Hey there kiddo! Have you ever watched movies or read books about knights and soldiers fighting in big battles? Well, in those battles, there was something called a shield wall.
A shield wall is when a group of soldiers stand together really close to each other and hold their shields up in front of their bodies to create a wall. The wall is used to protect the soldiers behind the shield wall from enemy attacks. It's like a big human fortress!
The soldiers in the front of the shield wall hold their shields straight out so they cover the soldiers next to them. The soldiers behind them hold their shields up a little higher so they cover the heads of the soldiers in front of them. It's like they're building a big shield pyramid!
The idea is that the soldiers behind the shield wall can safely shoot arrows, throw rocks or spears, or even pour hot oil on the enemy, without getting hurt themselves. The shield wall also helps the soldiers stay organized and work together as a team.
So there you have it! A shield wall is like a big human fortress that soldiers use to protect themselves from enemy attacks during a battle. It's a clever strategy that helps soldiers work together and keep each other safe.
