The famous "miracle of the Marne" came as much from French successes as from German failures. Especially since the fall of France in 1940, historians have sometimes viewed the French as the beneficiaries of German errors and have given the French little credit for their victory. The time has come to take another look at the reasons for the French success.

To begin, France's grand strategy provided the foundation for the "miracle of the Marne." Historians often overlook the fact that French strategy was an alliance strategy and that Russia, not Great Britain, was France's most important ally. From the time of the first agreement in 1891 with Russia, France sought to force Germany to "fight at the same time in the east and the west." At the staff talks held between 1900 and 1913, France and Russia confirmed Germany's defeat as the "first and principal objective" of the two allies and the defeat of Germany's allies as subordinate objectives. While the British added additional troops in the West and reduced Germany's numerical advantage, the French did not expect much from them and were not certain they would arrive in time to participate in the campaign. Having the Russians as allies, however, forced the Germans to spread their resources across two widely separated fronts. Though the initial battles on the Western and Eastern Front did not yield the results the French optimistically expected, the Germans did shift two corps to the Eastern Front on August 25 and thereby weakened the "hammer" in their drive into France. Given the slimness of the Marne victory, those two corps could have made the difference between victory and defeat on the Western Front.


Action at the Marne

More so than its grand strategy, France's campaign strategy suffered from several serious flaws. While historians have often compared Plan XVII to the Schlieffen Plan, French strategy in August 1914 was not Plan XVII, which was a concentration plan. In fact, French strategy was Joffre's own, and he intended to comply with the agreement hammered out in numerous staff talks with the Russians and launch an offensive. Reluctant to reveal his intentions to political leaders and convinced the Germans would drive through Belgium, Joffre kept his intentions about advancing into Belgium private and did not reveal his strategy until August 8, when he issued General Instructions No. 1. Aiming to destroy the enemy's forces, not occupy or regain territory, Joffre wanted to jab with his right and attempt a knockout blow with his left. On his right he launched a raid into Alsace on August 7 and a supporting attack by First and Second armies into Lorraine on August 14 (the day the Russians began their offensive); on his left he ordered Third and Fourth armies into Belgium toward Arlon and Neufchâteau on August 21. While the raid into Alsace and the offensive on the right attempted to fix the German left and draw enemy forces to the south, the main attack on the left aimed to strike the less dense, more vulnerable German center in eastern Belgium and unhinge the powerful enemy force driving through central Belgium.

Despite great hopes for success, the supporting attack into Alsace-Lorraine and the main attack into eastern Belgium encountered strong resistance and were thrown back by the Germans. Joffre had grossly misjudged the size of the enemy forces in eastern Belgium, and the spirited, gallant charges by his soldiers collapsed in the face of withering machine gun and artillery fire. His strategy thus was disastrous and provided no advantage to the French.

As France had prepared to fight within Joffre's strategy, however, it had organized and equipped its forces for the offense and emphasized maneuver more so than firepower. The result was not only the infamous offensive a outrance but also light, mobile tactical units with minimal logistical and artillery support. French corps, for example, had only 75-mm cannon and expected to use artillery only to support an attack, not to fire days of preparation prior to one. Designed to charge into Belgium, the lean corps could maneuver easily or be moved rapidly over long distances. Beginning on the morning of August 24, Joffre started shifting forces from his right to his left. The first unit alerted for movement to the left was VII Corps which had performed poorly in the first attack into Alsace, but which was now moved from Joffre's far right to his far left. Had French units been trained and organized to fight defensively, rather than offensively, or had they been provided much more robust logistical and artillery support, they may not have been as mobile or as responsive when Joffre cobbled together his surge to the west.


Action at the Marne

To move units from Joffre's fain right to his far left, transportation specialists relied on the national network of railways. That system was built in the mid-l800s and initially resembled spokes on a wheel radiating from the hub, Paris. Later in the nineteenth century the French improved their railways by connecting these spokes at various locations, thus enabling trains to run from eastern France to northern France without passing directly through Paris. Also important was Joffre's understanding of the French railway system and its effect on strategic mobility. The foundation of that understanding was established in September-October 1909 when he became Director of Rear Services for the French army. After joining the Superior Council of War in February 1910, he conducted a very thorough assessment of France's requirements for artillery and, as part of that assessment, took a careful look at the strategic and operational movement of large units. He also directed two "maneuvers," one in February 1911 and the other in June, in which French forces were moved by railway from one extreme wing to another. As he states in his memoirs, these exercises contained the essential elements of the "maneuver of the Marne." Prewar experiences thus enabled Joffre to think through and accomplish the shifting of forces from his far right to his far left in August and September 1914.

