Listen again to Heart of Oak.
Heart of Oak is a propaganda song written to try to persuade people to join the Royal Navy. It was the old official March Song of the Navy in 1760.
Each of the verses talks about some of the jobs that you would do in the Navy, including fighting enemies even if it means destroying their ships and letting them drown.
Nowadays, the Navy is also involved in rescuing people.
Write at least one verse of the song that is to do with rescuing people at see.
