In Barbara W. Tuchman's "The Guns of August," General Joffre's strategy relied heavily on the British Expeditionary Force (BEF) to maintain control of the territory between Lanrezac and the emerging Sixth Army. This coordination was crucial for the success of Joffre’s broader plan during the military operations. The British troops were to act in accordance with the overall retreat, ensuring no gaps formed that could be exploited by the enemy.

Once the BEF reached the Somme region at St. Quentin, Joffre expected them to establish a strong defensive position. This strategy highlighted the importance of unity and timing in military maneuvers, as the BEF’s actions were critical to the effectiveness of the French forces in repelling the advancing enemy and stabilizing the front lines.
