Github, my branch is behind master but it is correct. How do I overwrite master with the branch?

问题

These are the steps I did on my way to this question:

How to remove duplicated commits from filter-branch command on git?

My branch A which only has 300 commits is 900 commits behind master. However, the 900 commits that I removed on branch A are duplicates. How can I just make master have 300 commits like branch A?

See original question: How to remove duplicated commits from filter-branch command on git?

This didn't seem to be working:

git checkout master
git reset --hard correct_branch
git push -f origin master

So I did:

git checkout master
git reset --hard old_commit_id_from_master
git push -f origin master
