The siege of Batesaor back in the days of Nighthelm was pretty large. Its been too many years for me to recall the numbers, but Batesaor was pretty well and doomed. The first war was over in a matter of days when Nighthelm launched a dual strike on both of Batesaor's rurals.
The second war was marked by the infamous "nature walk" Svunnetland and PoZ tried claiming they were taking in the direction of the Nighthelmian army taking Hutael. I believe colored blocks were used to explain Nighthelm's stance on the matter. Them were the days.
