The Lachish Relief is a picture that was made a long, long time ago on the side of a big rock. It was made by some people who lived in a place called Ancient Egypt.
The picture shows lots of soldiers who are fighting in a big battle. Some of the soldiers are riding horses and others are walking. There are also lots of weapons, like bows and arrows, spears and shields.
The people who made the picture wanted to remember a important thing that happened a long time ago when the soldiers of Ancient Egypt won a big battle against people who lived in a different place called Judah. The battle was for a place called Lachish where the Judah people lived.
The Lachish Relief is special because it's one of the oldest and most famous pictures of a battle that has ever been made in the whole world. Lots of people go to visit it now because it's like a really old history book!
