It only waists time and leaves the ships venerable to attack.
The only advice other than 'fight hard' that I can give you is DO NOT ATTACK THE ROMULAN STARBASE. You have to protect some medical starships that are en-route to cure several planets of a deadly disease. The campaign mission 'The Shepard' is very difficult. Even thought you can play the Federation, Romulans, Klingon, and Borg you can only be the Federation in the campaign. You select your race, era and fleet size then go out to battle.
You can do this strategy-building in the Skirmish mode in the game. It is impossible to get past even the first mission in the campaign without developing a strategy against your enemy.
