Beginning to prepare for an epic adventure I will run this coming summer (I plan early lol).

Beginning to prepare for an epic adventure I will run this coming summer (I plan early lol). I want my PCs to attack a small goblin camp, with 7 regular thugs, 5 soldiers, 3 archers, a magician, and a chieftain (all goblins). This will be a fight for PCs at level 1 or 2. How can I make this fight more fair and easy for them?

I’m thinking of doing the fight in waves. The first would be the soldiers and two archers, then a wave with just the thugs, and finally there would be an archer, the mage, and the chief. There would probably be a rest period after the first fight.

Any tips?
