The Medal was presented by the Polish Consul on behalf of the Association of Warsaw Uprising Insurgents. The Consul commented "the distinction which I have the honour to present to you is a symbol of commemoration and gratitude and it is so important to remember and commemorate people like you." Mr Lambert was with the RAF's 148 Special Duties Squadron that flew from Brindisi in Southern Italy to drop supplies to the Warsaw Uprising insurgents as they fought to retain control of their city in August 1944. At that time, the extremely hazardous non-stop flights, largely over enemy territory, were amongst the longest ever recorded by the RAF and very few returned. In August 2014, Mr Lambert together with two of his fellow Halifax crew members attended commemorative ceremonies in Warsaw at the invitation of the city's President. Earlier that year, with the same remaining crew members Larry Toft and Jim McKenzie Leith, David visited the Yorkshire Air Museum to be reunited with a fully restored Handley Page Halifax. This visit also covered some filming of the three remaining crew as part of a documentary for Polish television.
