This will be the last update for 1917, since I've come to the conclusion that internal politics and labor unrest in France and Italy are best covered in future posts. This one is a bit shorter than most, since the essential lineaments of the military campaigns of 1917 have already been covered in several of the previous entries. At the very bottom is a comparison of the strength of the various armies compared to OTL; this is important to setting the stage for the battles of 1918.
At this point, we are starting to leave the merely historical and enter the present - or at least, what the individuals in this timeline feel to be of palpable importance to their own lives. Of course, to some extent this applies to the entirety of the war, but it is particularly true of its last few years. Consequently, I'm going to give up the device of the omnipresent, omniscient narrator for future entries; more posts will be framed as debates between historians rather than as mere neutral retellings of events. Ideology will lay a thicker and more lustrous sheen on how the vast struggles of 1918 are retold. In a sense, I think this better approximates the actual spirit of the era; it was a time when it was difficult to be fully apolitical. Civilians and soldiers alike feel the need to take a stand, and their perception of events are indelibly linked to the positions they stake out. It was impossible to live through these events as a mere observer; it stands to reason that it is impossible to understand and narrate them as mere neutral spectators.
Thank you again to everyone who has been reading and providing feedback on the timeline. This has been a lot of fun, and I'm excited to hear what people think about the events to come! I've added a new poll at the top of the timeline to gauge what readers are most interested in hearing about; if it leans in one particular direction, it will probably structure the way that I do future updates.
_________________________________________________________________________________________________________
1917 was the first year in which all of the great powers abandoned the hopes of winning the war in a decisive offensive campaign. Its principal battles occurred in peripheral theatres, with smaller numbers of troops and more limited goals. In the wake of the mammoth campaigns of Lille and Verdun, none of the principal combatants felt comfortable launching another grand attack in the west.
The British did win a number of victories in the winter. But they were incapable of winning the war alone, without the support of their exhausted allies. In truth, the decision to direct their reserves toward the Balkans rather than France was an indication that even the British believed that there could be no decisive, war-winning victory anymore. In 1917, the Entente and Central Powers targeted each other's allies, attempting to knock out the weaker members of the opposing coalition so that they could more easily concentrate their forces on the stronger ones.
Insofar as this was the strategy, none of the great powers were successful. Italy, Bulgaria, Romania, and Turkey all weathered assaults from superior armies. Some of these minor powers suffered worse than others, but all were able to remain in the war. Perhaps the most crucial moment of the year came in March, when an Austro-German force defeated in detail several Greek and Romanian armies outside of Sofia, breaking the siege of the city and ensuring that Bulgaria stayed in the fight.
Hindenburg and Ludendorff believed that the "eastern problem" of Romania had to be dealt with as soon as possible; they worried that more Romanian successes might prompt Russia to launch an offensive. In this, they likely overestimated the morale of the average Russian soldier, but it ended up dictating German war policy throughout the year regardless. Germany and Austria agreed to a set of offensives in May, one to retake eastern bulgaria and split the Entente forces in Constantinople from those in Romania, and another that would drive into the Po Valley and force an Italian surrender.
The Italian offensive achieved much more immediate success than the Bulgarian one. On May 7th, twin assaults began in the Trentino and Isonzo, the former toward Asiago and the latter toward Caparetto. For three days, dug-in Italian forces stubbornly resisted the assault in Isonzo until the mass use of poison gas drove them out of the trenches. The breakthrough in the north happened on the very first day, and Asiago was seized on the 11th. News of the seemingly unstoppable advance of the Austro-German mountaineers led to panic among the Italian soldiers in the Isonzo sector, who feared encirclement from the west. Udine fell by the 11th; by the 19th, Austrian forces had crossed the Piave, threatening the cities of Vicenza, Padua, and Venice. If they broke through here, the way would be open to the rest of the industrial Po Valley. Attempts to relieve the struggling Italians were foiled by the Irish revolt and a Central Powers offensive in Bulgaria.
The Balkan offensive ran into much more trouble than the Italian one. A week into the operation, there was no decisive breakout by the Central Powers. Well-equipped Romanian and British troops repeatedly threw back waves of German and Austrian soldiers advancing toward Pleven and Pazardzhik. It was only Romanian reluctance to divert its reserves to Bulgaria and British logistical trouble which eventually forced the Entente armies in Bulgaria to retreat.
This was not a rout. The retreat of Romanian-British forces was an orderly, fighting defense which inflicted crushing casualties on the invaders, particularly the Austrians, who were still not as well-equipped as their German counterparts. British forces in the region were able to hold onto the Ottoman city of Adrianople, while Romanian forces and a British army entrenched in Dobrudja. The remainder of the Romanian army successfully retreated behind the Danube river well before any attempt to bridge it could be attempted.
The Greek Army was missing from these operations, largely because Greece proper was in a low-level civil war. Peasant revolts in the mountainous north disrupted the army's supply chain and forced it to divert divisions to its rear. The ruling government of Venizelos was wracked by assassinations of cabinet ministers, labor stoppages, and food deficits. In the event of a concerted German-Austrian assault, the nation may very well have been forced to surrender, but neither the German nor the Austrian command considered it an important enough target.
