I've been out of the hobby for over a year now and have been itching to get back to it. I had started a Low Countries army some time ago and would like to finish it. Looking through the list, I have or know what I need to finish it except for Feudal Levy (7Hd) and "Whitehoods" (5Hd). I'd like to stay with Essex as the original army is an Essex DBA 2.2 army pack.
I'm afraid I can't offer any meangful suggests. If I had a copy of the WRG or perhaps an Osprey I would look at this in the first instance. I would use this as a basis of looking for figures in the Essex ranges.
The White hoods were effectively something like a political party. There is a depiction of them in a version of Froissart www.lead-adventure.de/index.php?topic=80780.0 where the hoods are worn as hats. Despite the given date of 1379, I think that is actually a 15th illustration.
