England never hold any and we're surrounded by hostile nations, so tournaments aren't as available right now
I won a tournament and bought that great helm with the prize money.
EDIT:
Yes, I changed my coat of arms. I didn't really like the shade of blue my first one was (I enjoy heraldry!) and I was having trouble finding a surcoat/horse barding that went with it. I saved up my ransom money to buy my horse/armour
The French invaded again and Bishop Walter was, yet again, being an idiot, so I spoke to Archbishop Boniface and we agreed he should no longer be marshal. Now, Richard de Clare is the marshal. He got into a spot of bother with the as-of-yet unchecked French army which made landfall in England, so it was time to help.
After being unhorsed, I led an infantry charge which finally managed to get in amongst those pesky French crossbowmen
...and barely escaped with my life once the French cavalry realised what was happening....
We won in the end! However, I was wounded and had to finish the battle as one of my crossbowmen and a farmer with a scythe
EDIT again:
I have just looked it up in my big book on heraldry: apparently my new crest was historical and was borne by a man called Langton (first name unknown?), the baron of Walton, who was knighted in 1348.
