Peter, even though he later denied Jesus, felt here that he should try to protect Him. In another gospel, John 18:19, Jesus issues a gentle rebuke saying "Put up your sword, the cup that my Father has given me shall I not drink it?" Then Jesus reaches out and touches the servants ear and heals him. This was the last recorded miracle of Jesus. Now here Jesus rebukes the people who took Him. In Luke 22:53 we read: "When I was daily with you in the temple, ye stretched forth no hands against me: but this is your hour, and the power of darkness."
It was at this point that the rest of Jesus' disciples forsook Him and fled just like Jesus said they would. There is the story of the young man following. The man laid hold of him and he fled naked. This is said to be the writer Mark but we don't have any proof. Imagine yourself in the position of the disciples with this young man. Would you follow through with following Jesus or turn back?
