The following day they visited Ypres, the Menin Gate and the British First World War cemetery at Tyne Cot. On 13th they explored Brussels, and later visited Waterloo, the Dutch border, Bruges and Knokke. The staff accompanying them included Mr Cyril Williams (Maths) and Mr George Jones (English), who is third from the right, in the back of the photograph, wearing a beret.
