About 100 years ago during the Mexican Revolution, El Paso buildings and El Pasoans were hit by shots fired from Juárez. The brick walls on the south side of the old laundry building on South Santa Fe Street still have the pockmarks of revolutionary bullets.
In 1919, things got so bad that 3,600 U.S. troops rolled into Juárez to stop the fighting and help protect U.S. lives after three soldiers were hit by stray bullets, according to El Paso Times archives.
