THE CAMPAIGN OF 1917
 DESPITE discouragement and disaster the strategy of the Allies remained in 1917 what it had been in the two years
previous. The Allied statesmen still believed that unless victory were won in France it would be worthless.
They must not merely beat the German army somewhere; they must drive it from France and Belgium; a
satisfactory peace could be signed only with the Germans across the Rhine. The trench line imposed upon the
assault extreme difficulties and sacrifices, but they saw no real alternative. They prepared themselves
therefore once more to deliver a simultaneous offensive on all fronts, on the theory that the previous logic
was good, but that the earlier preparations had not been sufficiently elaborate. More men, more cannon, more
ammunition, larger artillery, and better trained infantry must infallibly succeed. They proposed also to win
back the ground lost in Asia Minor, where a very small British force had been defeated by a considerably
larger Turkish army. The military positions were of no consequence to the issue of the war, but the British
made it a point of pride to recover the lost ground before the war should end.
The German plans were, as usual, based upon their suppositions as to the plans and preparations of the Allies
in France. Hindenburg still seemed in 1917 to cling to his original plan of holding the lines in the west,
while all German foes in the east were beaten and victory then made final. Though the Russian army had been
considered beaten in 1915, had been again demolished in 1916, its
 continued existence alone compelled the Germans to retain a strong force of men on the eastern front. They
therefore schemed in the winter of 1917 to remove Russia permanently from the conflict and to conquer her for
the present and for the future. They precipitated the Russian Revolution in March,
to put Russia definitely out of the war and to release the German armies on the east front. They would then
throw large forces against Italy in the fall of the year, at the season most favorable
 for the campaigning in the south, and treat her as they had treated Poland and Rumania. They could then end
the war in 1918.
ALLIED GAIN IN 1917 DUEL.
Meanwhile Von Tirpitz was to attempt to bring England to her knees by means of unrestricted submarine warfare.
For two years now the submarine had sunk British shipping where it could, but, despite their general lack of
humanity, the Germans had observed some of the rules and practices of the past. They now announced to the
world that from February 1, 1917, they would sink any and all ships that the submarines might meet. They
declared a danger zone around the British Isles and the French coast within which no ship, however neutral,
should be safe. They thus rescinded all the promises they had made to the United States and other nations of
warning to vessels in order to allow the crew and passengers to escape. The new order was "Sink without
trace": the ship must disappear—there must be no survivors to tell the tale of how she was lost. They
promised themselves that England and France would be put to such straits by this unrestricted warfare that the
factories would be unable to get the raw materials necessary to continue the war. Food would give out,
especially in England, and the British would be compelled to sue for peace.
Meantime while Russia was being successfully revolutionized, while the submarine was bringing Great Britain to
terms, the lines should be held in France with the least possible effort. They should maintain the defensive
as cheaply as possible. Hindenburg knew well that the British and French had made extraordinary preparations
throughout the fall and winter for an assault upon the German lines. Special railroads had been built all
along the front to make easy the movement of troops, of ammunition, and of food so that men could be massed
readily at any point, transferred elsewhere with rapidity, fed there, and supplied with ammunition.
 In February and March, therefore, to render all these preparations useless, Hindenburg withdrew the German
lines to the famous Hindenburg line, a new line of defense elaborately prepared, miles enough in the rear of
the old line to prevent any assault upon it by the British and French from the positions which they had
prepared so carefully during the winter. Moreover, the Germans destroyed every living thing, every building,
every tree, every possible shelter in the entire zone, which they thus abandoned; it was laid waste with a
thoroughness which only Germans can attain. The Allies must therefore attack them over a waste ground where
 would impede their progress to the maximum and where there would be nothing to aid them.
WEST FRONT IN 1917 AND TOTAL GAIN IN THAT YEAR.
