Sync two animations on two different gameObjects

Hi,

I have a top down game, based on grid. Similar to chess. My problem is syncing animations on two different game objects. When two figures meets on neighbouring fields they should play animations of attack and hit until one of them will be killed. For now I using coroutine to handle the fight. In Update I find units, sets they state to busy and start fight coroutine.

     IEnumerator Fight(Cell attackerCell, Cell opponentCell, IFightable attacker, IFightable opponent)
     {
         attackerCell.Unit ().busy = true;
         opponentCell.Unit ().busy = true;
 
         int attackerPower = attacker.attack - opponent.defense;
 
         if (attackerPower > 0) {
             opponent.health -= attackerPower;
             attacker.animator.SetTrigger("Attack");
             yield return new WaitForSeconds(attacker.animator.GetCurrentAnimatorStateInfo(0).length);
             opponent.animator.SetTrigger("Hit");
             yield return new WaitForSeconds(opponent.animator.GetCurrentAnimatorStateInfo(0).length);
 
             if (opponent.health <= 0) {
                 attackerCell.Unit ().busy = false;
                 Grid.self.ClearCell(opponentCell);
                 yield break;
             }
         }
 
         yield return new WaitForSeconds(1f);
 
         int opponentPower = opponent.attack - attacker.defense;
         
         if (opponentPower > 0) {
             attacker.health -= opponentPower;
             opponent.animator.SetTrigger("Attack");
             yield return new WaitForSeconds(opponent.animator.GetCurrentAnimatorStateInfo(0).length);
             attacker.animator.SetTrigger("Hit");
             yield return new WaitForSeconds(attacker.animator.GetCurrentAnimatorStateInfo(0).length);
 
             if (attacker.health <= 0) {
                 opponentCell.Unit ().busy = false;
                 Grid.self.ClearCell(attackerCell);
                 GameControll.self.money += 100;
                 yield break;
             }
         }
 
         yield return new WaitForSeconds(1f);
 
         attackerCell.Unit ().busy = false;
         opponentCell.Unit ().busy = false;
     }

Unfortunately it not work. When attack animation is in the middle, hit animation starts and after few iterations I can't say what is going on.

Anyone have any suggestions?

Thanks in advice
