The British Expeditionary Force was retreating across Belgium. The 5th Inniskilling Dragoon Guards reinforced by 18-pounder field guns served as a rear guard, deployed through the outskirts of Brussels. At noon German armored cars, motorcycle troops and a self-propelled gun raced past two tank troops and gained a road in the British rear area. The British cavalrymen found that the enemy was all around and now between them and their supporting artillery. . .
