, unfit for service, for release, posting to position in Canada, compassionate reasons or for escorting POWs.
was set up as Number One Transit Depot for handling thousands of medical and psychological cases during WWII and was referred to as 1 Non-Effective Transit Depot, or 1 NETD for short; an abbreviation that transient personnel soon modified to pet names such as "Not Enough To Drink, Nothing Else To Do, No Empties To-day, Non Efficient Tourist Depot and North Elstead Tourist Depot." (The fact that Tweedsmuir Camp stood south of Elstead seemed to be insignificant.) The camp was also responsible for clearing miscellaneous troops such as those transferring to the Royal Canadian Air Force, under age personnel and those who sought transfer to the USA Army in the UK.
Tweedsmuir Camp, situated between Elstead and Thursley to the north-west of Godalming.
