The Wars of the Roses were a series of battles fought in the 15th Century between the houses of York and Lancaster for the throne of England.
The battles were:
St Alban’s: 22nd May 1455: Yorkist victory 
Blore Heath: 23rd September 1459: Yorkist victory
Ludford Bridge: 12th October 1459: Lancastrian victory
Northampton: 10th July 1460: Yorkist victory

That was 11 to the Yorkists and 6 to the Lancastrians although the Lancastrians ultimately won.
And I took the photos of the lovely roses in the new rose garden at Dunham Massey.
Love the Wars of the Roses – they had such a massive impact on English history! Sometimes I wonder how things would be if York had won at the end?
If you get a chance you should visit the Battlefield Heritage Centre at Bosworth in Leicestershire. It’s a great exhibition detailing the battle and has an exhibition of the weapons and finds from the battle. http://vikingladyaine.wordpress.com/2013/07/09/bosworth-field-2/
I’ve been to the battlefield centre at Bosworth a couple of times – and you’re right, it is fascinating.