Another contributing factor to the French victory pertains to communications. The German First Army, for example, relied almost exclusively on wireless transmission but had only two transmitting stations, one of which was connected directly with Moltke's headquarters and the other indirectly through Second Army. Since Moltke's headquarters had only one receiver, it often took several hours for a message to arrive. Furthermore, inclement weather interrupted communications, as did jamming from the Eiffel Tower. Having to encode or decode messages added to the time required to send or receive a message. According to First Army's chief of staff, important messages required as much as twenty-four hours for delivery. The distance between Moltke's headquarters and those of his subordinates compounded German difficulties. Since Moltke had to command forces in East Prussia as well as in Belgium and France, he initially located his headquarters in Koblenz but moved it on August 30 to a girls' school in Luxembourg. When written orders were sent from Koblenz or Luxembourg to First or Second Army headquarters, they often arrived, as the First Army Commander explained, "after the most important events had already begun."

In contrast to these difficulties, Joffre remained in close contact with his subordinates. An advantage for the French came from their falling back on their lines of communications and their relying on the telephone. While Moltke issued no orders from September 5 to 9 and received no reports from his First and Second Army commanders from September 7 to 9, Joffre maintained contact with his army commanders via telephone (even though he preferred written messages). The French also gained very valuable information from intercepted wireless transmissions. For example, on August 30 and 31, the British pulled back from the fighting line and left a huge hole between Sixth and Fifth armies. The French hoped the Germans would not find the gap, but an intercepted German radio transmission warned them that an enemy corps was poised to cross the Oise River near Bailly and march east. Only the early warning from the radio intercept, as well as some extraordinary luck, enabled Fifth Army to escape its perilous situation.


Action at the Marne

The frequent meetings Joffre had with his subordinate commanders and Sir John French provided the French another advantage. These meetings enabled him to take careful measure of his subordinates, provide them key instructions, and ensure they followed his directions. More than anything else, these meetings enabled the French and British to pull back successfully and operate in a coordinated, effective fashion. The meeting on August 26 between Joffre, Sir John, and General Charles Lanrezac, for example, provided Joffre important insights into what was happening on his left. The meeting occurred while British II Corps was heavily engaged at Le Cateau and revealed bad feelings between Lanrezac and Sir John. The British commander insisted Fifth Army had not kept him informed about its withdrawals and had left the British isolated. While the meeting provided Joffre an opportunity to explain his new campaign strategy with Sir John, it also provided him the first hint of Sir John's intention to pull out of the battle. In another meeting on August 30 with the British commander, Joffre tried to convince the British marshal to return his troops to the battle line between the Fifth and Sixth armies and provide Sixth Army time to assemble completely. After Sir John adamantly refused to do anything for forty-eight hours, Joffre left the British headquarters extremely discouraged, convinced he could not launch a counterattack near Amiens around the German right wing and certain he would have to change his strategy. When he returned to his headquarters, he ordered Fifth Army to break contact and withdraw, and he focused his efforts on halting the enemy along a new line running between Compiègne, Soissons, and Reims, thirty to forty kilometers to the rear of the Amiens-Reims line. The meeting had discouraged him but it had provided him the information he needed to respond to the new situation.

Another key meeting occurred on September 5 when Joffre met with Sir John French and urged him to participate in the counteroffensive the following day. In an emotional presentation the French general-in-chief explained his strategy, provided a description of the coming battle, and emphasized that he was committing all his soldiers into the battle in order to achieve victory. British forces, Joffre insisted, would play a crucial role in the campaign, but if they chose not to participate, their absence would be "severely judged by history." Banging his fist on the table, Joffre concluded, "The honor of England is at stake, Marshal." Sir John's faced turned red, and after a short silence, he tried to say something in French but then told one of the officers near him, "Damn it, I can't explain. Tell him that all that men can do our fellows will do." Without such meetings, Joffre could not have coordinated the complex withdrawal of the Allies and remained in close touch with what was happening. To underline their importance, think for a moment about what may have happened had Joffre been as distant or detached as Moltke. Beyond a doubt, the withdrawal would not have been well coordinated. More importantly, had Sir John French had almost no contact with him (as did Kluck and von Bülow with Moltkè), there is little doubt he and his troops would have withdrawn past Paris and never re-entered the battle.


