Assemblages of German troops north of Ailette were dispersed with heavy losses by the concentrated fire from French batteries. German attacks east of the plateaus led to violent hand-to-hand conflicts in which the Germans fought with great courage, but were unable to make gains. Throughout the day the battle raged, the Germans hurling great masses of men against the French lines, and, thrown back with heavy losses, again and again renewed the attacks. On the Californie Plateau after repeated repulses they succeeded in gaining a foothold, but were only able to hold it for a short time, when the French threw them back in an assault that laid many a German low. Since the 10th of the month the British had done little but repel counterattacks, but they had won a little useful ground east of Monchy, close to the coast, and around Ypres and Lens theirs and the German batteries were busy day and night. From prisoners captured by the British it was learned that the Germans were suffering from the great wastage of men. Out of one division west of Lens it was stated that between seventy and eighty men had been buried every day for some weeks past. The British losses were also considerable, but their guns did more shooting, and the enemy's casualties were consequently much heavier. The British continued to hold the upper hand in air combats, few German machines being encountered. During July 23-24, 1917, British airmen dropped between four and five tons of bombs on enemy aerodromes, ammunition depots, and railway junctions with good results. North and east of Ypres the British made several raids during the 24th, capturing 114 prisoners, including two officers. On the French front General Petain, commander in chief of the French armies, found time while the battle was still raging to review the famous division whose four regiments had won the highest honors at Verdun, Nieuport, on the Somme, and in the Champagne. The troops which had been fighting for three years showed outwardly no sign of the terrible ordeals they had undergone, holding themselves proudly erect as they passed the saluting base amid the strains of military music and flying colors. General Petain, who believed in treating his men as if they were his own sons, commended their bravery and thanked them in the name of the Republic for the brilliant example they had set to the other soldiers of France.
