The London conference of 23 April 1949 only permitted some less far-reaching border modifications. At 12 noon that day, Dutch troops moved to occupy an area of 69 km2 (17,000 acres), the largest parts of which were Elten (near Emmerich am Rhein) and Selfkant. Many other small border corrections were executed, mostly in the vicinity of Arnhem and Dinxperlo.
