2 things: 1) Yes, you are right as everyone has their own tactic and no one can tell you you're wrong.
2) If you want to make them run back, you just have to keep on trying, eventually with practice you'll make perfect. I personally like keeping my archers behind my infantry because I feel safer that way, but I've seen people rip an entire army to shreds because they made their archers soften the enemy lines and afterwards running behind their infantry, do what you like and what feels best for you.
