Unlike Hermione, Harry and Ron clearly understood that Gilderoy Lockhart was a useless blowhard who didn't know anything and had no useful skills (especially after coming to his office to tell him about the Basilisk and finding out he had no intentions of going to the Chamber and intended to run away; and didn't do any of the stuff in his books).

“What d’you want me to do?” said Lockhart weakly. “I don’t know where the Chamber of Secrets is. There’s nothing I can do.”
“You’re in luck,” said Harry, forcing Lockhart to his feet at wandpoint. “We think we know where it is. And what’s inside it. Let’s go.”
They marched Lockhart out of his office and down the nearest stairs, along the dark corridor where the messages shone on the wall, to the door of Moaning Myrtle’s bathroom.

So, why did they bother taking him with them to the Chamber of Secrets, instead of just stunning or petrifying him and leaving him around, either in his office or Myrtle's bathroom?

Interestingly, Lockhart himself asked that, but Harry didn't dignify him with an answer:

“Boys,” he said, his voice feeble. “Boys, what good will it do?”
Harry jabbed him in the back with his wand. Lockhart slid his legs into the pipe. “I really don’t think —” he started to say, but Ron gave him a push, and he slid out of sight.
Harry followed quickly. He lowered himself slowly into the pipe, then let go.

    I can only suspect that they felt they had no good way to otherwise subdue him / constrain him and didn't have time to go find another professor (also - what professor would take their word over another professor - even one as cagey as Lockhart?)

I can think of two good reasons

He was too dangerous to be left alone

Harry and Ron initially went to Gilderoy Lockhart to get his help. Upon Lockhart's confession that he was, in fact, completely useless, the professor attempted to erase their memories.

“Awfully sorry, boys, but I’ll have to put a Memory Charm on you now. Can’t have you blabbing my secrets all over the place. I’d never sell another book —” Harry reached his wand just in time. Lockhart had barely raised his, when Harry bellowed, “Expelliarmus!Harry Potter and the COS, ch. 16

Harry and Ron then felt forced to disarm him, essentially making him a foe and their prisoner. They couldn't just leave him in the room alone at this point; they were forced to bring him along to prevent themselves from getting attacked again.

Meat shield

Force him to "kick the door in" and take the brunt of whatever nasty thing they'd be facing.

They marched Lockhart out of his office and down the nearest stairs, along the dark corridor where the messages shone on the wall, to the door of Moaning Myrtle’s bathroom. They sent Lockhart in first. Harry was pleased to see that he was shaking.


“Well, you hardly seem to need me,” said Lockhart, with a shadow of his old smile. “I’ll just —” He put his hand on the door knob, but Ron and Harry both pointed their wands at him. “You can go first,” Ron snarled

    But they knew there's a handy spell called Petrificus Totalus, just for those occasions. Or just Wingardium-Leviosa a thick book on his head. Commented May 1, 2017 at 17:43

    @Gallifreyan Yeah, but short of killing him they probably figured any other spell would eventually wear off and make him a threat again.

    But they had his wand, and I'd reason that a coward like him won't follow me to the lair of a friggin' basilisk. Commented May 1, 2017 at 17:55

    What about the fact that it was revenge? Harry hated Gilderoy for his cowardice, something Harry doesn't understand and didn't particularly care if he died. They probably wanted him to. Commented May 1, 2017 at 21:42

    Certainly forcing him to face the kind of dramatic danger he falsely boasted of besting regularly would be quite appealing to Harry and Ron as "poetic justice".

A couple of reasons come to mind.

  1. He is an adult, and however stupid and bad at magic he is, it might be nice to have some adult presence (other than Tom Riddle)

  2. He was told to do the job by Dumbledore. Ron and Harry, Gryffindors that they are, think he should do it.

  3. Maybe they think they're in trouble for Disarming and overpowering a teacher (like when they triple-Disarmed Snape in PoA).

  4. This is the key point, and I think the best. It was because they refused to let him get away. When they confronted him he was packing a trunk. He then confessed that none of his adventures were real and tried to modify Harry and Ron's memories; but they overpowered him. They won't let him get away until they can expose him as a scam, and why not let him go first into the Chamber? Here's a quote:

    “Well, you hardly seem to need me,” said Lockhart, with a shadow of his old smile. “I’ll just—”

    He put his hand on the door knob, but Ron and Harry both pointed their wands at him.

    “You can go first,” Ron snarled.

    They just don't want him to get away.

  5. Basilisk fodder?


Gilderoy is still the only adult wizard around, Harry and Ron are still 12-year-old boys; they need all the help they can get. At the time, they believe him to be a braggart and a bit useless. They probably believe his books to be exaggerations, but they don't think he is actually dangerous to them. They don't know that the events in his books are complete fabrications, or about his skill with memory charms

Harry and Ron don't really empathise with Gilderoy here. They believe Gilderoy to be "on their side". They don't understand his fundamental cowardice, or his potential for evil. They think that if they can bring him to the chamber then he will start bravely; he just needs some encouragement. They were surprised that he was planning to run, so they had believed him to be basically decent. When it becomes apparent that he wants to avoid the chamber they still want him with them, as he is the only fully trained adult wizard around. As I said, they fail to understand Gilderoy, and that nearly gets them killed.

    "Gilderoy is still the only adult wizard around" -> Was the entire Hogwarts staff conveniently unavailable? If so, I need to go read CoS again...

    @Kevin They were around, but IIRC they were sending the students home, so any other adult would have made the kids go to their dormitories and pack instead of exploring an underground cave full of vicious monster. Commented May 1, 2017 at 20:13
  • Complete fabrications? Aren't the events in his books rather true except for the protagonist actually having been someone else who is now memory-wiped?

    This is fundamentally incorrect, I'm afraid. They absolutely do know that the events in the books are fabrications. Lockhart is absolutely not "on their side". They don't believe him to be decent at all. They see him as a threat, and rightly so since he'd just tried to wipe their own memories. Commented May 22, 2017 at 14:11
  • I disagree - Lockhart had already admitted that he hadn't done anything he claimed to have done in his books and that he had just tracked down the people that actually did it and took credit for it. So no, technically the books aren't complete fabrications (at least in the sense that those events actually had occurred), but they were fully aware that he hadn't done any of them himself. He had also already admitted to modifying the memories of the people who had actually done the stuff he took credit for (so that they couldn't rat him out), so they knew about that aspect too.