The results were not exactly what the Germans had anticipated. The United States promptly entered the war on
April 6, 1917, and undertook with equal promptitude an extent of preparations which paralyzed the German
statesmen and generals. Conscription was voted almost immediately and an army of millions was put at once into
training. The United States government took over factories and railroads and began to build ships to transport
the new troops to France. Indeed, we began to build from the bottom an army of five millions of men, with
everything necessary to place them on the fighting line in France and keep them there indefinitely. The
example of the United States was followed by declarations of war from a crowd of hitherto neutral states in
South America and in Asia.
In a measure the new submarine menace was met by the seizure of German ships interned in American and neutral
harbors. They were promptly repaired, despite the fact that the Germans had intended to injure them so that
they could not be put into service for some years. In June, Greece joined the Allies, and the obstacle to an
assault upon the Austrian rear, which had bothered the Allies for three years, was removed.
In April the British delivered a great assault on the German lines around the city of Arras, to the north of
the new Hindenburg line in a position not affected by the German retirement. Although some territory was won,
the battle failed to break through the German trenches, and in July the British began a determined effort,
which was continued until December, to break through the German lines along the coast so as to reach the
submarine base at Ostend and Zeebrugge. Not only did they feel that if they could capture the coast they might
lessen the power of the
sub-  marine, which was already committing great inroads upon the world's shipping, but they might also turn the
German right and compel the withdrawal of the whole line over a considerable area of territory. But the
attempt failed. In the center an attack was launched on November 20, at Cambrai, known as the battle of the
tanks, which did gain a larger amount of territory than the Allies had up to that time won; but some of it was
lost again and in general the success failed to produce any effect upon the fundamental strength of the German
Meanwhile, the Italians had begun on the Isonzo in May a great assault against the Austrian army, intrenched
around Trieste. The object was twofold; partly to put pressure upon the Germans on two fronts at the same
time, and partly to win the Austrian territory occupied by people of Italian blood, which the Italians were
determined to add to Italy when the war should end. They felt that there was small chance of its cession to
Italy unless they should capture it during the war. They therefore made this determined attempt throughout the
summer to capture Trieste. In October, the Germans and the Austrians delivered a well-timed and well-planned
blow against the Italian army along the Isonzo. They broke the left of the Italian army before Trieste and won
through the mountains into the valley below.
THE SHADED AREA SHOWS ITALIA IRREDENTA.
The entire Italian position was at once flanked and the great bulk of the army in great danger of being cut
off and captured. To escape, it was necessary for the army almost to run; to abandon its artillery and
baggage; and to make its way back at breakneck speed to some new front. Finally, in November, after a
magnificent retreat, a new front was established on the Piave. British and French aid had been promised and
had arrived. The French and British had marched on foot from France, had crossed the Alps, and joined the
Italians. A furious attack was delivered by the
 Austrians in November and December, but the line on the Piave was successfully held.
Yet the net result of the year 1917 was extremely discouraging for the Allies. Russia was unalterably out of
the war; all possible help from her army had evaporated. Italy was in the gravest danger thinkable. The
submarine had been successful in sinking an amount of shipping which the Allies had not believed possible
although it was far less than the Germans had thought probable. It had not prevented the supply of the British
and French armies in France nor interfered for a day or an hour with the stream of ammunition, but, if the
loss should continue at that rate, there was no knowing when the submarine would make itself felt on the
battle line. England was building ships at furious speed; so was the United States; but the submarine was
sinking them immensely faster than they could be built.
Meanwhile the Allies had failed to gain anything of moment in France. They had supposed that a simultaneous
offensive on more than one front would expose the Germans and Austrians to certain defeat on some point. But
instead the Germans had successfully held the lines in France and had won victory after victory elsewhere. The
outlook was black indeed, for, although the United States had entered the war and had begun preparations of
extraordinary magnitude, the American army could not in the nature of things take the field in great force for
some months to come and perhaps for a year or more. The year 1918 every one foresaw would be the critical
period of the war.
