Maryculter is several miles from Aberdeen to the west.
May have been just to the south of Maryculter in heavily wooded area.
The likely targets would have been bridges over the River Dee. This would be a natural barrier for invasion troops trying to head North or South. There is a road between Stonehaven in the South that would allow bypassing of Aberdeen that the patrol would likely monitor / attack.
At Portlethen, there was a Chain Home Radar station, given the proximity to Maryculter, this could have been a target.
Given the close proximity to Milltimber, the names have been assumed based on the River Dee splitting the areas. Please also see Milltimber Patrol report for names.
