8 August 1915:

This was a key day for the Scots Guards. They left the 7th division and joined the newly formed Guards Division.

The battalion diary provides additional colour. The inspection by General Capper took place at 2pm.
Following the parade and inspection the Battalion was played out by the Divisional and 9th Devonshire Bands and Pipers from 2nd Gordon Highlanders to 'a splendid farewell ovation'.

The battalion diary records the battalion being billeted at Mollinghem on the night of the 8th.

The battalion would march away from Bethune, and its surrounding area on 9 August.
The view above shows the fields between Bethune and Festubert in August 2015.

Probably not much changed.
