The most dangerous bombs were those dropped from low altitudes, which were not activated until they had landed. These unexploded bombs buried themselves in cities and fields and remained dormant until their trembler contacts were disturbed—by a farmer’s stick, a car wheel’s nudge, the bounce of a tennis ball against the casing—and then they would explode.
Singh was moved by lorry with the other volunteers to the research department in Woolwich. This was a time when the casualty rate in bomb disposal units was appallingly high, considering how few unexploded bombs there were. In 1940, after France had fallen and Britain was in a state of siege, it got worse.
By August the blitz had begun, and in one month there were suddenly 2,500 unexploded bombs to be dealt with. Roads were closed, factories deserted. By September the number of live bombs had reached 3,700. One hundred new bomb squads were set up, but there was still no understanding of how the bombs worked. Life expectancy in these units was ten weeks.
In the car, driving down to Westbury, Singh had sat in front with Mr. Harts while Miss Morden rode in the back with Lord Suffolk. The khaki-painted Humber was famous. The mudguards were painted bright signal red—as all bomb disposal travel units were—and at night there was a blue filter over the left sidelight. Two days earlier a man walking near the famous chalk horse on the Downs had been blown up. When engineers arrived at the site they discovered that another bomb had landed in the middle of the historic location—in the stomach of the giant white horse of Westbury carved into the rolling chalk hills in 1778. Shortly after this event, all the chalk horses on the Downs—there were seven—had camouflage nets pegged down over them, not to protect them so much as stop them being obvious landmarks for bombing raids over England.
From the backseat Lord Suffolk chatted about the migration of robins from the war zones of Europe, the history of bomb disposal, Devon cream. He was introducing the customs of England to the young Sikh as if it was a recently discovered culture. In spite of being Lord Suffolk he lived in Devon, and until war broke out his passion was the study of
