Back in 2008 the word cartocacoethes was first used on this blog to describe “a mania, uncontrollable urge, compulsion or itch to see maps everywhere.”

Counter cartocacoethes can be applied in the world of espionage allowing spies to sneak intelligence out of hostile territories – making maps that don’t look like maps.

Stained-glass windows, butterfiles, leaves, moth heads…

In making the drawings of fortified positions after ascertaining their plans, it was the work of the spy so to disguise them that their true character would not be recognized in the event of his capture by military authorities in the country where he was operating.

The plans of a fortification were first drawn in a regular manner and then disguised. In one case this was done by sketching ostensibly a stained-glass window. To the casual observer the drawing would bear no indication of its importance, but to the spy it was a carefully executed map of a military stronghold.

In another case the spy chose an ivy leaf as a pattern, the veins being drawn to represent the outline of the fortified position; the shading marking the ground sheltered from fire, and heavy spots, resembling worm-eaten holes, the positions of the large guns.

Chemical smoke puffs represent exploding shells…

smoking_map_pg_may_1927

Surveyed through field glasses that make it appear miles away, a novel war map at Princeton University makes artillery practice realistic to students of the Princeton unit of the Reserve Officers Training Corps.

…Each student takes his turn at directing the miniature “barrage.” The ingenious map is operated by the instructor, who follows the student’s data and commands to fire. A small adjoining map is criss-crossed with lines showing where shells with various ranges would strike. Over this key chart moves a lever which, placed at the spot where the student’s shot would fall, swings a glass nozzle to a corresponding position on the large map; at the student’s word “fire” a puff of artificial smoke is released.
