Which Lords/Kings fight their own battles, and which don't?

[BaseBornBastard]

One striking difference between House leaders is that there are many who, during times of war, pick up their swords get in the thick of the action and many who choose to either lead from the back or simply stay in their castles, The are of course many Lords who are incapable of taking direct part in the violence due to old age and other issues, and perhaps some that are capable but choose stay holed up. I this this distinction can be very telling as to the type of Lord/King this individual is. Lets figure out who goes where....

Y=Yes (they take up arms)

N=No (they let others do the killing)

Ned Stark - Y

Robert Baratheon - Y

Hoster Tully - ?

Jon Arryn - ?

Rhaegar Targaryen - Y

Doran Martell - N

Aerys Targaryen - N

Mace Tyrell - ?

Tywin Lannister ? (though I can't imagine him swinging a sword)

Jon Connington - Y

Randyll Tarly - Y

Walder Frey - N

Stannis Baratheon - Y

Renly Baratheon - N

Robb Stark - Y

Balon Greyjoy - N

Joffrey Hill - N

Tommen Hill - N (obviously)

Lyn Corbray - Y

Yohn Royce - Y

Rickard Karstark - Y

Greatjon Umber - Y

Roose Bolton - Y

Wyman Manderly - N

Feel free to add/correct.

Huster Tully - Y. Catelyn's "Wait for me Cat", and Jon Con injured him at the Battle of the Bells.

Jon Arryn - Y. Battles of Gulltown, the Bells, and the Trident.

Aerys - Y. Went to Duskendale, only shut up in his keep after the Defiance of Duslendale had shattered his mind.

Tywin Lannister - Y. Tyrion sees him lead the final assault against the remanents of Roose's host at the Battle of the Green Fork.

Mace Tyrell - Y. Only goes with a huge army. A point to consider - The only charachter that learns and when a family member is charged for crimes in KL, he actually arrives with an army, instead of with a small retinue, like oh so many dead lords.

Renly Baratheon - Y. Not placed in the Vanguard, but still planned to fight in the battle against Stannis, the reason he was putting on armor just before the shadow.

Balon Greyjoy - Y, in the day. Nowdays he prefered to let his family members do all the workk, and all the glory will go to him as the king.

Basically, only Doran and Tommen can't realy go, and only Walder Frey refuses to fight his own battles. Some prefer to lead from the front, some from the reserve, but nearly all fight their own battles.
