Victoria Rules
Well, there is, but it takes some interpretation and combining of different bits and pieces.Undoubtedly, but D&D (nor even AD&D) presented any solid rules for how to do that. I mean, there are 'heuristics' effectively like spell ranges and AoEs, but if you read the 1e DMG combat chapter, there's NO SUCH THING as a specific 'square' or 'hex' in which a specific character is to be found!

The 1e DMG talks of facing, and of how much space a character "occupies", and so forth; but leaves things like moving through an occupied area largely up to the DM.
We've been playing it using grid and minis since before I started (1982), using judgment calls when it comes to who can fit and-or move where but using move speed to determine how far people can go and the position/facing of the minis to determine who is where at any given time. We've never made it anywhere near as formalized as 3-4-5e have it, though.There are no rules for moving from one place to another (albeit there's a movement rate, and you can extrapolate some 'rules' from concepts like the poorly explained idea of being 'engaged'). So, I believe you can play 1e or 2e AD&D on a grid and utilize the ranges and such that are provided, but a LOT of what in a game like 3e, or 4e would be regulated by the rules, is simply up in the air and decided by the GM, grid/map or no grid/map.
