At 6:30 am on 25 September 1915, following a forty-minute discharge of gas and smoke the first waves of 15th British divisions clambered out of their trenches and began making their way across no-man’s-land - Scottish Highers History - Question 17 - 2022

Source A provides a detailed account of the events around the Scots’ involvement at the Battle of Loos. It highlights the remarkable advance made by the 15th (Scottish) Division, capturing significant points such as the village of Loos and Hill 70. Notably, it illustrates how the Scottish troops displayed courage and determination despite suffering heavy casualties. These points support the idea that Scottish forces were pivotal during this offensive.

However, while Source A effectively conveys certain aspects of their role, it does not delve deeply into the problems and challenges faced by the Scots. For example, it mentions their casualties but lacks specific figures or more extensive commentary on the general difficulties of trench warfare. Therefore, while it adequately showcases some contributions, it could be more comprehensive in addressing the hardships endured by the troops.
