CAMBRAI.—

Then, in December, comes our surprise attack at Cambrai: it is effective, for PRISONERS nearly approaches CASUALTIES. LINE increases, owing to the salient formed by the British advance. Then, the German counter-attack, with CASUALTIES high, PRISONERS few, and LINE decreasing. The Germans have reduced the salient made by our attack.

ITALY'S PLIGHT.—

But meanwhile, the enemy has struck at Italy, and Italy, reeling under his blows, is clamant for aid. Division after Division hurries off! STRENGTH falls, never again to ascend. The handicap is permanent.

1918.—

With STRENGTH almost at its lowest since 1916, after a year of ceaseless fighting and heavy casualties, with five Divisions diverted to Italy, miles of FRONT have to be taken over from the French. Line held reaches its maximum, 130 miles. Fighting strength has fallen by mid-March—when Divisions have been reorganised from 12 to 9 battalions, owing to the dwindling of reinforcements—to 580,000.

THE GERMAN THRUSTS.—

The Chart has shown when we might attack. Now it gives the warning to expect attack. Now, if ever, is Germany's moment, and her first great blow falls on March 21st—the thrust at Amiens. CASUALTIES soar to a height never before approached. The red line predominates—STRENGTH falls and falls. Divisions are summoned from Italy and Egypt. The second German blow falls on the Lys. CASUALTIES are again immense, though not so high as in the first attack. STRENGTH falls again. The Lys salient increases the line held, but by the end of May the Line is firm throughout. Some few thousand Americans for a time reinforce the war-weary British Divisions; but the Portuguese cease to be reckoned in our fighting strength, though still in France. Reorganisation follows. STRENGTH is built up a little, though CASUALTIES are still heavy. The IXth Corps is fighting fiercely on the French Front to stem the Paris Thrust in May, and four British Divisions help in Foch's July counter-thrust. Guns, despite our losses to the enemy, have again increased. Guns are now more easily replaced than men.

THE FINAL PHASES.—

Then the final phase. With decreased FIGHTING STRENGTH but with abundant GUNS (and, be it added, Tanks), we strike our first great blow in the Battle of Amiens on August 8th. STRENGTH falls abruptly, CASUALTIES are many, but high above the casualty line soars—for the first time—the line of PRISONERS. The toll taken of the German armies increases, as Bapaume and the Scarpe swiftly follow Amiens.
