The most important feature of the rest period was the reorganisation of Divisions on a ten-battalion basis,[6] of which a note has been given in the preceding chapter. In the 58th Division, as in the 56th, the 4th London Battalion was selected for continued existence, and at the end of January the 2/4th Battalion was strengthened by the transference from the disbanded 2/1st Londons of 10 officers and 221 other ranks. The officers who joined from the 2/1st Londons were Capt. W. D. Ramsey; Lieuts. W. C. Morton, G. J. L. Menges, W. B. Evans; 2/Lieuts. R. H. J. Mendl, A. Woodington, C. J. C. Wildman, W. H. Parslow, S. H. E. Crane and H. W. Durlacher. After the reorganisation the infantry of the Division comprised the following units:

Before the Division left the Amiens area the imminence of a German offensive was a matter of common knowledge to all ranks, and so impressed with the seriousness of the situation was the High Command, that on the 5th February a most inspiring message from General Gough was conveyed in a lecture by the Brigadier, to all officers, warrant officers and sergeants of the Brigade.

The state of affairs was indeed critical and a grave crisis in the War was approaching. Some slight account of the general conditions which had brought this about has already been attempted, and there is no occasion now to recapitulate the main factors of the situation in which the Allies found themselves. We must, however, point to one or two conditions especially attaching to the British front which had a pre-eminent influence on what followed.

The gradual and ever-increasing numerical preponderance of the Germans on the British front has been referred to; translated into numbers the position may be better appreciated. During the period from the 1st November 1917 to the 21st March 1918, the number of German divisions on the Western front rose steadily from 146 to 192, an increase of 46, against which the total number of British divisions in France was but 58, and these sadly depleted in numbers. The question of the falling off in the numbers of reinforcements sent to France at this period has become the subject of an embittered controversy to which we do not propose to offer any contribution. We are, however, concerned in pointing to the result, whatever the cause, of this growing numerical disparity, which was to confront G.H.Q. with a most anxious problem. The British front was now some 125 miles long, and a glance at any war map will show that the general trend of the front was in a north-westerly direction, i.e. near its northern extremity the line ran comparatively close to the sea. In other words, the space available for manœuvre in the event of a considerable break-through by enemy forces was dangerously small in the vital neighbourhood of the Channel Ports; and a successful German offensive in this region might have the effect of rolling up our forces against the sea. In the south the space between the lines and the sea was greater, but a large enemy success in the southern area also had serious possibilities as it might entail the complete isolation of the British Armies from the French.

These were very briefly the two alternative possibilities which G.H.Q. had to face, and the problem awaiting solution was how to provide with the inadequate force at its disposal for the efficient defence of its lines no matter where the blow might fall. The matter was further complicated. The French were equally nervous of a sudden blow against their weak spots in Champagne and at Rheims, which might lay open the German road to Paris, and this fear rendered it impossible for them to place at the disposal of British G.H.Q. sufficient forces to make up the very grave inequality of strength which existed on the British front. The grouping of forces was, moreover, rendered more difficult by the fact that, so great were the available German reserves, it might well prove that the first enemy blow, although serious and energetic, might in reality not be the main effort. This doubt would inevitably, whatever the Allies' dispositions might be, have the effect of sterilising the British and French reserves for some days until it was quite certain that the first blow was not a feint, to be succeeded later by a still greater effort elsewhere.

Such was the problem, and surely never has a military commander been faced by a more difficult situation; for on the wisdom of G.H.Q.'s dispositions would probably rest the fortunes of the whole British Empire.

Before stating the solution adopted by G.H.Q. in especial relation to the doings of the 2/4th Battalion, we may perhaps be pardoned for glancing at one or two aspects of Ludendorff's problem which, as is now known from his own book, was by no means free from difficulty.

The vital necessity of a stern British defence of the Channel Ports was appreciated by Ludendorff as fully as by the British G.H.Q., and he was therefore alive to the possibility—knowing the British inferiority in numbers—that the overwhelming importance of the north might lead to a concentration of British divisions in the north at the expense of the southern area. But could he be certain that this course would be adopted? He might, after staking his all in the south, find that British G.H.Q. had outwitted him and anticipated his intention to attack at St Quentin. It was clearly essential that, to achieve the sweeping victory which alone could save Germany, Ludendorff must endeavour to encompass the temporary sterilisation of the Allied reserves which has been alluded to. To ensure this his plans must be shrouded in secrecy till the last moment; and the organisation of so vast an attack as was ultimately launched without disclosing its location to a vigilant enemy must have caused Ludendorff acute anxiety. That it was in fact accomplished can only beget admiration on our side for a most skilful opponent. And failure to Ludendorff, moreover, was fraught with consequences quite as awful from his point of view as his success would be to the British. Austria had gained a temporary respite in its victory over the Italians, but its army was becoming disintegrated and lacking in supplies; and no one realised more keenly than Ludendorff that the Dual Monarchy itself could not outlive a collapse of its army. In Germany the revolutionary ideas from Russia were beginning to have a weakening effect on the loyalty and steadfastness of an increasing section of the population; hunger was becoming intensified, for the comparative failure of the U-boat campaign resulted in an ever-tightening Allied blockade. And ever in front of Ludendorff loomed the spectre of gigantic American forces on their way to France, which the U-boats were powerless to stop. How many Americans had landed? How soon could they be thrown into the battle line to turn the scale against the Central Powers? These were questions to which Ludendorff must earnestly have sought an answer, and which must have brought home to him the realisation that this gigantic bid for victory he was preparing would for good or evil be the last effort which Germany could make.
