Syzygy hopes to pick them off one by one. Focusing his energies he conjures an orb of pale blue Moonfire (class feature 2x targets withing 5 feet of each other) above the goblin with javelin as well as the sleeping goblin to its left. 

Sacred flame/moonfire: 14 dex save, 4 damage. (autofail for sleeping target)

Then move 3 squares north to take cover in the cave entrance. 

Bryony isn't quite fast enough to reach the goblin that's still awake, but she still flourishes her blades at the creature menacingly, while preparing to dodge any incoming attacks.

After Quinn fired blindly into the thicket, he runs across the stream, nocks another arrow and fires one at the only goblin standing.

move: full movement to get clear line of sight.

action: ranged short bow attack: 6 (1+5=crit fail) for 7 damage.

Sir Roderick moved up to back them up but was confident his young companions could handle some few goblins.

Jurgen will advance up to the goblins and first cast Green-Flame Blade on his dagger and strike the one awake goblin. 

Attack: 12 Damage: 6

(If he successfully strikes the goblin, green fire will leap to the nearby (5') goblin (let's say to the left) )

(Sorry life has been crazy!)

Tessa winds up a golden Eldritch Blast at the closest goblin.

Attack: 6 Damage: 7 force

As Bryony prepares for the next attack, Syzygy's pale blue, flame-like radiance descends upon the chain-shirted javelin-thrower as well as the sleeping goblin next to it. The first goblin tries to leap out of the way:

DC14 javelin-thrower Dex save or take 4 damage: 18

...the other one wakes up screaming, standing and grabbing its bow and shield in a disoriented panic.

Quinn leaps across the stream, charging in behind Bryony and Syzygy. His arrow misses completely, landing deep in the woods beyond.

Tessa runs toward the cave mouth to try to get a glimpse of what's going on. Catching sight of the first goblin, she releases a beam of crackling energy at it, but it narrowly ducks her arcane assault.

The now javelin-less goblin draws its rusty scimitar and dives at Syzygy:
Scimitar Attack #1 vs. Syzygy: 6. Hit: 8 slashing damage.
Scimitar Attack#1 vs. Syzygy: 10.  Hit: 6 slashing damage.

The awakened goblin fires an arrow at Quinn:
Shortbow Attack: 9. Hit: 8 piercing damage.

The third goblin remains asleep.

Jurgen dives across and squeezes between Quinn and Syzygy, his back against the steep stone hillside, then charges the chain-shirted goblin with a flickering green dagger. The goblin deflects it with its shield.

Sir Roderick nods approvingly.

Top of the round!
Bryony, Quinn, Tessa, and Syzygy may act next!

Bryony rushes toward the goblin swinging its scimitar at Syzygy. She strikes first with her shortsword, then with her offhand dagger.

Shortsword - 19 to hit, 6 dmg

Dagger - 23 to hit, 4 dmg

Sneak Attack - 1 dmg

Syzygy reacts and shields the first strike. The second hits hard.

Spotting the chain armour Syzygy reaches out with a shocking grasp.

Metal Advantage, Hit:    (3, 2)+ 6 =9. Damage: 4

Syzygy, hesitating a moment, decides to get out of way the and in a wisp of feathery shadows disappears and reappears on the east bank beside Sir Roderick.

Sir Roderick frowns as his 'proteges' take some hits but they give as good as they got, " Oh, well done, Young Miss Bryony. Smashing good work!"

As Syzygy appears beside him he looks across, " Should I get in there, do you think?"

Bryony pushes through the edge of the scrub and lays into the chief goblin with two blades, cutting it up quite badly.

Nursing a serious wound, Syzygy tries to shock it with his arcane electrical powers, but can't manage to get his hands on the thing. He vanishes from the battlefield.

The scimitar-wielding boss prepares to take on Bryony next, as its comrade nocks another black arrow. (The other continues sleeping.)

Tessa and Quinn may act next (in either order).

Quinn switches to his battle axe and rushes the goblin chief. He swings the heavy axe with two hands and slashes at the goblin diagonally across the chest.

Move: Get into melee range with the goblin chief.

Attack: Melee attack with battle axe (two handed): to hit = 23 (19+4) for 9 damage

Quinn dives into the fray with his axe, wounding the goblin grievously. The creature is beginning to look fearful.

The nervous goblin chief strikes back at Quinn with its scimitar.
Scimitar Attack #1 vs. Quinn: 24. Hit: 3 slashing damage.
Scimitar Attack #2 vs. Quinn: 7. Hit: 5 slashing damage.

The second goblin drops its bow and draws its own scimitar, slashing with it at Bryony:
Scimitar Attack vs. Bryony: 21. Hit: 8 slashing damage.

The third goblin remains fast asleep.

Tessa, Roderick, and Jurgen may act next, in any order.

Sir Roderick charged forward fording the river in a single bound that his knees would make him pay for later, he placed himself at the centre of his three fellow combatants and slashed away.

" Have at thee, Varlet!"

Longsword- Attack: 18 Damage: 9

Sir Roderick charges through the ice-cold stream, but finds he can't quite push through the scrum to deliver his flashy strike.

Tessa and Jurgen may act next, in either order.

Over the sounds of rushing water, Tessa and Quinn distantly hear a dog beginning to bark from somewhere inside the cave.

Jurgen takes a breath to focus his aim this time and again casts his Green-Flame Blade and attacks with his dagger. To Hit 21; Damage 5; and 5 more the goblin next to him.

Jurgen again tries with his arcanely flaming blade to take down the badly-wounded goblin boss. This time he succeeds; slipping the blade past its shield, the goblin goes down hard on its back in the grass. It is dead.

Then the magical green flames leap from the downed goblin to the second attacking goblin. It goes up in a pillar of green flames and then goes down in a smoldering pile next to its comrade. Two dead.

The third goblin slumbers on.

Combat is over! Everyone may act.

Jurgen stumbles back a step and looks at the blood on his dagger. This was the first time he took a life, let alone two, and it hits him hard. He drops to his knees. 

" Whack-O! I knew you lot had the stuff! Excellent work.", Sir Reginald ventured though he kept his blade drawn and pointed at the sleeping goblin.

Syzygy drags himself forward and into view. He sees Jurgen drop to his knees beside the slain goblins. Syzygy recognises that feeling. 

“Sometimes we have to do these things to survive. You did well.” 

“Shall we press on?” He asks the rest of the party.
