Overview: Today we're pulling up at Osterley Park in Middlesex, the site of the first Home Guard training school, to look back to the Second World War and a time when millions of ordinary men were prepared to die for our country as Home Guard recruits. Robert Brown will come face to face with his father as a Home Guard Company Commander. Dad's Army creator, Jimmy Perry will tell us why he signed up to the Home Guard. And Ken Chambers will share with us his own extraordinary stories from his time in the Home Guard, some of which could have been taken straight from Dad's Army.
