The most gruesome 'Game of Thrones' battles, ranked

As the Lannister army traveled back to King's Landing with the spoils of their Highgarden victory, Daenerys and Drogon caught the army off guard and extinguished most of the Lannister Army, sparing few.

The battle didn't last long, but Daenerys wrought havoc and showed the Lannister's just how powerful and dangerous she can be.

Battle of the Blackwater was the largest battle during the War of the Five Kings.

The use of wildfire, a deadly chemical that instantly sparks into green tinted flames, made this battle especially intense and deadly.

The wildfire blew Stannis Baratheon's ships to smithereens as he and his army tried to take King's Landing. A few men (including Stannis) survived the wildfire attack, making it to King's Landing's mainland, only to be slaughtered by the soldier's defending King's Landing.

Stannis managed to survive the wildfire attack, but met his fate shortly after.

Jon Snow defends Winterfell from Ramsay Bolton, but the credit really should go to Sansa for winning this battle.

Sansa calls upon the Knights of the Vale to fight for her, who then show up at the last-minute when it looks like all is lost.

Jon Snow and Tormund Giantsbane, along with other members of the Night's Watch, travel to the Wildling town of Hardhome to ask the Wildlings for their alliance in the impending war against the White Walkers.

The Wildlings, despite being resistant at first, eventually agree to help Jon Snow and the Night's Watch. As the Night's Watch and Wildlings begin to set course for the North (or, South for the Wildlings), the army of White Walkers and wights attack them.

The battle results in the death of many Wildlings and Night's Watch men, with Jon Snow and Tormund Giantsbane narrowly escaping.

This epic battle between Daenerys and the White Walker and wight army is a thrilling collision of worlds.

Ser Jorah, Jon Snow, and the Brotherhood Without Banners get stranded on a frozen lake surrounded by the army of the undead, and Daenerys flies beyond The Wall to rescue them. The dragons incinerate the army, enabling her to save the men stranded.

But the battle ends on a tragic note when one of her beloved dragons, Viserion, is killed by the Night King, when it's hit by one of his ice spears.

It's kind of hard to consider a battle where dead people are being killed gruesome, but this is a monumental battle of great significance, and the beginning of the Great War between man and the undead.

The Battle of Meereen accounts for the third and final major battle in Daenerys' takeover of Slaver's Bay.

Daenerys incentivizes the slaves of Meereen to rise up against their masters to gain their freedom. Together with the Unsullied, the slaves of Meereen slaughter a large majority of the masters of Meereen, while Daenerys' dragons set their slave ships aflame.

Daenerys then begins to rule as the Queen of Meereen.

After conquering the city of Yunkai on her quest to liberate all of Slaver's Bay, Daenerys makes an attempt to eradicate slavery in Meereen. Daenerys frees the pit fighters of the Daznak Pit, all of whom are slaves, which angers former slave holders.

The Wise Masters of Yunkai rise back into power and reestablish slavery, bringing back the fighting pits. When Daenerys learns about this she attempts to abolish slavery and the fighting pits once more. Unfortunately Daenerys' attempts to rid Meereen of slavery results in the formation of a group called the Sons of the Harpy, who kill her Queen's Guard in a form of protest.

In an attempt to halt the violence, Daenerys agrees to reopen the fighting pits, but on the day of the pits reopening, the Sons of the Harpy attempt to kill the queen.

The Sons of the Harpy are unsuccessful in their attack. Daenerys' dragons burn them alive, saving the Queen.

Not really a battle, but the insane use of firepower (or, dragonpower) and violence gets this attack a spot on the list.

Mance Rayder, the King-Beyond-the-Wall, attacks Castle Black along with his band of Wildlings. The battle seems never ending, as members of the Night's Watch battle wildlings without taking a breath.

A lot of the Night's watch are killed by the Wildlings, along with Jon Snow's Wildling love interest Ygritte. The Night's Watch is saved from defeat when Stannis leads his army in a sneak attack.

While on their voyage to Dorne to collect Dornish soldiers to fight on behalf of Daenerys' cause, Yara and Theon Greyjoy's fleet of ships is attacked by their uncle Euron Greyjoy.

Ellaria Sand and her fellow Sand Snakes are also aboard the ship. Half of the Sand Snakes are slaughtered and hung off the side of the ship, while Ellaria and her daughter Nymeria are taken hostage.

Euron then sets Yara and Theon's ships ablaze, and slaughters nearly ever person he comes across, with the exception of Yara, whom he keeps as his prisoner. Overwhelmed by the abundance of bloodshed, Theon jumps ship, leaving his sister behind.

Stannis brings his army to Winterfell during an attempt to take it from the then self-appointed King in the North, Roose Bolton.

The Battle of Winterfell is one of the last battles in the War of the Five Kings, ending with the death of Stannis.

This is the first of three attacks that Daenerys makes on Slaver's Bay in an attempt to eradicate all slavery, and cultivate an army for herself.

Daenerys heads to Astapor to obtain the Unsullied army, as her dragons are not big enough to help her conquer Westeros yet.

Daenerys pretends to sell Drogon to the Good Masters of Astapor in order to buy the Unsullied army. Once she has ensured that the Unsullied have pledged themselves to her she orders them to attack the Good Masters.

Daenerys instructs the Unsullied to kill any slave owner they find, and free any slaves they come across. After the attack, Daenerys frees the Unsullied, but they decide to follow Daenerys as freedmen.

In the brief attack on Casterly Rock, the Unsullied take the once untakeable city with ease.

But the Unsullied realize shortly after their victory that the Lannister army is not fully present, and that they've been tricked. This becomes especially clear to the leader of the Unsullied army, Grey Worm, when he sees one of Euron Greyjoy's ships burning their ships, trapping them on Casterly Rock.

While the Unsullied army takes Casterly Rock, the entire Lannister army travels to take Highgarden.

The battle is swift, and the Lannister army is quick to take all of Highgarden's resources back to King's Landing.

The Battle of Yunkai marks Daenerys' second battle in Slaver's Bay. Daenerys sends Daario Naharis, Ser Jorah Mormont, and Grey Worm into the city of Yunkai to kill the guards, leading the Unsullied army in to siege the city.

We see the three soldiers slaughter the guards, and the army flood into the city, but not much else.

Ser Jorah returns to Daenerys with the news of their victory, bringing Daenerys one step closer to freeing all of Slaver's Bay.

Robb Stark leads House Stark to victory in this triumphant battle against House Lannister.

Just like the Battle of the Green Fork, this battle happens offscreen, so the audience can only guess how brutal the battle was based on the aftermath.

Tyrion gets knocked unconscious within the first few seconds of this battle, and when he comes to, it's all over.

The audience can only imagine what the battle entailed — but the aftermath did look pretty grizzly.
