The Battle of Sarrish was a battle that took place during the Clone Wars in 20 BBY when the Republic fought against the Separatists to capture the planet. While the Republic achieved its share of victories in the campaign, the battle was ultimately won by the Confederacy, which caused heavy clone trooper casualties, making it one of the Republic's most devastating losses. The battle also caused Clone Commando, Captain Gregor to lose his memory, and he eventually went missing in action.
