The mayors, assistant mayors, and other officials of Candor and Lagny had been carried off by the Germans, but owing to the rapidity of retirement many women and children had been left behind. All over thirteen were compelled to work without payment. Boys were driven to dig ditches or small trenches for telephone wires under fire. Those who refused for religious reasons to work on Sunday were fined. The Germans had closed all schools during their occupation of the French towns. The destruction of property was carried out in the most thorough fashion and according to systematized plans. Captured orders on the subject directed the blowing up of houses, wells, and cellars except those held by rear-guard outposts. Farm implements were burned and destroyed. Orders were given to collect filth in the neighborhood of wells to contaminate the water. All the fruit trees with rare exception in the evacuated territory were girdled or otherwise killed. The use of cavalry by the French and British seemed to have taken the Germans by surprise and interfered with their plans. In one village they were forced to hurriedly depart without touching the supper which was laid out on the table. In other places the Allies found newly opened boxes of explosives with which the Germans had planned to destroy the villages before leaving. The famous castle and stone village of Coucy-le-Chateau on the road from Paris to Namur, and one of the show places of the Laon region, were reduced to ruins. The village and castle date back to the thirteenth century and were regarded by art critics as architectural gems of medieval France. The castle had been spared from destruction during the French Revolution, and millions had been expended since on its preservation. This splendid monument of feudal Europe is no more. The German retreat was continued more slowly on March 19, 1917, when all northern France was swept by fierce equinoctial gales, and rain squalls were frequent in the battle area. Despite weather conditions, which hampered military operations, the British troops made good progress, and on the 20th held the line of the Somme in strength from Peronne southward to Canizy. British patrols were active as far east as Mons-en-Chaussee, and in several sectors between Bapaume and Arras British cavalry were engaged in skirmishes with the enemy.
