Lack of rest?

[runequester]

The rules state you should rest 1 turn per 6 (so 10 minutes after every hour of adventuring, basically). What do you rule if they press on?

-1 to attacks and saves seems like one solution (and I may be remembering that from BX D&D). ANother I thought about it to simply deduct 1 HP from everybody.

A low level group with worn and injured characters will need to rest pretty routinely, while higher level characters can push on, but it'll still sap them ever so slightly (and even 5D6 HP is only 15-18 hits on average)

I also penalize any hireling morale checks if regular rests aren't taken.

I would be inclined to reduce damage by -1 (or lower the dice from d8 to d6 for example)
Their AC is reduced by 2 (plate to chain to leather to unarmored)
henchmen morale reduced by 1.

-1 penalties on everything, including morale, plus Move is now 3 regardless of encumbrance. Plus, continuing to press on brings a risk of eventually passing out.

None of that's in the original rules, but it's reasonable.

You could introduce fatigue/subdual/nonlethal damage.

Cooper's method seems a good reading of Chainmail.

For clarity as to B/X, Moldvay says -1 to hit and damage until the characters rest (B19).
