Human activity on Dartmoor has a long history, with the first irrefutable evidence from the Neolithic period 4000-2500 BCE. More recently human activity is clear to see on any walk, including farming, industry, leisure and of course military. As well as the military camp near Okehampton, the three current firing ranges (Merrivale, Willsworthy and Okehampton) and existing facilities for military exercises, evidence for the MOD on Dartmoor can also be found in the numerous historic features of past military ventures.
The earliest of these date back to the early 1800s and coincide with the HMP Dartmoor in 1809. The battalion of soldiers manning the prison set up a firing range at Hart Tor to practise firing their muskets. Since then there are many phases of developing facilities for the MOD. These have occurred both for contemporary conflicts as well as changes in weapon technologies. Examples of both can be seen in the Rowtor area. To the north of the tor there is an area of later industrial activities, to the west of the road, that cuts through practise trenches for the Boer War in the late 1800s/early 1900s. To the south of the tor is the impressive target railway, and the associated anti tank emplacement for the range that were obviously developed for the new trials of tank warfare.
The location of the cache, which is within one of the extant trenches dug out, is part of the artillery range known as "F" Range. This range was constructed in the late 19th century with a linear target carrier system to provide more realistic scenarios compared to static targets. This carrier system was machine powered and there is were two engine sheds, that would have had electrical lighting, possibly to allow night firing. Into the 20th century "F" was also used for anti tank weapons training, and around the scheduled tramway to the west of this cache there are a number of firing points dotted around to provide different scenarios for the crews training on it. Towards the end of its use a further carrier was built, this one pulley and hand powered, that ran a curved course to again increase possible scenarios. Upon the closure of this range a target was relocated to nearby "H" Range and as a result all associated military features were made redundant.
