In 1917 Arthur Zimmerman sent a coded telegram to the Revolutionary Mexican Government that would change the shape of American and German history for the next fifty odd years. The telegrams contents would contain a proposal of an alliance with the German Empire, large financial support, and the promise that Mexico would be allowed to reconquer the territory in Texas, New Mexico, and Arizona. Additionally the telegram stated that the German war machine would once again resume their unrestricted submarine warfare. This telegram was decoded by the British and instantly sent to the United States government, who until this point had remained aloof to the war. It was this and other incidents which sparked America's involvement in World War One. The Mexican government publicly declared that they denounced the telegrams contents, and announced that the nation would remain neutral allowing the Germans to maintain their companies there but also shipping oil to the British. But did they privately approve of the document?
According to sources, the president put together a committee that had the goal of deciding whether or not war with America was something that could take place. They however came to the conclusion that this was just not something that could be done by the war torn Mexican state as of now. They concluded that they could not foresee a situation where the army of Mexico beats the United States Army alone. But with the mobilization of Germany and the incredible conscription that gripped the country in the last years before the war and the years in it, what if the Mexican Government received German help in the invasion of America?
Point of Divergence
While the Mexican revolutionary government would publicly denounce the actions of Arthur Zimmerman, and remain neutral, they still hungered after the prized possessions that they had lost in their war with the United States. In the dead of night of the coast of Yucatan administrative district in Mexico, elements of the German First Army Corps would offload men and supplies. They would travel inland and construct a small army base in the Yucatan wilderness with the permission of the Mexican government. Of those who would be housed in this facility were the 244th infantry division, the 17th pioneer battalion, and numerous administrative and technical staff. Between the years of 1910-1914 nearly 150,000 Germans would migrate to the United States. Thirty thousand of these immigrants would be termed "Eisen Jagers" or iron hunters. On the pretense of hunting for iron deposits for German based company Thyssen AG, these thirty thousand German nationalists would make their way down to the hidden German Army base in the Yucatan wilderness. The base which was nicknamed "Kindergarten" was located to the southwest of Merida, the major city in the Yucatan province, its main goal was to train those immigrants who came to the base for an assault on the American southern border. The German government has no illusions that the single corps of men, without cavalry or artillery, would be able to occupy any sort of land in the United States. The force once fully trained was merely to encourage the Mexican government that they would have German support in their fight, and to tie down American troops so they would not reach the European Front.
Initially the Mexicans were not excited about the proposal. If the United States government found out that a German Army corps was training on Mexican soil there would be serious consequences. They, however, were convinced of its success upon meeting the commanding officer for the mission, Oberst Yannick Giechson. A hard man who you couldn't help but feel the energy of, the Mexican government took the word of the operations success. The entire operation detailed another few divisions landing into the port of Vera Cruz once the two divisions in Yucatan were ready. This however would be interrupted with the United States occupation of Vera Cruz in 1915, due to diplomatic tension with Revolution leader Victoriano. In anger the Mexican government urged Oberst Yannick Giechson to accelerate his plan, providing his newly trained and untested army with a full Mexican Army Corps under his command.
The occupation of Vera Cruz would force the Oberst to accelerate his plans. In late April a close time in which British Armed forces would be landing on Gallipoli, both the 244th Infantry division and the newly trained companion division the 244th Landwehr would assault the American occupation of Vera Cruz. With artillery support of the Mexican army, the American forces where taken by complete surprise, the port taken with little loss. The Oberst would move his forces to the American border. There he would engage the few army units and national guard units that the United States could raise up. However the American units where under prepared and under equipped losing ground heavily to the operations army. The German-Mexican force would make progress, taking the cities of Lardeo, Corpus Christi, Brownsville, and San Antonio. This however was as far as the operation would go. The American government quickly responding to the attack on their own soil, mobilizing their extensive manpower. The Operation would ultimately fail in in purpose after one year of extensive fighting. The two German units would retreat to their base in the Yucatan, while the Mexican army is destroyed all together. This resulted in the American annexation of Baja California, under the largely American dictated Treaty of Belize. However the United States had lost 114,229 men, and was not willing to risk the life's of more men in the War in Europe. They made white peace with Germany on the condition that no territory would be annexed in Europe, signing the Rio Grande Accords.
Without the Americans support in the European front the war would last until 1921. The French army would eventually collapse under the weight of German attrition and the French's failed assaults, leaving German units to flood into Paris and the Picard region of France. The British army would hold but now would be surrounded in the Swamps of Flanders. Surrounded except on the ocean in which they would retreat to Great Britain and settle in for a defense. The British government recognized that they could not take back the land without American assistance. Prime Minister of Britain, H. H. Asquith of the Liberal Party reached out to the German government and made white peace. Against the United States' wishes Germany annexed the territories of Champagne, Picardy and Nord de Pas Calais, violating the Rio Grande Accords.
Oberst Yannick would allow the men who wanted to return to their homes in German go, and they were received with much accolades. Oberst Yannick would stay however with a vast majority of the troops and found the Mexican Foreign Legion, Yannick taking the role of General in the new revolutionary government. The legion would attract many Germans who disagreed with the German government and we'll as large amounts of foreign soldiers fleeing their country in the aftermath of World War One. Under Yannick the Foreign Legion would become the elite soldiers of the Mexican Army. Two years after the Treaty of Belize the legion would spearhead an assault into Guatemala, annexing it for the Mexican government.
