I went around my mothers house and asked her about WW2 sirens. The following is her recollection of those years, she was nearly 7 years old at the time.
She remembers laying across a small bunk at the back of the shelter. Laying there with blankets over her head and hands over her ears & wearing a gasmask, trying to block out the noise of the sirens & the bombs. Gran patting her back and saying `none of the jerry bombs had there name on'.
She then heard the " all clear" frightened encase they had no house left. During "the battle of Britain" my mother had to stay down there every night. They eventually came out, only to discover that the next street had a direct hit & her 3 year old cousin being dug out of the rubble dead.
Those were my Mums recollection of the Sirens.
