How to revert multiple git commits?

Question

I have a git repository that looks like this:

A <- B <- C <- D <- HEAD

I want the head of the branch to point to A, i.e. I want B

Answer 1

I really wanted to avoid hard resets, this is what I came up with.

A -> B -> C -> D -> HEAD

To go back to A (which is 4 steps back):

git pull                  # Get latest changes
git reset --soft HEAD~4   # Set back 4 steps
git stash                 # Stash the reset
git pull                  # Go back to head
git stash pop             # Pop the reset 
git commit -m "Revert"    # Commit the changes
