Vulmar hears the coming reinforcements and considers trying to send them into a slumber - but he can't get a good line of sight to his targets.  Instead he focuses inwards, calling on his deeper reserves of magic.  Then he turns around to keep an eye on the other end of the tunnel - he didn't want to get flanked here and they were making quite a bit of noise.

(Converting Sorcery Points to spell slots, but taking no other action this turn.)

Duncan will stand by this Bugbear, continuing to dodge until it goes down. If it drops before his turn though, he takes a deep breath and runs to where the voices are coming from, trying to hold them by dodging their attacks hoping his companions can finish them quickly.

Orro again sacred flame’s the next bugbear for 5

Kayassa sends another blast of eldritch energy that hits the bugbear square in the chest yet again (-7hp [Total: -19hp]).

However, you then turn to catch the north door open, a Redbrands soldier shakily draws his weapon in the doorway, and you can see the shape of three more behind him. One thing of note, the Redbrands do appear visibly intoxicated as if they have been drinking. Initiative: 7    
New Initiative Order: Vulmar, Redbrands, Daphina, Orro, Duncan, Bugbears, Kayassa

Vulmar sees the Redbrands enter, and prepares to cast a spell on them. 

The Redbrands in the doorway will take two halfhearted strikes at Kayassa— the closest to him— with his shortsword. 
Attack: 10 Damage: 5 and Attack: 23 Damage: 6   
However, you are able to easily dodge both attacks (Miss).

Daphina not having much else to do with no more ranged weapons or a way to reach melee combat will help Duncan, giving him advantage on all attacks made this round. 

Orro casts sacred flame on the closest bugbear once again. (Dex Save: 5). The bugbear gives a grunt as the flame engulfs its body (-5hp [Total: -24]). 

Duncan continues to dodge all incoming attacks. 

The bugbear closest to the doorway will once again make an attack with its Morningstar against Duncan, again also with disadvantage. 
Attack: 16 Damage: 12   
And the attack yet again misses.

Kayassa is up! Bless is still active, so Kayassa, Daphina, and Duncan may all add a d4 to attack rolls, and Duncan has advantage on attack rolls. Please go ahead and make your round 3 action, an as always, everyone else may queue their round 4 actions.

Mao has been updated, and is on the doc. There are still two bugbears left, one severely injured, and now 4 un injured but drunk Redbrand soldiers on the other side. What would you like to do?

Kayassa will continue her assault on the injured Bugbear, frowning since it still seems to be able to stand. As before the energy forms in her hand, crackling as it flies towards the target.

Eldritch Blast: Attack: 12 Damage: 5

Bless: 2

Seeing the help offered by his companion, Duncan decides that perhaps offense is better than defense here. He then takes a couple swings at the nearest enemy.

Orro's eyes widen at the fusillade aimed at the bugbears. He turns and faces the new arrivals. He points at the lead Redbrand and says, "You want to lay down your arms and not start anything hasty or you'll all burn. NOW!" He casts sacred flame at them for 2 radiant damage.

Intimidation: 6

Vulmar glances around - the party was flanked.  This was a terrible place to fight and he couldn't get a good view of either group of enemies.  He retreats 15 feet to the East, hugging the North wall so the party could pass by if necessary.

(Still can't see anybody, passing the turn.)

Kayassa yet again sends an eldritch blast to hit the injured bugbear, and this time it strikes true and indeed knocks the creature unconscious. 

Vulmar again moves back due to his awkward position while the Redbrand closest to the group again takes two drunken swipes at Kayassa   
Attack: 9 Damage: Unable to parse dice roll. and Attack: 11 Damage: 7 Both attacks however miss again. 

Daphina again will help Duncan 

Orro casts sacred flame again at the Redbrand in front while trying to intimidate them as well. (Dex Save: 10) the leader extinguishes the flames and simply seems more infuriated that he cannot land a strike against Kayassa. The intimidation is unsuccessful. 

Duncan then attacks the third and final bugbear with a vicious ferocity that leads blood spurting across the room, but the weakened bugbear is still nearly standing (-24 hp).

The bugbear however retaliates with its own vicious strike back against Duncan.
Attack: 13 Damage: 10 However, Duncan is efficiently able to again block the strike with his glaive. 

Kayassa is up again. Go ahead and make your round 4 actions, while as usual everyone else can queue their actions for the next round. Bless is still active on Daphina, Duncan, and Kayassa providing an extra d4 to attack rolls, and Duncan also has advantage. Map is updated; what would you like to do?

Seeing that one of the Redbrand is now on top of her, Kayassa curses since it is to close for her spell. With quick movements she draws a dagger from her belt and tries to stab at the drunkard.

