The primary objective of the Union cavalry at Gettysburg was to scout and delay Confederate forces.

Cavalry units, led by commanders such as John Buford, played a vital role in collecting intelligence on enemy movements and offering early alerts about Confederate advances. Their responsibilities included engaging in skirmishes to hinder the attacking forces, thereby buying precious time for Union infantry to set up defensive positions. This approach was essential, as it enabled the Union Army to ready itself for the upcoming battle, fortifying their defensive line and ultimately aiding in their victory.
