Details of the first advance from St. Quentin to Noyon illustrate the new method pursued in this offensive in the particular way in which one large unit passes through another in order to carry the movement forward as rapidly as possible. Another feature is its readiness to change the direction of march when great difficulty is found by the Germans or a marked weakness on the allied side invites such a change. Of the divisions named above, six disappeared from that front in the course of the concentration toward Noyon. They had been diverted westward when it was recognized that the Oise could not be forced, and Amiens became the chief objective. It is certain that General von Hutier's plans were based upon his experience in the capture of Riga. * * * Western resistance, whether French or British, is a very different thing from that which the Russians put up at Riga. Enormous as are the forces the enemy put into this blow, though for the last week they outnumbered and generally overwhelmed those hurried up to meet them, they had to pay terribly for their success. German war doctrine recognizes this as inevitable in what is intended for a decisive operation against great antagonists. Against soldiers less experienced, disciplined, and inspired than those of the western Allies Hindenburg would have succeeded. The adaptability of direction of attack which I have indicated is remarkable, but the same adaptability in the attack upon Verdun, where the right and left banks of the Meuse were alternately tried, gave no result. This time the main direction has been thrice changed. It began with the wings at St. Quentin and Croisilles; it then moved to the right centre from Bapaume to Albert; finally it is concentrated on the left centre on both sides of Montdidier. Because of its methods and speed the battle thus far has been mainly one of artillery. German cavalry has been met in small numbers, but it has not taken a brilliant part. The enemy's aviation service has been notably inferior to that of the Allies. Only light guns with a few four-inch pieces have been able to keep up with the advance, and trench mortars do not seem to have been brought up quickly. On the other hand, groups of allied machine gunners and machine riflemen, taking advantage of the depressions of the ground, have everywhere taken heavy toll of their adversaries. By the time they can transport their heavier guns the Allies will have their former superiority ready to answer them. FAILED TO BREAK THROUGH March 26.--A full third of the German forces on the western front have been engaged on one-eighth of its extent. It is not impossible that a secondary offensive may be declared, but it may be taken that we now know the worst, and that the utmost possible strength has been put into the first blow.
