SS Maréchal Joffre (1933)

Overview

SS Maréchal Joffre was a diesel-powered Messageries Maritimes passenger and mail liner built at La Ciotat for the Indian Ocean and Far East services. Launched in May 1931 and entering regular service in March 1933, she was the sister ship of Jean Laborde and belonged to the company's interwar generation of so-called “nautonaphtes”—large motor liners intended to replace older steam tonnage on long eastern routes.

Her wartime career was unusually international. After operating in Southeast Asia through 1941, she escaped Manila, reached Australia and then the United States, and entered U.S. Navy service as USS Rochambeau (AP-63). Converted for casualty evacuation and transport work, she served across the Pacific before returning to French control after the war. Rebuilt again for civilian service, she remained with Messageries Maritimes until 1960.

Key Facts

The Nautonaphte Generation

Messageries Maritimes used the term “nautonaphte” for its new diesel passenger ships, emphasizing the break with the company's earlier steam fleet. Maréchal Joffre and Jean Laborde formed a closely related pair designed initially for Indian Ocean work and later used extensively on the Far East route.

The type was smaller than the grander Félix Roussel, Georges Philippar, and Aramis trio, but shared the same interwar emphasis on diesel propulsion, long-range efficiency, and mixed passenger classes.

Indian Ocean and Far East Service

Maréchal Joffre first served the Indian Ocean route before being shifted increasingly toward Indochina and the Far East. She left Marseille on her first regular voyage in March 1933 and became part of the company's eastern network connecting France with ports across the Indian Ocean and Southeast Asia.

Her commercial role combined first-, second-, and third-class passengers with several hundred lower-fare travellers, reflecting the broad social range of Messageries Maritimes' eastern services.

The 1937 Modernization

In 1937 the ship was repainted white and substantially improved mechanically. Her diesel engines were supercharged, raising power from roughly 6,800 to 10,450 horsepower and increasing speed from about 16 to 19 knots.

Unlike sister Jean Laborde, which was lengthened and received a more visibly altered bow, Maréchal Joffre retained her original straight-stem form. The sisters therefore became easier to distinguish photographically after their respective rebuilds.

The 1939 Hong Kong Collision

On 30 March 1939 Maréchal Joffre was struck at Hong Kong by the P&O liner Canton. The damage was repairable locally and the French ship returned to service.

The incident belongs to the final months of normal interwar operation before the political and military environment of East Asia fundamentally changed the ship's role.

War in Southeast Asia

At Saigon in June 1940, Maréchal Joffre remained in Asian waters and continued regional commercial work rather than returning to occupied or Vichy-controlled metropolitan France. Contemporary British naval records show the ship among French vessels whose employment in Asian trade was being actively discussed.

By December 1941 the situation had become urgent. With Japan entering the war, the ship was at Manila and came under Free French control. She departed the Philippines and moved through Balikpapan toward Australia.

Darwin and Escape to the United States

The ship reached Darwin during the opening phase of the Japanese advance. She survived Japanese attack in the region without serious damage and continued southward to Australia.

From there she crossed the Pacific and arrived at San Francisco on 19 April 1942 carrying cargo that included wool and zircon sand. The following day the U.S. Maritime Commission took possession of the vessel and transferred her to the Navy.

USS Rochambeau (AP-63)

Commissioned on 27 April 1942, the former Maréchal Joffre became USS Rochambeau, hull number AP-63. She was rebuilt at Oakland for casualty evacuation and troop transport service.

The transformation was substantial but retained the underlying passenger-liner structure. Her civilian accommodation became useful for moving reinforcements outward and carrying wounded personnel back from the Pacific.

Casualty Evacuation in the Pacific

On her first U.S.-flag operation, Rochambeau carried replacements and reinforcements toward the Guadalcanal theatre, then embarked casualties at Nouméa, Suva, and Bora Bora for return to San Francisco.

She subsequently made repeated voyages between the U.S. West Coast and central and southwest Pacific bases. This work placed a French interwar liner directly inside the American logistical system sustaining the Pacific war.

Return to French Control

In March 1945 Rochambeau was decommissioned from U.S. Navy service and transferred for continued transport work. She returned to the French flag later that year and was formally restored to French control in 1946.

French authorities then used the ship for repatriation work involving civilians from Indochina and China before preparing her for a return to commercial passenger service.

The 1951 Rebuild

A major postwar reconstruction altered the ship's appearance yet again. The two square funnels were replaced by a single large oval funnel, and passenger accommodation was reorganized into first, tourist, and lower-fare categories.

The rebuilt ship therefore had three visually distinct identities: the original dark-hulled interwar liner, the white prewar Far East liner, and the single-funnel postwar passenger ship.

Final Years

Maréchal Joffre continued in Messageries Maritimes service through the 1950s, helping restore passenger links while newer postwar vessels gradually entered the fleet.

She was withdrawn on 19 January 1960 and sent to Osaka for demolition, ending a career that had stretched from interwar colonial passenger service through Free French and U.S. naval use and back into postwar civilian operation.

Why Maréchal Joffre Matters

Maréchal Joffre is particularly valuable because her history crosses several maritime systems without losing continuity of hull identity. She was a French commercial liner, an improvised wartime refugee from Southeast Asia, a U.S. Navy transport, a casualty-evacuation ship, a repatriation vessel, and once again a civilian liner.

Her career also broadens the Messageries Maritimes story beyond spectacular losses. This was a ship that survived repeated political and military upheaval and remained useful for nearly three decades.

Collecting Profile

Surviving material can appear under both Maréchal Joffre and USS Rochambeau. Messageries Maritimes postcards, brochures, passenger documents, U.S. Navy photographs, troopship records, and postwar publicity all belong to different phases of the same hull.

Dating is especially important because funnel configuration, hull colour, military paint, and name changed over time. A photograph that appears generic at first glance can often be assigned to a specific period through those visual clues.

Interpretive Notes

Do not confuse her with the later Maréchal Pétain / La Marseillaise: the names are similar but the ships were entirely different vessels.

USS Rochambeau was the same ship: the U.S. Navy did not merely charter a lookalike or sister ship; it commissioned the former Maréchal Joffre as AP-63.

The 1937 modernization changed performance more than dimensions: unlike Jean Laborde, Maréchal Joffre retained her original hull length and straight bow.