Action at the Marne

Telephonic communications affected other important aspects of the campaign. For example, Gallieni called Joffre on the evening of the 4th and demanded the counteroffensive occur on the 6th, not on the 7th. Basically, Gallieni argued that Maunoury's Sixth Army would move into position--as directed by Joffre--on the evening of the 4th and probably would make contact with the enemy on the afternoon of the 5th and alert them to the threat against their flank. Recognizing the validity of Gallieni's concerns, Joffre changed the date of attack to the morning of September 6. At 2200 hours on September 4, Joffre's staff published the order providing the details for the attack on the Germans' extreme right on the 6th. And the final important change had occurred because of a telephone call from Gallieni.

Personal contact between Joffre and his subordinate commanders also enabled him to intercede when they began to falter. On August 30, he visited Third Army's headquarters and found its commander, General Ruffey, "very nervous" and "bitter" about the performance of his subordinates. The meeting occurred after liaison officers had warned Joffre of problems in Third Army. Judging it "imprudent" to leave Rut fey in command, Joffre relieved him. Four days later he relieved General Lanrezac, commander of Fifth Army. The relief of Lanrezac was "intensely painful" to Joffre who had known him for years and had great esteem for his intellectual gifts, but he had lost confidence in the Fifth Army commander and had tired of Lanrezac's challenging his orders. Just prior to meeting Lanrezac and relieving him, Joffre had met with General Franchet d'Espèrey and asked him if he were capable of commanding an army. The general had responded simply, "As well as anyone else." Needless to say, Franchet d'Espèrey turned out to be one of France's finest commanders.


A More Animated Joffre Than Usually Depicted

Beyond a doubt most of credit for what came to be known as the "miracle of the Marne" belongs to Joffre. After the collapse of his attempted maneuver around the German flank at Amiens, he kept his forces under control and did not panic when the Germans moved around the flank and into the rear of Fifth Army. As French and British forces withdrew, he remained in constant contact with them and prepared a counteroffensive. Though he did not foresee the subsequent course of events and did not attempt to trap the Germans, he recognized the opportunity to strike the enemy forces in their flank when Kluck's First Army turned to the east of Paris. In reality, this opportunity resembled what he had tried to do with Sixth Army on the Amiens-Reims line. Additionally, as Sixth, British, and Fifth armies attacked the Germans' right flank, Joffre displayed strong judgment and a remarkable degree of composure in his calm response to near disasters on both flanks of Fourth army, the right of Ninth Army, the left of Third Army, and the front of Second Army. Perhaps his greatest achievement was that he did not permit these near disasters to divert resources from the crucial actions on his left. Though he initially sought an envelopment with Sixth Army's attack from Paris against the enemy flank, he reacted capably and appropriately when a gap opened between the German First and Second armies and provided him the opportunity to send forces deep into the enemy's position. Gallieni's role was important, but the key concepts and decisions belonged to Joffre. In comparison to Sir John French, Grand Duke Nikolai Nikolaevich, Helmuth von Moltke, and Baron Conrad von Hôtzendorff, Joffre clearly was the best of the major commanders in this phase of the war, and he amply deserved the outpouring of praise he received after the victory of the Marne.


The Marne and Marshal Joffre Commemorated in a Childrens Book

Joffre, however, does not deserve all the credit. Without the valiant effort that came from the French soldiers, no Miracle of the Marne" would have been possible. For the soldiers who did the marching and fighting, the cost of the victory was not small, for some 329,000 of them were killed or missing in August and September 1914, the largest loss during any comparable period in the war. According to General Lanrezac, his soldiers in Fifth Army withdrew 140 kilometers from August 30 to September 5. As they withdrew, discipline began to break down, and some soldiers deserted their units. A few began pillaging and terrifying civilians. The great majority of the French soldiers however maintained their discipline and their unit cohesion. Rumors of German atrocities--including shooting defenseless civilians, burning villages, and widespread raping and pillaging--strengthened the soldiers resolve to continue marching until the time was right for them to turn on the enemy. In the final analysis, their ability and willingness to stop withdrawing on September 5 or 6, do an about-face against enemy pressure, and resume the offensive was truly remarkable. Their grim determination to drive the German invaders from their nations s soil ultimately made the difference in the outcome of the "miracle of the Marne."
