						The prototype 
						PORTABLE WARGAME was made from an old wooden chessboard. 
						The board was also the lid of a wooden box that had been 
						used to store the chessmen when the game was not in use. 
						This space proved ideal for storing the figures, dice, 
						and dice cups required to play the first draft of the 
						rules. 
						 
						Although no longer used, this prototype has pride of 
						place in Bob Cordery's wargames room. | 
					
					
						
						The prototype proved the viability of the PORTABLE 
						WARGAME concept, and the next stage in its development 
						used a larger vinyl chessboard. 
						 
						This had the advantage of having larger grid squares - 
						which allowed more and/or larger figures to be placed in 
						each square - as well as having the capability of being 
						rolled up when not in use. 
						 
						It was also possible to temporarily 'fix' terrain items 
						to the chessboard using Copydex rubber glue. | 
						
						  | 
					
					
						
						  | 
						The terrain used was 
						made from thin cardboard (the river and the roads), 
						pieces of cork floor tile that was cut to size and 
						gently shaped (the hills), commercially available trees 
						(ready0made trees from Essex Miniatures), and houses 
						from a 'Village in a bag' set sold in various toy shops 
						and online. 
						 
						The figures used were very old Peter Laing 15mm-scale 
						Austrians and Prussians from the range of nineteenth 
						century figures that were on sale in the 1980s. | 
					
					
						
						Having proved that the rules worked and produced a 
						satisfactory wargame, the next stage in the development 
						of the PORTABLE WARGAME saw a change of historical 
						period (from Horse & Musket to Modern) ... and the 
						introduction of an even larger grid. 
						 
						The grid used was originally constructed for another 
						game, but the size of the grid squares (4" x 4"/10cm x 
						10cm) allowed the use of 20mm-scale figures and 
						vehicles. 
						 
						The changes required to make the rules suitable for the 
						later historical period were based upon ideas put 
						forward by Joseph Morschauser ... and worked very well 
						indeed.  | 
						
						  | 
					
					
						
						  | 
						Although the 
						original rules had been written for a square grid, many 
						wargamers own hexagonal wargames terrain, and the next 
						development saw experiments using hexed terrain. 
						 
						As Bob Cordery had a large quantity of reasonably 
						portable Heroscape™ terrain available, the first battles 
						using the hexed grid version of the rules utilised
				painted Heroscape™ terrain and the old 
						Peter Laing 15mm-scale Austrians and Prussians. 
						 
						These play-test battles proved that the rules would work 
						- with minor modifications - with both squared and hexed 
						grids. | 
					
					
						
						Having reached the stage where the Portable Wargame 
						seemed to be about as developed as it was likely to 
						become, Bob Cordery moved on to other things ... for a 
						while. 
						 
						During this break in development a small group of 
						enthusiasts were enjoying using the rules and eventually 
						they prevailed upon Bob Cordery to resume the 
						development of the Portable Wargame concept. 
						 
						The first new versions of the rules included some 
						much-needed changes that made it possible for Units to 
						become degraded by combat rather than being totally 
						destroyed as a result of a one-off fight with another 
						Unit. 
						 
						Players had also requested changes to the rules that 
						allowed grid were large than 8 x 8 to be used, and from 
						this was born the Big Board Portable Wargame.  | 
						
						  | 
					
					
						
						  | 
						
						The layout used for the Big Board 
						Portable Wargame rules proved very popular, and 
						in late 2012 Bob Cordery reformatted his existing MEMOIR 
						OF BATTLE AT SEA rules so that they were compatible with 
						them. He also renamed the rules and they became the 
						PORTABLE NAVAL WARGAME rules. |
