In OD&D and AD&D 1E melee combat was an abstract chaotic event. One couldn't choose specific targets. Targets were selectable for missile fire only. Thus what was "protecting" the squishy magic user in melee combat was pure luck. <snip>
1) More fighters means an actual physical barrier between enemies and the magic user. To be considered a possible target, the enemy must be able to reach the magic user.
2) Simple odds. If you have one fighter protecting the magic user and enemies can reach you then the magic user has a 50% chance of being the target. If you have four fighters doing the same then the chances go down to 20%.
The reason for large parties of mercenaries should now be readily apparent.![]()
Interesting. Since I live in Ireland, the playstyle here evolved directly from the rulebooks, without reference to unspoken elements of the intended playstyle. Therefore, my early experiences of 1e gravitated away from "mercenary band" to "small adventuring party of equals" from the very start, which was more in keeping with the inspirational novels and the illustrations used. Attempts to use wardogs, hirelings etc were discouraged by making them ineffective or just wiping them out.
Enemies often came in large numbers and were assigned to attack the party evenly, barring a convenient battle-line or dungeon bottleneck. Dungeoneering was safer than being in the open, which reflects their separate treatment at the time.
