LIVE POLL: "Game of Thrones" - Most Exciting Battle

Game of Thrones, The Watchers on the Wall
Sack of Mole's Town
Wilding raiders attack Mole's Town and Gilly escapes in 4.8 episode "The Mountain and the Viper"

Nikolaj Coster-Waldau Game of Thrones, Baelor
Battle of Whispering Woods
Jamie Lannister led army defeated and Jamie captured in 1.9 episode "Baelor"

Alfie Allen, Gemma Whelan Winterfell, Game of Thrones
Rescue of Yara Greyjoy

Home, Game of Thrones
Retaking of the Iron Islands
Varys reports Yara has retaken the Iron Islands in 8.4 episode "The Last of the Starks"

Definitely, Massacre at Hardhome is in the the top tier; I hope there might be a couple on tap that might give it a run for the money.

Changed my mind. 

Battle of Eastwatch-by-the-Sea

I suspect the upcoming season might entice more than a couple changes too. It should be interesting to see which on the top characters will make it to the final scene.

I updated spoiler alert to reflect season eight scheduling for 2019 calendar year.

SPOILER ALERT: Intended for viewers current through the 2017 season as poll reveals depicted or discussed Game of Thrones battle plot points, participants and outcomes through the end of 2018.

Thanks, corrected.
