Four Canadian divisions under Sir Arthur Currie, on the right of an eleven-mile front, four Australian divisions under Sir John Monash in the centre, with the Third British Corps under General Butler on the left, led the splendid advance.

The Field Marshal in his dispatch speaks of the "brilliant and predominating part" played by the two Dominion Corps--the "skill and determination of the infantry," the "fine performance" of the cavalry.
By this victory the British Army recovered the initiative it had temporarily lost.

All was changed.

And even more striking than the actual gains in ground, prisoners, and guns, was the effect upon the _morale_ of both German and British troops.

The Germans could hardly believe their defeat; the British exultantly knew that their hour had come.
In _the Battle of Bapaume_ (August 21st-September 1st) the Third and Fourth British Armies, twenty-three divisions against thirty-five German divisions, drove the enemy from one side of the old Somme battle-field to the other, recovered all the ground lost in the spring, and took 34,000 prisoners and 270 guns.