In Italy, the valiant defense of several reserve mountaineer divisions outside of Vicenza bought enough time for France to transfer eight divisions to shore up Italian morale. By June 29th, the new front stabilized along an axis that ran in the west from Verdona through Vicenza, Padua, and Venice. The eastern portion of this defensive line was the most vulnerable to assault; the Italian government feared that another Central Powers offensive would force it to surrender Venice.
Although the Austrians hoped to dedicate the next phase of the offensive to Italy, Ludendorff believed it was still imperative to deal with Romania. In mid-august came a fresh offensive. In the west, a mixed Austro-German army invaded Transylvania, targeting heavily defended mountain passes held by elite Romanian troops. Further south, the Bulgarians assaulted Dobrudja, while Austrian troops stationed in Eastern Galicia and Western Ukraine marched into Moldova.
Falkenhayn's western armies found themselves thrown back time and again from the entrenched Romanian troops in Transylvania. In the northeast, an Austrian column led by Franz Confrad von hötzendorf made its way from Galicia into Moldovia, but was plagued by supply problems and guerilla activity. On the 21st, the German high command considered calling off the assault, but Conrad assured them that his army would soon break out of the forests of Moldavia into Wallachia, rendering the position of the Romanian mountaineers in Transylvania untenable.
By the 24th, Conrad had indeed made some progress in clearing Moldavia of its British-Romanian defenders; Jassy fell on the 22nd, and Kishenev two days later. But his efforts were soon rendered futile by a mutiny in the exhausted Bulgarian Army, many of whose soldiers had been fighting for over five years. Taking advantage of the chaos, two Romanian-British armies counterattacked, decimating a Bulgarian division, capturing several more, and then heading south towards Varna.
Shortly thereafter, the OHL called off the assault, relieved Falkenhayn of his command, and placed August von Mackensen in charge of halting the counteroffensive in the south. Meanwhile, the British Army in Dobrudja swung north to confront Conrad's force; Conrad, still confident of his position, ignored the instructions of the high command and continued south toward the town of Focsani. Romanian reserves released from Transylvania cut into his northern flank, while a British assault fixed his army in place. By the time he ordered his army to retreat, Romanian soldiers occupied much of the position to his rear. The battle of Foscani led to the loss of over 100,000 Austrian troops, the vast majority of them captured. Shortly after the defeat, Conrad von Hotzendorf was dismissed from the Austrian General Staff.
The failure of the Romanian offensive led the German general staff to shift its troops over to the defensive until a peace deal with Russia could be secured. It was widely believed that the Russian government would soon collapse, which would provide another opening to begin negotiations. Increasingly, hopes were placed in the upcoming campaign of submarine warfare, which high command believed could force the western powers into a harsh peace without requiring a costly offensive in France.
In reality, Britain was aware of the possibility of unrestricted submarine warfare for some time. Suspicions were first raised when German submarine activity declined precipitously in March and April despite the imposition of the blockade, prompting British naval officers to speculate about a future campaign of more concerted submarine warfare. British intelligence later revealed a build-up in submarine manufacturing in Germany. In July, a joint franco-british offensive was planned into Flanders to seize the Atlantic Ports from which German submarines operate, though it was a mostly hypothetical operation with no set date.
Then, in October, the campaign of unrestricted submarine warfare actually began. 165 submarines operating mainly from Flemish ports began to target merchant shipping in the English Channel and Atlantic. The insurrectionary activity in Saxony and Berlin convinced the British high command to push forward the planned Flanders offensive. It was hoped that low morale among the Germans would allow for a quick breakthrough. Massing in Ypres, two french armies and six British divisions prepared for the assault. By the time they were ready on October 23rd, the October Rising in Germany had been largely suppressed. But the entente had another trick up their sleeve: the first combat use of the new Franco-British landship, a hulking behemoth of mobile armor armed with the British 6-pounder naval gun and several machine guns. While its reliability and actual combat effectiveness left a great deal to be desired, the mass deployment of the vehicles had a crushing effect on German morale. Over the next month, the bloodiest battle since Verdun unfolded on the western front as the entente seized around half of the Flanders ports, creating massive logistical problems for German submarine operations.
Compared to OTL...
The German Army is around the same strength, having taken around 2-3% less casualties.
The Austro-Hungarian Army is considerably stronger, having suffered around 25% less casualties. It is also somewhat better equipped.
The Bulgarian Army is incomparably weaker: years of fighting have depleted its manpower reserves.
The Turkish Army is considerably weaker. It has taken around 25% more casualties, and is by this point much worse equipped than any other army.
The French Army is somewhat weaker, having taken around 10% more casualties; they are beginning to have trouble replenishing battlefield losses. It is slightly worse equipped; the French government is in a worse fiscal situation, meaning munitions production is starting to face some financial bottlenecks.
The British Army is considerably stronger, with more enlisted men, more artillery pieces and shells available, and around 15% less casualties taken.
The Russian Army is considerably weaker, having suffered around 25% more captured, injured, and killed soldiers compared to our timeline.
The Italian Army is somewhat weaker, having taken around 10% more casualties. It is around as well-equipped as IOTL.
The Romanian Army is considerably stronger. It is around 20% larger, and much better equipped than IOTL.
At this point, we are starting to leave the merely historical and enter the present - or at least, what the individuals in this timeline feel to be of palpable importance to their own lives. Of course, to some extent this applies to the entirety of the war, but it is particularly true of its last few years.
