Operation Bathtub II
Operational Group A
General Donovan, present in Algiers, assigns Lieutenant Colonel Serge Obolensky to lead this mission. The primary objectives are to make contact with General Basso of the Italian Army in Sardinia, encourage him to confront evacuating German forces, and seek approval for deploying Operational Group units in the area.

Upon their arrival by parachute, Obolensky and his team, including First Lieutenant Michael Formichelli and radio operators Lieutenant James Russell and Sergeant William Sherwood, set out to execute their plan. They successfully make contact with the Italian Air Force at Decimomannu Airport and are escorted to General Basso’s headquarters. Despite presenting their case, General Basso is reluctant to involve American special units in the operation.

Brigadier General Theodore Roosevelt Jr. later arrives to support the mission, bringing additional Operational Group officers to aid in diplomatic efforts and information gathering. Under Roosevelt’s guidance and with Obolensky as his Executive Officer, they conduct extensive surveys of Sardinian military and civilian infrastructure. Their findings lead to the deployment of various Allied support missions on the island.

By October 6th, 1943, leadership of the Allied Forces in Sardinia transitions to Brigadier Boulnois. Following this, General Roosevelt and Colonel Obolensky, along with their team, return to Algiers, concluding this phase of the mission.
