and subsequently Japan (August)

Reservists called up in Paris and the branches. As France's leading British coal trader, the Maison Worms, had 21 branches in the country at the time that war was declared, plus branches in Algiers (Algeria), Pasajes (Spain), Cardiff, Newcastle and Great Grimsby (Great Britain), Port Said, Suez, Cairo and Alexandria (Egypt), as well as Buenos Aires (Argentine Republic). Its fleet comprised 18 steamships offering regular services between French ports and Great Britain, Belgium, Holland, Germany and Scandinavia. With the declaration of war, contracts for coal supplies in Port Said (including the contract with the Navy) immediately became null and void. The sharp increase in demand in Cardiff, given the local coal's suitability for powering warships, led to a crisis and created confusion. Intermittent requisition of vessels in the fleet depending on the needs of the national Administration. Cessation of operations on lines in the North Sea, with Germany and the Baltic (the "Listrac" and its crew blocked in Hamburg). The stocks of coal in Marseilles and Bordeaux requisitioned by the military equipment authorities.

The war of movement (August-September) becomes a trench war on a front extending
from Switzerland to the North Sea

While the requisitioned vessels were being used to carry raw materials for the Navy and public authorities and for troop supplies, the rest of the fleet continued to serve ports on the Atlantic and in the Channel to supply the civil population, providing back-up for the railways whose services were suffering from delays or disruptions. Being based in Britain, Worms & Cie played an active part in shipping British coal abroad, volumes increasing as a result in substantial proportions.

Volumes of British coal imported into France doubled following the occupation of the coal basin in the Pas-de-Calais and the halt of imports from Belgium and Germany: soaring prices exacerbated by port infrastructure incapable of receiving incoming consignments and shipping them on to their hinterland

Closure of the Bordeaux and Rouen line because of the slump in freight volumes.

Start of the air and submarine war. British blockade of German ports stepped up (January-March)

Retirement of Henri Goudchaux on health grounds. Disorganisation in trade exchanges because of the German blockade, the priority given to Admiralty ships interfering increasingly with coal traffic in Cardiff.

Dutch companies stopped shipping via the Suez Canal. Efforts to find a combined solution to enable the Navy to stock up on coal with the company in Port Said rather than from the British Admiralty. Loss of the "Léoville", sunk by a floating mine between Dieppe and Grimsby (19 January). Plans to establish monthly stocks of 8,000 tonnes of coal to cater to the Navy's needs in Port Said and ensure its handling operations. Deliveries to lighting companies and supply of gas coal in the Bayonne, Pau region, etc.  Delivery of the "Château-Latour" (March).

Organisation of the coal market by the French State: 22 April bill "on charging for and transporting coal on vessels flying the French flag" and Sembat-Runciman agreement (25 May) on the charges for freight transport and for British coal. Introduction of import and chartering licences. Establishment of a Coal Office to place orders for British coal with the British authorities and issue the corresponding authorisations

First reference to the Ateliers et Chantiers de la Seine-Maritime in written correspondence (November) and first purchases of land in Le Trait (December), a small town on the right bank of the River Seine upstream from Rouen, where these shipyards would be built. This initiative was taken at the request of the Government which was anticipating a shortage of vessels, with so many ships in the existing fleet being sunk by German submarines, and via its spokesman Anatole de Monzie, Under-Secretary of State for the Merchant Navy and Maritime Transport, requested three industrial and financial groups, one of them being Worms, to play a part in reconstructing the fleet and thus ensure French independence in the shipping sector.

Appointment of Hypolite Worms to the post of Assistant Treasurer of the Central Committee of French Shipowners. Rise in cost of living in Port Said.

Russian Revolution (March-October), United States enters the war (6 April)
first Battle of the Atlantic

In a request to further defer the call up of the Manager of Worms & Cie in Port Said, it was argued that in Egypt the company supplied the coal needed for vessels chartered by the State, the Suez Canal Company, the Messageries Maritimes, the Chargeurs Réunis, and numerous other French, British, Japanese and Dutch shipping companies, for which it was also the local shipping agent, that it ran the general agency of the "Shell" Group and, as such supplied the country with petroleum, fuel oil and petroleum spirit, and more particularly the French and British Navies and the Salonika base, that it also managed the oil concessions in the Red Sea (Anglo-Egyptian Oilfields) and the oil refinery in Suez, this latter being contracted to cater to all the Salonika base's petroleum spirit needs. Loss of the "Château-Yquem" (30 June), the "Saint-Émilion" (24 July), the "Sauternes" (5 August) and the "Thérèse-et-Marie" (9 August).

Agreement between Worms & Cie Bordeaux and the British Admiralty over handling operations. Transfer of freight operations (especially those for the Navy) to dedicated subsidiaries, given the growing scale of these activities, which had become too much for the port agencies to handle: establishment of the Compagnie Charbonnière des Appontements de Bassens & de Lagrange (near Bordeaux), specialising in the handling and transhipment of bulk goods and miscellaneous commodities in French and foreign ports (July). Stake taken in Basile Have & Cie (Rouen), when this general partnership was converted into a private limited company, renamed the Compagnie Charbonnière de Manutentions et de Transports (August). The Administration took complete control of the receipt of incoming goods in Dieppe and distribution of domestic coal in neighbouring provinces (August). One of the participants in forming the Société Commerciale du Canal de Tancarville, the purpose of which was to study and perform all the various works needed in the ports of Le Havre and the Seine Estuary (September). Ban on transfer of flags and on the sale of French ships abroad. Contract signed with the Navy for the carriage of 8,000 tonnes of coal per month from Wales to the port of Brest reduced to 6,000 tonnes given the large number of Worms vessels torpedoed or sunk by mines (November). Transhipment operations on behalf of the French Government in Port Said impeded by the branch's involvement in meeting the military and merchant needs of the port (December). Worms & Cie mandated by the Navy to make its organisation in all ports in the United Kingdom available and act as the Navy's general agent in taking over the steamships allotted to France by the Inter-Allied Committee without delay and managing them until they reverted to time charter (28 December).

Foundation of the Ateliers et Chantiers de la Seine-Maritime,
third department of the Maison Worms

Creation of the Chantiers du Trait in the heart of the countryside – in other words development of the industrial site (with 8 building berths, sheet metal, boiler making, mechanical engineering and carpentry shops, etc.) and transformation of the original village into a city with infrastructure, homes and shops, etc., to cater to expected population growth, an operation spearheaded by Georges Majoux.

with a view to supplying the French and Allied fleets disembarking in Syria and to contribute to economic development in the region: attempts to attract business among the clients of Prince Line Ltd and Ellerman Line.

Signature of an armistice between France and Germany (11 November),
the latter's capitulation signalling the end of the war

Despite the requisition of a number of its ships and the loss of 10 of its vessels, Worms & Cie was still able to maintain as regular as possible sailings between ports on the Atlantic and in the Channel, thereby playing a leading role in keeping industry and the civilian populations supplied with staple needs. It was during this period that that the "British Channel line" was created, a line linking Le Havre and Caen with Bristol, Swansea and Newport. In the wake of the general trend towards an increase in the exports of British coal, the volumes carried and sold in France and Egypt (especially in Le Havre and Port Said) rose in hitherto unprecedented proportions. For efforts in supplying warships "under very attractive conditions" for the State, Hypolite Worms was awarded the Légion d'honneur (12 February 1923). Foundation of the Agricultural and Forestry Consortium of Russia and Poland, under the auspices of the Ministry for Agriculture and Supply, with Hypolite Worms as a member of the first Board of Directors.
