WHEN the bombs rained down and houses were reduced to piles of rubble, the familiar figure of the milkman picking his way along the street, jaunty cap on his head, was an immensely reassuring sight.

Sometimes, he would place a pint on the front step of a house, where the only part of the building that had survived was the doorstep itself.

He knew neighbours would find where the occupants were sheltering and make sure they got their milk.

Often the ‘milkman’ would actually be a woman, or a young boy, or a man too old for active service, because the regular roundsman had been called up. Many of those roundsmen never came home.

Britain’s Wartime Milkmen is a new book, packed with photographs and anecdotes, charting how our milkmen played a key role in the nation’s morale through the Great War and into the Second World War.

There are a number of Ealing photographs in the book, dating from the Great War, of letters from Cotching Cain & Skinner to customers and of an Ealing milkman, Ray Rookes, who served in both wars.

It also shows how the industry itself went through many changes: from three deliveries a day made by ‘milk pram’, a heavy handcart containing large churns from which the milkman measured out milk for customers, to the introduction of bottled milk delivered by horse-drawn carts - and finally to the electric milk float.

Some of these changes were the result of advances in technology, but most – including the disappearance of small dairies and the advent of ‘co-operatives’ – were a product of war.

Milkmen became part of popular culture over this period, and a number went on to find fame in other professions, including comedian Benny Hill and actor Sean Connery.

The book includes profiles of six milkmen including Ray Rookes, who served in both wars but still managed to walk 150,000 miles on his rounds during his 50-year career as a milkman.

The author, Tom Phelps, spent more than 30 years in the dairy industry working for Unigate.

Many of the photographs in this book have come from his own collection and many are being published for the first time.

Britain’s Wartime Milkmen is a large-format paperback of 88 pages, with more than 100 photographs.

It will be published by Chaplin Books on March 5 at £9.99 and will be available from all good bookshops and internet retailers, as well as direct from the publishers (www.chaplinbooks.com).
