Factual error: Several union soldiers wading across the waist-deep river (and later climbing out of the river) are carrying the U.S. Springfield Rifle, Model 1903, which is a bolt-action, magazine-fed rifle (Note especially the soldier who climbs out of the river holding his rifle above his head.) instead of the historical accurate muzzle loading rifle. The Model 1903 was adopted by the US Army in 1903 and used in World Wars I and II, but not the American Civil War. For a picture of the Model 1903 Springfield Rifle, see: http://www.army.mil/cmh-pg/Museums/Showcase/Myer/Myer-4h.htm. (00:14:30)

The driver gets out to let Alec Guinness out of the van and they are now parked by a low wall with an open vista (probably one of the many bomb sites in London at the time) and no buildings.The next shot then shows the van outside the buildings again.
