Walt see’s the old man stumble to the ground and his friends react to what’s unfolding. He adjusts his position in the wagon and calls out “careful! There more than one!” Walt reaches into his pouch, pulls out a dried stem of a plant with thorns, holding it in his hands as he stands ready for any threats. 

Ready action: Walt will cast thorn whip on any threat that breaks through the crops and attacks Baldar or the old man.

To hit: 18
Damage:6

Continuation…

If Walt attacks any threats, he will pull them 10 ft towards himself. 

Three massive animals spring out of the crops and toward the old man, but they immediately spot the wagon. Your horses rear up in fright. 
"Coyotes!" shouts Lady Dre as she pulls a longbow out from inside the wagon. The Proclaimer stands up in the wagon to get a better look.

Roll initiative!

Giant coyotes: 20
Old Man: 5
Lady Dre: 12
Tungsten Ward: 3

Tuuli’s initiative: 13 

Lucky’s initiative: 7 

Bendrak initiative: 15

Walt  initiative: 7

Baldar immediately swings her battleaxe at the lead coyote to protect the fallen man.

Baldar Battleaxe attack vs. Giant Coyote: 19  Hit: 10 slashing damage

Walt casts thorn whip.  To hit: 24. Damage: 1.   He wrenches the massive beast closer.

Baldar initiative: 0

Baldar tears a serious wound in the side of the leading coyote.

Two of the massive creatures tear into Baldar. The third pounces upon the prone farmer.

Bite Attack #1 vs Baldar: 6  Hit: 9 piercing damage (and must succeed on a DC 13 Strength saving throw or be knocked prone.)
Bite Attack #2 vs Baldar: 25  Hit: 10 piercing damage (and must succeed on a DC 13 Strength saving throw or be knocked prone.)
Bite Attack #3 vs old man: 9  Hit: 10 piercing damage.

Baldar is uninjured and maintains her balance against the massive coyotes.

The old man is not as lucky. The coyote tears open his shoulder and neck, mauling one arm badly. He is rendered unconscious and bleeding badly.

Initiative:
√ Coyote 20
   Lucky 21
   Bendrak 15
   Walt 15
   Lady Dre 12
   Tuuli 11
   Old Man 5
   Tungsten Ward 3
   Baldar 0

Everyone may act (in any order.)

Lucky hightails it (literally!) due north into the fields, and attempts to hide. Stealth: 22 

(Dang, the cat goes virtually invisible.)

Tuuli balances on the wagon and draws her bow, arrow to her cheek, sights carefully, and lets it fly, a breath of wind helping it fly true.

(That's just poetic license flavoring the Steady Aim feature.)

Move: No, for Steady Aim
Bonus Action: Steady Aim for Advantage
Action: shoot well wounded coyote with Advantage and thus Sneak Damage: 23 to hit, for 13 piercing 

Reaction: reserved for Shield 

Bendrak leaps forward and charges the coyote who has injured the old man with a fearsome roar.

Attack: 16 Damage: 16

With Menacing Attack maneuver. Bonus damage and DC13 WIS save or target is frightened of Bendrak.

Walt casts magic stone as a bonus action on 3 stones in his pouch. 

He leans over the side of the wagon, pulls a smooth dark river stone from his pouch that shimmers with magical energy, takes aim at the coyote immediately to the left of Baldar and throws the stone at the beast. 

Attack 6 for 9 damage. 

Surrounded on all sides, Baldar uses her shield to rebuff the attacks against her, but despite her best efforts, is unable to do the same for the poor old man. Trusting that her allies will continue to throw everything they have at the coyotes, she leans over the man and drops her axe then places the free hand above his wounds. "Yer not dyin' yet. Not on my watch." An ethereal glow appears in the gap, covering the wounds and then expanding to cover the entire form of the man, providing a shield around him. "Don't move. I will protect ye."

ACTION: Lay on Hands for the old man to restore 5HP
BONUS ACTION: Casting Sanctuary on the old man
MOVEMENT: None

Lucky vanishes into the crops.

Tuuli sinks an arrow deep into the wounded coyote. Badly injured, it continues to advance.

Bendrak aggressively charges the second coyote which mauled the old man. It is seriously wounded. DC13 Wisdom Save: 18 or be frightened of Bendrak.

Walt lets fly one of his arcane-imbued rocks, but it flies high overhead.

Baldar staunches the old man's gory wounds and somehow revives him.

Lady Dre tries to calm the panicking horses. Animal Handling: 9

The Proclaimer pulls a flame-like radiance down upon the advancing coyote. DC12 Dexterity saving throw: 14 or take 2 radiant damage.

The second coyote ignores Bendrak's bravado even as the first dodges the Proclaimer's divine radiance. The horses continue to rear up in fright.

-- Top of the Round --

The coyotes ignore the old man and go after Baldar and Bendrak:

Bite Attack #1 vs. Baldar: 23 Hit: 7 piercing damage and must succeed on a DC 13 Strength saving throw or be knocked prone.
Bite Attack #3 vs. Baldar: 17 Hit: 11 piercing damage and must succeed on a DC 13 Strength saving throw or be knocked prone.
Bite Attack #2 vs. Bendrak: 25 Hit: 10 piercing damage and must succeed on a DC 13 Strength saving throw or be knocked prone.

Baldar and Bendrak each take nasty bites and struggle to keep on their feet as the beasts try to knock them down (make DC13 Strength saves.)

Everyone may act.

Lucky skitters up to the most wounded coyote, trying to keep himself free from melee with any of the other coyotes, while Tuuli, seeing a problem brewing with the horses, hops down from the cart (to the east) moving away from it and the horses a bit.

Static crackles around her as she looks back at the fight. “Good kitty.”

Lucky attempts to put a paw on the coyote, his own fur starting to crackle.

—
Lucky (init 21) moves, and stops in melee range of the most wounded coyote.

Tuuli (at a lower init than Lucky) moves east of the cart two squares, then casts Shocking Grasp. Her turn is over (saving Reaction for Shield again).

Lucky uses his Reaction to try to touch the coyote to deliver the Shocking Grasp. Cats make melee attacks at +0, so I’m going with that. Attack: 19 Damage: 6 lightning damage (and no reactions until start of its turn). 

Bendrak

Strength save: 10

Walt exits the back of the wagon and positions himself on right side along the tree-line. Just then he see's Bendrak take a nasty bite from a coyote and fall prone. Walt shouts out an incantation in the druidic language and casts healing word on his friend. He then pulls out another magic stone from his pouch, this one a jagged hunk of granite, and hurls it at the coyote that attacked Bendrak.

Bonus Action: Casthealing word on Bendrak for 4 HP

Action: 22 to hit for 4 damage
