Over the weekend of 6th/7th March 1943 a massive exercise took place when Home Guard units from Staffordshire and Worcestershire attacked the city from the south and west. The defence was mounted by Birmingham's own battalions.
This is a contemporary description from the April 1943 issue of a magazine entitled
"Defence the Home Guard Monthly”.
(On the same page there are details of organisational changes in the 8th Durham and of the results of a shooting competition. Also in the footnote there is brief mention of the hazards and frustrations involved in the type of exercise undertaken in Birmingham)
