How long did you boil them? Just skimming some recipies on foodnetwork.com here, haven't found any specifically doing what you're talking about, but a few of them call for boiled chestnuts (and other vegetables) with boiling times up to 45 minutes or longer.
Alternately, if you're feeling a little more adventurous, could you try oven-roasting them? Just wrap them in a little aluminum foil and leave them in a medium-hot oven (350? 375?) ... probably start checking on them after 45 minutes or so and keep going as long as needed. You could either try to roast them dry, or drizzle them with a little olive or vegetable oil before you wrap and roast them, depending on how you want the finished product to taste ...
Just some thoughts.
(While the chestnuts are roasting ... might as well wrap a trimmed bulb or a few peeled cloves of garlic with some olive oil and roast those too, spread 'em on a piece of toast ... mmmm mmmm.)
