Today in 1863 the Battle of Gettysburg concluded with a crushing Southern defeat after Pickett's Charge failed spectacularly. The bloodiest battle of any war for Americans resulted in over 50,000 casualties.

Something related to the Doppler effect?

Head scratching John
Yup, but wavelength of light vs wavelength of sound. Things approaching are “blue shifted” - shorter wavelengths due to moving towards you. Things receding are “red shifted” for the opposite reason. Just like sound generating objects have a higher pitch as they approach and a lower pitch as they move away.
