"Barons War - Standards?" Topic

Anyone have ideas on the following

1. The Dragon Standard – Found this description, but not drawings – The dragon standard associated with Edward I was a highly symbolic and ornate war banner, often described as being made of red samite (a luxurious silk fabric) and lavishly embroidered with gold

2. "Army Standard" used by Montfort. Supposed to be different than Montfort's personal standard.

The dragon standard was probably the banner of England's old patron saint, St Edmund. Exactly what it looked like no-one probably knows but here's a good one:

As for Simon's battle banner, all I could find was this:

You can just see one interpretation of the dragon standard on the front cover of the Osprey "Lewes and Evesham", carried by the guy at extreme right – link

BillyNM – the red-and-white banner you reference is borne by de Montfort in a stained glass window in Chartres cathedral – picture – it is apparently the arms of the honour of Hinckley, so more of a personal than an army standard:

"Nichols in his History and Antiquities of Hinckley, in the County of Leicester (1782) mentions the "valuable volume of records belonging to the office of the Duchy of Lancaster (…) [with] the blazonry of the ducal arms, accompanied by the banners of the various lordships which centered in that distinguished title. Among these is the banner borne by the old earls of Leicester in right of their honour of Hinckley, viz. Party per pale indented, argent and gules" – from PDF link

But no reason why it couldn't have been used a battle banner?

It could certainly have been carried in battle, but it doesn't seem a good choice for an "army standard" – it has less significance than even the usual Montfort lion.
