On April 19, 1880, the Austro-Central American colonial army pursued "ruthless bandits" and chased them into the Panama area.
Because of the fog, a misunderstanding occurred with the Colombian garrison, leading to an armed conflict that caused thousands of casualties.
Local residents could testify that a heavy fog indeed descended over the Panama area on April 19. Before the troops entered the Panama area, the colonial government had communicated with the local government, deciding to join forces in eradicating the nefarious "ruthless bandits."
Unfortunately, someone within the Colombian Government colluded with the "ruthless bandits," leaking the information. The bandits severed local telegraph communications and ambushed messengers en route.
