This was discussed shortly in: A Study of History by Arnold Toynbee

Another anecdote that speaks to the sentiment of the beginning of the war is Britain’s initial deployment of troops. The troops were literally marching towards Germany with music and percussionists that was supposed to motivate the troops and strike fear into the enemy. I imagine an army like you would see in Game of thrones (walking from point A to point B and making camp in between). Germany used their planes and promptly dispatched the British troops which suffered devastating losses. After this event Britain changed their tactics and took the war seriously.

(This event may have been WW2 which would make the story even more ridiculous).
