The latest edition of a book about Walter Tull is to be launched this weekend.

Author and biographer Phil Vasili will be at Folkestone Museum from 11am to 1pm on Saturday to give a talk and sign copies of the updated edition of his book Walter Tull 1888-1918, Footballer and Officer.

Tull, who was killed in action 100 years ago last month, was one of the first black professional footballers in Britain and the first black British Army officer, being commissioned as a Second Lieutenant even though the rules said officers had to be of “pure European descent.”

His life has been the subject of a television documentary and drama, and there are plans to make a film about him.

It was largely due to Mr Vasili's research that Tull's story, and his heroic actions during the First World War, came to light. He was recommended for the Military Cross, but never received it.

Calls have been made to try to persuade the government to make the award posthumously, so far without success.

Walter's father, Daniel, was the son of a slave from Barbados, came to England and settled in Folkestone where he met and married Alice Palmer, who was born in Dover. Walter went to North Board School, Mundella Primary School, in Black Bull Road, Folkestone.

Folkestone Museum, in Guildhall Street, plans to explore Tull's extraordinary life in an exhibition this autumn.

It will have documents and photographs from the Tull family archive and Action for Children, who hold the archives of the children’s home where Walter and his brother Edward lived following the death of both their parents. Contributions also come from the National Army Museum and other partners.

A number of Tull's relatives attended events in Northampton , where Walter played football, to mark the centenary of Walter's death on March 25, 1918.

. A memorial ceremony was held at Tull's statue at the Guildhall, followed by a series of talks.

The next day, the actual centenary date, a blue plaque was unveiled at nearby Rushden where Tull lived, and another service was held at All Saints Church in Northampton.

Among those taking part were Ed and Duncan Finlayson and Pat Justad from Scotland. They are the grandchildren of Tull's brother Edward, so Walter was their grand uncle.

Three relatives from the Palmer side of the family met for the first time,

These were ex-Mercury reporter Graham Tutthill from Dover who attended the weekend's events with his wife Jill.

The other two were Elizabeth Coombe who used to live in Dover, went to school in Folkestone and now lives near Northampton, and Mark Bird who also lives near Northampton.
