The team tackles the conditions faced by the British farmers in late 1940, when Britain's cities were heavily bombed by the Nazis.

The Blitz resulted in one of the biggest mass movements of people in British history as three million city dwellers fled to the countryside. To make outbuildings habitable as refugee shelters, Alex and Peter resort to the age-old craft of making tiles by hand - which means camping out for two days and nights in freezing cold to tend the tile-making kiln. They are visited by a 94-year-old conscientious objector who was conscripted as a farm labourer because he refused to fight on religious grounds.

Ruth gets involved in the work of the Royal Observer Corps, who often enlisted farmers in the work of spotting enemy planes. Alex and Peter also learn how to set up 'decoy fires' to lure German bombers off target, a project known as Operation Starfish.

With December approaching, the team look forward to celebrating Christmas 1940-style. People were understandably eager to put the horrors of war behind them - if only for a day - but this was the first Christmas under rationing and compromises had to be made. Alex looks at government solutions to the national 'toy shortage', whilst Peter discovers that soap had become the nation's favourite Christmas gift. With turkeys few and far between, Ruth cooks up an alternative - known as 'mock turkey' or 'murkey' - made from apples, onion and a dash of sausage meat, with a pair of parsnips for legs.

The Wartime Farm team tackles the conditions faced by British farmers in 1942, when Hitler's U-boats continued to attack British ships, slashing imports and inflicting massive shortages on the country.

Ruth finds out how Britain coped with shortages of the wood vital for the war effort in the building of aircraft, ships and rifles, as well as pit props for crucial coal mining. With her daughter Eve, she travels to the New Forest and discovers how women known as 'Lumber Jills' were drafted in to fell trees in the Women's Timber Corps.

Meanwhile, Peter and Alex face up to the wartime petrol crisis. Peter embarks on an ambitious plan to convert a 1930s ambulance to run on coal gas. Alex experiences the conditions faced by the Bevin Boys - conscripts who were sent to coal mines instead of the armed forces because the need for coal was so great. Having converted the ambulance and collected the coal to run it, Peter faces the question: will it work?

Also in this episode, the boys revert to a Victorian solution to the shortage of animal feed - using traditional horsepower to operate a root slicer - whilst Ruth sets up an Emergency Feeding Centre. Subsidized by the government to provide cheap food off ration for air raid victims, these 'British Restaurants', as Churchill dubbed them, quickly caught on. Eating out had traditionally been the preserve of the upper class and most ordinary people had never eaten in public before - many even felt embarrassed at the prospect. The 'British Restaurants', envisaged as a short-term response to food shortages, made a lasting change to the nation - introducing the concept of high street dining for the masses.
