When Daenerys Targaryen first landed in Westeros with the horde of Dothraki, the Unsullied army, Greyjoy fleet, the Tyrells and the Martells along with three full grown dragons, many thought that the Lannisters don't stand a chance. But Queen Cersei didn't think so. She forged an alliance with Euron Greyjoy who is in possession of the greatest armada Westeros has ever seen. And thanks to her brother Jaime she now has Randyll Tarly, one of the greatest battle commanders, by her side. And so the war began. First, Euron defeated the rest of the Greyjoy and Dornish fleet in the epic sea battle and took Yara and Ellaria captive.
Then Jaime and Randyll sacked Highgarden to defeat the Tyrells while leaving a small portion of Lannister soldiers to defend Casterly Rock from the Unsullied. As a result, Daenerys is losing her allies and the Lannisters are returning to King's Landing with the Tyrell gold. However, in the next episode, things are bound to change. You can see the promo for the episode below.
Enough with the clever plans
In the "Game of Thrones" Season 7 Episode 4 teaser preview we see how furious Daenerys is. "My allies are gone. I am losing," she says before finally embracing her inner dragon by saying: "Enough with the clever plans." And this means one thing and one thing only -- Daenerys is going to attack at full force.
And this is a good place to stop for a moment and remember what happened the last time a Targaryen was invading Westeros.
Given the fact how history tends to repeat itself in the "Game of Thrones" universe, let's go back 300 years ago at the time of Aegon's conquest. After successfully defeating Harren the Black at Harrenhall, Aegon Targaryen and his sisters went south to face the Kingdom of the Rock and Kingdom of the Reach and their 60,000 men.
But even though Aegon's army was vastly outnumbered, he still had three fire-breathing beasts which resulted in what later became known as the Field of Fire. The dragons roasted almost 5,000 men on the battlefield including the King of the Reach, Mern Gardener thus extinguishing House Gardener. And King of the Rock, Loren Lannister had no other options than to kneel before Aegon and beg for mercy.
Following his example the King in the North, Torren Stark also bent the knee and the reign of Aegon Targaryen began.
Field of Fire 2.0
If Daenerys is anything like her famous ancestor, things don't look good for House Lannister. In the teaser preview for the next "Game of Thrones" episode we see the Lannister and the Tarly forces heading back to King's Landing. In my opinion, this is where they will get ambushed by the Dothraki. Like facing the Dothraki in the open field isn't bad enough, they will have to face the threat from the sky as well because Daenerys will ride Drogon and the dragon will roast everyone who stands in the way. Thousands of people will die including Randyll Tarly, while Jaime Lannister will most likely get captured once again.
