What is wrong with this melee system?

Hello, guys! I am following some tutorials on Unity and I can't seem to figure out what might be the problem with this melee system.

I have a player and an enemy.

Player script: #pragma strict

     var Damage : int = 50;
     var Distance : float;
     var MaxDistance : float = 1.5;
     var TheMace : Transform;
     
     function Update ()
 { 
     if(Input.GetButtonDown("Fire1"))
     {
     TheMace.animation.Play("Attack");
         var hit : RaycastHit;
          if (Physics.Raycast(transform.position, transform.TransformDirection(Vector3.forward), hit))
         
         {
             Distance = hit.distance;
             if(Distance < MaxDistance)
             {
             hit.transform.SendMessage("Apply Damage", Damage, SendMessageOptions.DontRequireReceiver);
             
             }
         }
     }
    
   
     
 }

Enemy script: #pragma strict

    var Health = 100;
    
    
 function ApplyDamage (Damage : int)
 {
 Health -= Damage;
 }
 function Update ()
 {
     if (Health <=0)
     {
     Dead();
     }
 }
 function Dead ()
 {
 Destroy (gameObject);
 }
 

The enemy doesn't die, what can I do?