Dagger: Attack: 20 Damage: 10

Bless: 1

So yeah dice roller screwed up so the damage should be 7

(On his turn) Duncan will continue to use the help given by his companion. He can’t hold a line that didn’t exist, so it’s best to try to end things as quickly as possible. If the bugbear is down he’ll charge at the next nearest enemy.

Orro again calls down sacred flame on the lead Redbrand for  5 radiant damage.

Vulmar realizes that his allies aren't retreating from the fatal funnel.  Frustrated, he moves 20 feet back towards them.  If the last bugbear is dead by his turn, he will Dash into the room they were in.  If Duncan has not yet dispatched it, he will Ready the Dash Action to move in once he can.

(Sorry for such a late response, things have been incredibly busy lately)

Kayassa quickly draws a dagger and deftly stabs the closest Redbrand who grunts with pain (-4hp). 

Vulmar moves back to the group... and is ready to dash into the nearby room. 

The Redbrand leader takes two more strikes at Kayassa. 
Attack: 12 Damage: 3 and Attack: 13 Damage: 4   
This time however, one of the lazy strikes catches the nimble Satyr, drawing blood from a shallow wound across your chest (-7hp).

Daphina will also ready herself to dash into the room after Duncan takes out the final bugbear. 

Orro casts sacred flame at the lead Redbrand again. (Dex Save: 5)   
Again, the leader dodges the flames.

Duncan with a well timed glaive strike is able to slice through the chest of the final injured bugbear, defeating the beast. Then, both Daphina and Vulmar are able to rush into the room, dodging the three fallen corpses. Daphina also retrieves her two fallen daggers on the way there. Unfortunately, Duncan, you would not be able to move to attack the Redbrands due to the confined nature of the hall, but you can move past Orro to get closer to the front lines.
One thing of note, Vulmar and Daphina. In the room towards the back, you see the form of what appears to be an unconscious goblin laying on the floor. It has no injuries of any sort, but is nonetheless not conscious. 

Kayassa is up! Everyone else may also queue their actions for the next round. There are now only 4 Redbrands left to fight, one injured. Bless is still active on Daphina, Kayassa, and Duncan. Map has been updated, what would you like to do?

Kayassa hisses in pain as she is cut, muttering something as she cast Hellish Rebuke as a reaction to the attack. The Redbrand needs to make a dc 14 Dex Save or take 15 Fire damage or half if they succeed.

Once her spell is done she will ready her dagger once more and aim a stab at the Redbrand if they are still alive. If not she will move to the nearest and stab at them.

Dagger: Attack: 24 Damage: 4

Bless: 4

Having collected her daggers, Daphina grins at the Redbrand’s, and throws a dagger at one.

Attack: 23 Damage: 8

Dex Save: 3

After drawing Kayassa’s blood, the thug erupts into flames with a cry of pain. The smell of burnt flesh begins to fill the room (-7hp (Total: -11hp)). 

Kayassa then retaliates again with a dagger, but it does not penetrate the simple leather armor that the Redbrand wears (Miss). After that, you would then be able to move backwards, and Duncan is able to take Kayassa’s place at the front lines. 

Waiting on a move from Vulmar! Then will update. What would you like to do?

Orro gives up on the sacred flaming and pulls out his crossbow. It's not his strength, but it might be better than the alternative. He aims at the redbrand he can see.

Attack: 14 Damage: 4

(Alright, will go ahead and post Vulmar’s action)

Vulmar will hurl another fire bolt at the Redbrand in front. 
Attack: 21 Damage: 9 The attack hits and further injures the Redbrand (-3hp (Total: -14hp))

Then the Redbrand takes two swipes with disadvantage at Duncan who has now moved in front of Kayassa. 
Attack: 18 Damage: 4 and Attack: 7 Damage: 7   
both attacks however are blocked by Duncan, the second one coming narrowly close to slashing through your stomach.

Daphina flicks a dagger towards the thug that embeds itself in his shoulder, causing him to fall backwards with a gurgle of blood.

Orro takes out his crossbow and fires it at the new Redbrand that rushed forward in the last ones place. It sinks an inch or two into the thug, making contact (-7hp). 

Duncan is up! Kayassa may also make her action for the turn, and Vulmar can queue his action for the next round. Bless is still active for Daphina, Duncan, and Kayassa... the map has been updated. What would you like to do?

Kayassa is a going to move back, muttering as she does so. As before the force of the Fey Magic forms in her hand. With one last word she fires her Eldritch Blast.

Eldritch Blast: Attack: 23 Damage: 13

Bless: 1
