Moreover, in our desire to bring the game to a climax, we decided that instead of a fight to a finish we would fight to some determined point, and we found very good sport in supposing that the arrival of three men of one force upon the back line of the opponent's side of the country was of such strategic importance as to determine the battle. But this form of battle we have since largely abandoned in favour of the old fight to a finish again. We found it led to one type of battle only, a massed rush at the antagonist's line, and that our arrangements of time-limits and capture and so forth had eliminated most of the concluding drag upon the game.

Our game was now very much in its present form. We considered at various times the possibility of introducing some complication due to the bringing up of ammunition or supplies generally, and we decided that it would add little to the interest or reality of the game. Our battles are little brisk fights in which one may suppose that all the ammunition and food needed are carried by the men themselves.

But our latest development has been in the direction of killing hand to hand or taking prisoners. We found it necessary to distinguish between an isolated force and a force that was merely a projecting part of a larger force. We made a definition of isolation. After a considerable amount of trials we decided that a man or a detachment shall be considered to be isolated when there is less than half its number of its own side within a move of it. Now, in actual civilised warfare small detached bodies do not sell their lives dearly; a considerably larger force is able to make them prisoners without difficulty. Accordingly we decided that if a blue force, for example, has one or more men isolated, and a red for
