How to rebase an old commit on a deleted branch?

I have a quite strange git request. Here's a portion of my git history:

           -----2----- master
               / \
              /   3--- new dev
           --1  old dev

I would like to connect 3 to 1 like this:

    -----2----- master 
        / 
    ---1---3--- dev

The old dev and the new branch are now the same branch dev.

Is there a way to achieve this ?

Thanks to those who will answer.

Edit: The rest of my repo looks like this:

-2------5----7--- master 
  \    /    /
   3--4----6----- dev

So when I do as chepner said, I end up with this:

 -----2------5----7--------- master
       \    /    /
 ---1---3--4----6----------- dev
            \
             3'-------4'--5'--6' newdev

I want the newdev branch to have the same history of my dev branch with history changes made by the command of chepner.

I hope it's clear enough this time.

Branches in Git are simply "labels" and the active label moves with each new commit on this branch. That the old_dev branch was deleted is irrelevant here, the commit was merged and is thus part of the master branch's history.

The solution to your request is quite trivial:

git rebase --onto 1 2 new_dev

It will take all commits from 2..new_dev (excludes 2, includes 3) and place them onto commit 1.
