He had expected a hundred or so police. In fact, there were thousands.

They stood lining the pavements, waited in dozens of parked buses, and sat astride huge horses in remarkably neat rows. Only a narrow gap was left for people who wanted to walk along the streets. There were more police than Fascists.

From inside one of the buses, a uniformed constable gave him the Hitler salute.

Lloyd was dismayed. If all these policemen sided with the Fascists, how could the counter-demonstrators resist them?

This was worse than a Fascist march: it was a Fascist march with police authority. What kind of message did that send to the Jews of the East End?

In Mansell Street he saw a beat policeman he knew, Henry Clark. ‘Hello, Nobby,’ he said. For some reason all Clarks were called Nobby. ‘A copper just gave me the Hitler salute.’

‘They’re not from round here,’ Nobby said quietly, as if revealing a confidence. ‘They don’t live with Jews like I do. I tell them Jews are the same as everyone else, mostly decent law-abiding people, a few villains and troublemakers. But they don’t believe me.’

‘All the same . . . the Hitler salute?’

‘Might have been a joke.’

Lloyd did not think so.

He left Nobby and moved on. The police were forming cordons where the side streets entered the area around Gardiner’s Corner, he saw.

He went into a pub with a phone – he had scouted all the available telephones the day before – and told Bernie there were at least five thousand policemen in the neighbourhood. ‘We can’t resist that many coppers,’ he said gloomily.

‘Don’t be so sure,’ Bernie said. ‘Have a look at Gardiner’s Corner.’

Lloyd found a way around the police cordon and joined the counter-demonstration. It was not until he got into the middle of the street outside Gardiner’s that he could appreciate the full extent of the crowd.

It was the largest gathering of people he had ever seen.

The five-way junction was jammed, but that was the least of it. The crowd stretched east along Whitechapel High Street as far as the eye could see. Commercial Road, which ran south-east, was also crammed. Leman Street, where the police station stood, was impenetrable.

There must be a hundred thousand people here, Lloyd thought. He wanted to throw his hat in the air and cheer. East Enders had come out in force to repel the Fascists. There could be no doubt about their feelings now.

In the middle of the junction stood a stationary tram, abandoned by its driver and passengers.

Nothing could pass through this crowd, Lloyd realized with mounting optimism.

He saw his neighbour Sean Dolan climb a lamp post and fix a red flag to its top. The Jewish Lads’ Brigade brass band was playing – probably without the knowledge of the respectable conservative organizers of the club. A police aircraft flew overhead, an autogyro of some kind, Lloyd thought.

Near the windows of Gardiner’s he ran into his sister Millie and her friend, Naomi Avery. He did not want Millie to become involved in any rough stuff: the thought chilled his heart. ‘Does Dad know you’ve come?’ he said in a tone of reproof.
