Sixty-four years ago today, on March 4, 1945, an 18-year-old Princess Elizabeth joined the British Army as a mechanic and truck driver.
SooToday.com is pleased to commemorate this anniversary with From Princess to Queen, an hour-long 1996 BBC documentary full of archival photographs, home movies and newsreel footage showing the transformation of "Lilibet" into Queen Elizabeth II.
Princess Elizabeth's brief lorry-driving and lorry-fixing career can be seen at 4:30 in Part 4 below.
