There is no hill sketching on this drawing, suggesting it is an intermediate version. Yellow lines represent the area that would be covered by the final plan. A triangulation diagram appears on the reverse of this drawing. This enabled the draughtsman to plot prominent features of the landscape. Major lines of communication are coloured yellow, following standard military cartographic convention.
