The professional partnership between Foch and Weygand was close and fruitful, with Weygand operating as a highly competent subordinate able to translate Foch's instructions into clearer orders, analyse ideas, and collate information. Foch referred to Weygand with praise, believing that their views were practically identical. Weygand finalised the plans for the 9th Army's attack at the First Battle of the Marne and, in doing so, became one of the first staff officers to reconnoitre the battlefield from the air. Weygand supported Foch, who was appointed to coordinate the Belgian, British, and French forces in the northern sector, during the Race to the Sea and First Ypres. Weygand was promoted to full colonel in early 1915.
