During a contentious period in February 1792, Andrew Ellicott, who had been conducting the original boundary survey of the future District of Columbia (see: Boundary Stones (District of Columbia)) and the survey of the "Federal City" under the direction of the Commissioners, informed the Commissioners that L'Enfant had not been able to have the city plan engraved and had refused to provide him with the original plan (of which L'Enfant had prepared several versions). Ellicott, with the aid of his brother, Benjamin Ellicott, then revised the plan, despite L'Enfant's protests. Ellicott's revisions, which included the straightening of the longer avenues and the removal of L'Enfant's Square No. 15, created changes to the city's layout (See: Randolph Square).
