Dear WW: If you are suggesting the Trojan Horse was an example of camouflage, that seems to be stretching the term pretty far. Camel flagging may be older than Macbeth, but I don't remember mention of it. I'm not even sure why it was important for the numbers of besiegers to be concealed, except to be a hint the weird women had been deceitful.The options of the defenders were limited, they could not send for re-inforcements. The basic purpose of camouflage is to escape detection. but can be extended to deception. such as building phony targets for enemy airforce to bomb. The Trojan Horse has some similarity to that
