[Ansteorra] Latin Help

[Suren-unegen (Majestic Fox)]

Greetings,
I am having a little problem trying to translate something in to Latin. 
The phrase I am trying to translate is “First to fight loyal to the end” 
and I am coming up with this “Primoris pugno fidelis ut terminu” Is the 
translation anywhere close to where I need to be?
