Bill Williams visited the USA on five occasions, the first two in the run up to D Day.
The RAOC already had good working relationships with the UK motor industry, but with so many supplies now coming from the US, new links had to be built and quickly.
In April and May 1943 Bill Williams had visited North Africa to learn at first hand the problems which faced Ordnance in the three opposed landings in North Africa, Sicily and Italy. The difficulties stemmed from the invading forces needing to be able to carry out immediate repairs to equipment in the field, under fire. This meant that the right spares had to be packed, that they must be in a size of box that can readily be carried or transported up a beach under fire, that the box can be stacked so as to be accessible, that they are clearly labelled with their contents and that the contents is preserved from damage from sea water or rough handling. Spares will not be handled with care.
Armed with this feedback from users he set out for a two month long trip to the United States, the purposes of which were to build relationships with the manufactures, to see for himself US war production, to stress the importance of spare parts and to explain his new proposals for the packing and preservation of stores. His PA prepared a full report of his visit and it is possible to read between the lines. The British were regarded as brave but possibly second class when compared to the much better organised and equipped US Army. Bill was, by his own admission, overawed by the US: New York was quite simply unlike anything he had ever seen. Nevertheless, he was not to be outdone and his tour showed a man genuinely interested in what he saw and keen to learn. Subsequent visits would see him giving very much as good as he got.
