Some thoughts on warfare in Westeros
So I’ve seen a bit of meta recently about how warfare in ASOIAF is much more brutal than the equivalent at the same period of medieval history. Now, I’m not 100% convinced that every cristicism on this level is valid for a number of reasons.The main two reasons that Westerosi history deviates from European history in a few main ways- firstly, there is no "black death" equivalent, secondly, despite what we are told about St George, there are no dragons in Medieval Europe.
Looking at England at the time of the war of the roses, that started not long after the hundred years war, which lasted about 80 years, and during that period there was also the black death and the peasant’s revolt, and before the hundred years war, there was a period of fighting with Scotland (wars of Scottish independence) and Wales, and things weren’t exactly peaceful before that. Medieval England at the time of the war of the roses (which is seen as the most direct comparison for the events in ASOIAF) is actually in a very different state to Westeros before Robert's rebellion.
I think there are two main differences between our world and Westeros which can account for this. The first is the lack of a significant plague, like the black death, so population levels would probably have been higher. The thing about the black death/plague is whilst the most serious period ended in Europe in about 1350, it kept reoccurring, right up to the great plague of London (1665) and beyond. Some of these periods of reoccurrence had pretty high death tolls of 10-20% of the population, too.
In Westeros, there’s no real comparable plagues/diseases. Yes, we do hear about some periods of plague, such as the great spring sickness, but the effect of this on the population was not so severe. In the Sworn Sword, it says tens of thousands of people died. In the great plague of London, over 100,000 people were estimated to die in one city. Anyway, the great spring sickness is a one off event that occured about 100 years before the events of the main series, and didn’t kill nearly as many people, so it’s not comparable to the black death.
From this, it could be concluded that the peasant population of Westeros is comparatively higher than the peasant population of England/Europe at a similar time period.
There’s also a second major difference between Westeros and Medieval Europe. In Westeros, there were dragons. Yes, at the time of the series, dragons haven’t played a role in Westerosi warfare for roughly 150 years, but they also did play a role in the warfare of the Seven Kingdoms for at least as long, if not longer. We don’t know if the Targaryens ever got involved in Westerosi disputes before Aegon’s landing, but it’s not impossible.
The thing about dragons is that they are basically weapons of mass destruction. One dragon can easily wipe out an entire village or a huge number of soldiers- as demonstrated in the Princess and the Queen novella. I would say there is no sort of weapon that existed in the Medieval period which is close to being comparable. Cannons and gunpowder could destroy buildings, but you’d need a lot of them to match up to the level of destruction a dragon can cause, and they are nowhere near as mobile.
So, warfare in the seven kingdoms has developed in the presence of dragons, and if you are going to fight against a dragon (which at various points people have seemed willing to do), you have to expect heavy losses. Therefore, a style of warfare developed where the peasant soldiers were mostly seen as expendable. This is probably why in Westeros we don’t really see any groups of people comparable to English bowmen or Swiss Pikemen (who came a bit later than the hundred years war, but not majorly so).
I think what we see in people destroying whole villages and having hugely fatal battles in the war of the five kings and beyond is realistic for a society where warfare has been influenced by the presence of dragons. The Targaryens probably regularly used the threat of destroying villages to keep order. There’s also not a lack of peasants, as there was in the aftermath of the black death, and no threat of recurrent plagues. After the long summer, the population of Westeros is probably quite healthy, maybe even too dense in some areas- therefore rich lords like Tywin Lannister and Mace Tyrell don’t care if thousands of peasants die.
I don’t know if GRRM planned this deliberately, but I think the warfare that exists in Westeros is realistic for a society that was up until relatively recently having to contend with dragons being used in warfare.
