The Van Alen hospital was the smallest of the donative hospitals and was formed by a Mr Van Alen, an American Citizen. He agreed to provide all necessary equipment and transport for the small hospital at its own expense. The War Office agreed to transport it to South Africa and return it when it was no longer required. The hospital operated in the area near Kimberley.
Captain E Powell RAMC was in charge of the hospital.
There is a mention in The Times History, Vol 6, p 533:
An American citizen, Mr. Van Alen, equipped Mr. Van and took out a section of a field hospital, which went to Kimberley in March, 1900, and accompanied Lord Methuen in his operations north and west of that town in April. It was subsequently handed over to the military authorities at Paardekraal in July, 1900.
There are two mentions in despatches:

2. Van Alen Hospital - Mr Van Alen.
