How to revert a range of commits when it contains some merge commits?

Question

I am trying to revert a range of commits where some commits are merge commits. I need the branch in exact copy before these range of "bad" commits (for example, last good commit is "A")

git revert B1^..B10

If some are merge commits, it will return error something like "...not allowed due to a merge but no -m option was given".

If I provide the option -m 1, it will revert but I am not getting the correct revision of code exactly the same if I checkout commit ID "A".

Note, I do want to keep history so using the reset command is not an option.

git commit

This looks like a winner. Thanks for the tip on `read-tree`. – eftshift0 Sep 17 '20 at 17:58

If you want to undo the last commit totally from git history, as well as the changes file changes, if you have NOT pushed:

git reset HEAD~1

If you have pushed

git reset HEAD

I did consider that but I want to keep history. – alltej Sep 17 '20 at 16:51
I think you should be able to use git reset --soft HEAD~1 to keep the history – Martins Sep 17 '20 at 16:53
