title: Lost all commits when forced push in github
body: <p>Recently I created a PR in a forked repo and added few commits. Later I accidentally deleted the branch from <code>git bash</code>(<code>branch</code> was present in my forked repo). So I recreated a branch with the same name and in that, I tried to push new commits. But it rejected the commits at first, so I forced pushed the commit, but this removed all the previous commits from the PR in <code>github</code>.</p>
  
  <p>I don't know what happened here. Also is it possible to get back all the lost commits?</p>
