Lord Nelson is on his flagship, HMS Victory, and the lookout shouts “Spanish Armada on the Port bow”, Nelson shouts for his cabin boy and says “go to my cabin and bring me my three cornered hat, my telescope and my red coat”.
After a minute or so, the boy comes with the requested items and gives them to Nelson. As he hands them over he says to Nelson “I know why you want your hat and telescope sir, but why do you want your red coat?”
Nelson replies “it’s for camoflage, if I’m wounded in battle, the men will carry on fighting because they will be unable to see my blood because of the red coat that I wear, and because they’ll not know that I’m injured, we may be able to defeat the Spanish”
The Royal Navy, due to Lord Nelson see off the Spanish Armada.
A couple of days later the lookout shouts “Spanish fleet on the Port bow.” Nelson looks and thinks ‘oh shit’ he shouts for his cabin boy and says to him ” bring me my three cornered hat, my telescope and my brown corduroy trousers.”
