The impact of the First World War on the parish of Streatlam and Stainton is reflected in the memorials that commemorate the actions of those of the parish who went to serve in the conflict. An obelisk can be found in the village of Stainton in a walled garden area adjacent to the Village Hall. The hall itself contains additional war memorials dedicated to inhabitants of the village.

The Second World War left much more of a mark on the area with military camps being established at Barford and Streatlam, and also at Stainton though this was also used for the containment of POW's. Elsewhere there is also the crash site of a German Messerschmitt that was shot down by a Spitfire over Streatlam.
