The minor battle was McClellan's only tactical offensive action against Richmond. His attack gained only at a cost of over 1,000 casualties on both sides and was not strong enough to derail the offensive planned by Robert E. Lee, which already had been set in motion. The next day, Lee seized the initiative by attacking at Beaver Dam Creek north of the Chickahominy River, near Mechanicsville, the first major battle of the Seven Days, and the beginning of a strategic retreat by the Union Army.Salmon, p. 98.
