In the case of Charles Whittemore it was decided that she would resume her role as an innocuous merchant ship in the hopes that she would become a target for U-boats.

Since no contact was made with the enemy, and N-5 broke loose during a storm, Charles Whittemore returned to New London on 9 September.

Continuing her service with the Atlantic Submarine Force, the Charles Whittemore carried submarine supplies, vital spare parts, and other cargo between New York, Newport, New London, Bermuda, and Charleston, S. C., until 14 May 1919 when she returned to New York from Hampton Roads to be sold.

[2][3][4] Charles Whittemore later was damaged by fire and a storm off Cape Cod on 11 January 1927, and abandoned at sea.
