When listening to Detail 1, any listener could make up the image of the Belgish king as a proud person who did not ask for help until the very last moment when there were no more alternatives. Hence, the aid he sought for could be provided by the British army that now had to undertake a greater risk. Hence, apart from a proud person, it can be inferred that Churchill's considers King Leopold a bad planner and others have to go and solve his problems instead.
When listening to Detail 2, King Leopold is ultimately described as a coward and a traitor who ran to make a deal with the enemy, leaving those who came to help him without protection. Apart from a bad ally, he has been unkind to the help and quite cynical.
