This Day in History: 1968 Anti-Vietnam demo turns violent

More than 200 people have been arrested after thousands of demonstrators clashed in an anti-Vietnam war protest outside the United States embassy in London.
The St John Ambulance Brigade said it treated 86 people for injuries. Fifty were taken to hospital including up to 25 police officers. The trouble followed a big rally in Trafalgar square, when an estimated 10,000 demonstrated against American action in Vietnam and British support for the United States.
The mood at the rally was described as good humored. The violence broke out when the protesters marched to the US embassy in Grosvenor Square. The embassy was surrounded by hundreds of police. They stood shoulder to shoulder to cordon off the part of the square closest to the embassy.
Tensions rose as the crowd refused to back off and mounted officers rode at the demonstrators. The protesters broke through the police ranks onto the lawn of the embassy, tearing up the plastic fence and uprooting parts of a hedge.
During a protracted battle, stones, earth, firecrackers and smoke bombs were thrown. One officer was treated for a reported serious spinal injury, another for a neck injury.
One officer had his hat knocked off and was struck continuously on the back of the head with a stick from a banner as he clung, head down, to his horse’s neck. Earlier the actress Vanessa Redgrave was allowed to enter the embassy with three supporters to deliver a protest. She had been one of the speakers at the rally in Trafalgar Square.
Labor MP Peter Jackson, has said he will be tabling a private question for answer by the Home Secretary about what he called “police violence”. He told The Times newspaper: “I was particularly outraged by the violent use of police horses, who charged into the crowd even after they had cleared the street in front of the embassy.”

In context

There was another big anti-Vietnam war demonstration on 27 October 1968. An estimated 25,000 took part in the march and once again trouble flared outside the US embassy in Grosvenor Square. But security was very tight. There were 1,000 police outside the embassy and officers lined the streets of the march to prevent a repeat of the trouble in March. The last American troops left Vietnam on 29 March 1973. The following year there were frequent violations of the peace treaty.
In 1975, full-scale warfare resumed between North and South Vietnam -without American intervention. In 1976 the first elections were held to a National Assembly, finally reuniting North and South.
