Epic. Infantry Combat First

Artillery and infantry unit X are attacking enemy infantry unit in combined attack. Enemy player plays Infantry Combat First card and forces attacking infantry unit X to retreat. Does this mean that the attacking artillery unit can no longer attack the enemy inf unit or any orher unit this turn?

correct

"If a defending unit plays a First Strike card against a combined arms attack and either eliminates the attacking infantry or cavalry unit or forces it to retreat, the artillery’s attack dice committed to the combined arms combat are lost because no attacker melee occurs."

Thanks for the reply. Even though the card has a different name to First Strike the result is the same as first strike, so I guess thats what makes the difference.
Cheers
