Under attack and dispatch

When you are under attack, but the attack has not started yet, can you dispatch troops to the attack point?

I had someone initiate an attack on my fort. I was located closer to the fort than the attacker (I was right next to it). With 30 seconds remaining prior to the arrival of the attack, I dispatched cavalry to the fort. When the battle began, I went to command and was surprised to find that I had no troops. When I went to look under Actions, I saw the troops still in dispatch with over 8 minutes to arrival (going one square). I wasn't sure if this was just how the game worked, that you can't dispatch troops to a location coming under attack, or if this was a glitch in the game?

Thoughts?

Hello,

You can dispatch to an attack point but in order for it to work your troops must arrive before the attack begins. It sounds like you waited until the last second and your troops did not make it in time. If they do not make it in time, they essentially act as a second attack and "stack" on the attack that is in progress (this delaying them 10 minutes). This is why your troops were 8 minutes back
