84 years ago this month, Sunderland was entering some of the darkest days of its history.
The Second World War was under way and Wearside prepared by digging trenches, preparing air raid shelters, and drilling air raid wardens.
Mums were taught how to use respiratory masks on babies and children had their evacuation kits checked.
It's all here in these Sunderland Echo archive photos.
