Forrest was a master at psychological warfare - this is how he beat them. He used those tactics to give the impression his force was much larger than it was. He managed to outflank Sturgis both right and left - even though his troops were one thin line. He also sent Morton's artillery down the road extremely close to the Union lines - unsupported. The artillery barrage was solid and fierce, which is what Forrest wanted, and the enemy was certain there were more troops to support this. And we got one of Forrest's most famous sayings at this point. He patted Morton on the shoulder and said, "You got 'em skeered, John. Keep the skeer on 'em!" He was right - Sturgis couldn't get off the field fast enough. Forrest ordered one of his dogged pursuits which only ended when he himself fell off his horse with exhaustion - Sturgis was still running! Grierson was a division commander at this point - later, when he was promoted to higher command, he did well against Forrest. Unfortunately for Sherman, Sturgis was in command and he was, quite frankly, never the same again.
