The date is written but there is no entry on this day – the retreat continues

Sir John French the Commander in Chief of the BEF [British Expeditionary Force] decided that the safety of his troops depended on his conforming to the movements of the French. It was agreed that the Franco-British Armies should fall back to the River Marne so the last stage of the Retreat began.
