The Union used several important tricks to win big battles like Gettysburg:

1. Strong Defense:

   • The Union Army, led by General George Meade, chose high places to set up their positions.
   • They especially took advantage of places like Cemetery Hill and Little Round Top.
   • This helped them use their better cannons effectively.

2. Bigger Numbers:

   • About 93,921 Union soldiers faced around 71,699 Confederate soldiers.
   • This meant they had the advantage in numbers at key spots.

3. Good Teamwork:

   • The Union had a great train system to quickly move troops and supplies.
   • This allowed them to bring in backup when it was needed the most.

4. Smart Planning:

   • The Union used signals and scouting to know what the Confederates were planning.

All these strategies helped lead to a clear Union victory at Gettysburg. This battle was a major turning point in the Civil War.
