In Grangetown, the Hollyman Brothers bakery was hit by a parachute mine and 32 people who were using the basement as a shelter were killed.
The raid of 29 April 1941 did not have the usual precursory flares or incendiaries and instead four land mines, probably intended for the Civic Centre, were parachuted without warning soon after the siren sounded.
This included ten members of the Palmer family who had taken cover in the Anderson Shelter in their back garden.
