Use of the Jolly Roger by submarines successful patrol: it would be hoisted as the submarine passed the boom net, lowered at sunset, and could not be flown again until another successful patrol had occurred. The Jolly Roger could also be flown on the day a submarine returned to the UK from a successful overseas deployment. Although some sources claim that "all" British submarines used the flag, the practice was not taken up by those submarine commanders who saw it as boastful and potentially inaccurate, as sinkings could not always be confirmed. Flying the Jolly Roger continued in the late 20th century and on into the 21st.
