The nations at war had already soldiered on for more than four years, and the war would end in another few months, but Honduras President Francisco Bertrand awakened from a siesta and jumped into the fray by declaring war on Germany, taking the dubious honor of becoming the last nation in the world to declare war as part of World War I.
One can imagine the reaction in the German War Room when word arrived that Honduras had gone to the other side. The German command couldn’t have been too surprised since Britain, Serbia, Montenegro, Japan, Italy, Australia, Canada, India, New Zealand, United States, Panama, Greece, Guatemala, Nicaragua and Haiti had all declared war on Germany. And for its part, Germany had declared war against France, Russia, Belgium, and Portugal. (Practically everybody declared war on Bulgaria and the Ottoman Empire.) But Honduras!
The Honduran president was all set to commit troops to the worldwide effort before realizing that Germany was halfway around the world and had no rum. And the war declaration was really more a matter of sucking up to the United States by showing sympathy for its position than any actual hostility toward Germany. In fact, there were a large number of Germans living in Honduras, and they were not pleased. A year later they retaliated by supporting Bertrand’s political enemies in overthrowing him.
