In addition to trying to bring down a city's walls with battering rams, Roman legions might build a wooden structure higher than the battlements, which would then be ignited and collapsed down over the fortifications. This, of course, required a good supply of wood, and also a flammable city. Many cities obliged by burning quite dramatically.
I'm still deciding on how to add some sort of stabby scene in row 1 in between panels 2 and 3. I've learned I'm not very good at drawing stabby scenes.
