Further Information
 
Angus George Gillman was a Major in the Royal Field Artillery who died on 29/04/1917 at the age of 34. He is buried at Ecoivres Military Cemetery, Mont-St Eloi. He was the son of William and Maud Gillman, of Portsmouth. In Kelly's 1912 Directory William Gillman is shown as a JP living at 47 Clarence Parade, Southsea. William and Maud Gillman paid for this memorial to their son in the form of a reredos and lancet window in the Cathedral which in 1920 was still St Thomas's Parish Church. The memorial was dedicated on 29th February 1920.
 
The installation of the various aspects of the memorial took place at the same time as some structural work was being carried out by the architect. During this operation original parts of the early church were uncovered including the lancet window which was incorporated into the memorial. The stained glass image in the window depicts Major Gillman as St George kneeling before Christ.
 
In the late 1920s William and Maud Gillman were asked to fund further modifications to the east end of the church which they appeared pleased to do.
 
It is not known when the reredos was removed and placed in store.
 
Major Gillman is one of 81 names to appear on the World War 1 Memorial outside the Cathedral and he is listed on the Guildhall Square Cenotaph.
