The Shiro-Sathrati Expeditionary Force (SSEF) was a major contingent of the Imperial Forces of Shireroth during the Sathrati Emergency, coordinated under the Department of MASS. This force was specifically established to execute the largest naval and logistical invasion in Shirerithian history, aimed at liberating the Emirate of Sathrati through Operation Thuylemans' Wave. The expedition was bolstered by the Imperial Shirerithian Air Forces, which provided critical air support. Prior to its deployment, the SSEF underwent an extensive period of preparation, involving the mobilization of hundreds of thousands of soldiers, the relocation of military equipment, and the expansion of key ports including Raynor Point, Lichport, Musika, and Solaris. The bulk of the professional troops came from the Departments of Gaudin, Confluence and Isen, while the Eastern Dominions heavily expanded the weapon programs and key industrial complexes to provide sufficient goods to the frontline.

Formation and Operations

The SSEF was activated in 1731 AN following the pivotal victory at Zy-Rodun, partly contributed to Shiro-Batavian Tribune (Mid Grade) Mark Konincksberg. By early 1733 AN, the force was meant to successfully execute landings and liberate the Isles of Mirioth, Amity, and Yardistan. The expeditionary force consisted of a mix of reservists and professional soldiers. The Dominions' economy was pushed to its limits by draconian measures to make the operation a success. The bulk of the industrial material came from the Dominions of Greater Kildare, where questionable working conditions and long hours combined with a population surplus made the opening and expansion of the factories possible.

Preparations and Mobilization

From late 1731 to 1733 AN, the focus was on rigorous preparations. This included the training of personnel and the establishment of a naval blockade designed to weaken resistance and disrupt communications among Sathrati rebels.

Economic Mobilization

The preparations for the invasion required unprecedented economic mobilization:

Shipyard Labour Force:

• Over 250,000 skilled shipbuilders and trades workers were employed.
• Approximately 10% of auxiliaries were drafted into shipyards.
• Tens of thousands of conscripted unskilled civilian laborers supplemented the workforce.
• Workers were reallocated from other manufacturing sectors.
• The production process operated on two 10-hour shift cycles to maintain round-the-clock production.

Raw Material Mobilization:

• Over 5 million tons of steel were required for hull construction, representing at least 25% of the annual steel output of a major industrial power.
• 15 million board-feet of lumber were used for hulls, decking, and installations, sourced from national forests and reserves.
• Large quantities of coal, piping, wiring, steam engines, and auxiliary components were also mobilized.

Production Facilities:

• Over 100 coastal shipyards in the Duchy of Modan and So-Sara operated at emergency capacity.
• New slipways, drydocks, and workshops were constructed within months.
• Rail networks were upgraded to transport material stocks to shipyards.
• Prefabricated components were moved from inland factories on a crash basis.

Logistics & Manpower:

• A workforce of over 400,000 needed to be fed and housed in shipyard towns.
• Whole sectors of the merchant marine were retasked for supply chain conveyancing.
• Tens of thousands of dockworkers, mechanics, and riggers were mobilized.
• A mass call-up of civilian mariners and naval reserves was initiated to crew the ships.

Management & Oversight:

• Centralized authority controlled design, costs, labor, and material flows.
• Production quotas were met through martial enforcement, utilizing forced and conscripted labor sources.
• Quality and safety protocols were often compromised due to the rushed timeframe.

The Auxiliary Armada

An auxiliary armada of unprecedented scale was assembled, combining requisitioned commercial vessels and scratch-built small craft. The armada comprised over 8,600 vessels with a total gross tonnage of nearly 10 million tons. The fleet included:

Vessel Type	Quantity	Gross Tonnage (each)	Personnel Carried	Stores/Cargo Carried
Gunboat-Barges	1,000	150 tons	50 troops	Light Artillery
Horse Transports	2,000	60 tons	-	30 horses
Small Landing Craft	2,000	20 tons	30 troops	Light Supplies
Artillery Barges	200	300 tons	30 crew	Heavy Artillery
Gunboats	100	400 tons	60 crew	Medium Artillery
Pioneer Ferries	1,000	1,500 tons	200 troops	30 Tanks/Vehicles
Marine Barges	630	500 tons	120 troops	6 Light Tanks
Assault Boats	3,000	20 tons	30 troops	Light Supplies
Artillery Lighters	250	150 tons	15 crew	Light Artillery
Troopships	200	7,500 tons	1,500 troops	-
Cargo/Supply Ships	130	3,000 tons	50 crew	3,000 tons stores
Hospital Ships	25	6,000 tons	500 medical staff	1,000 casualties
Auxiliaries/Lighters	70	100 tons	10 crew	100 tons supplies

This fleet could transport an initial assault force of over 450,000 troops, 2,000 horses, 1,200 armored vehicles/tanks, and 1,500 artillery pieces. The logistics included over 2.5 million tons of ammunition, construction materials, fuel, food, and other stores. Over 100 hospital ships were prepared to evacuate up to 25,000 casualties from the beachheads. Additionally, 1,550 gunboats, artillery barges, and coastal defense craft provided offshore fire support.

Strategic Planning and Operation Thuylemans' Wave

• See: Operation Thuylemans' Wave

The Shiro-Sathrati Expeditionary Force (SSEF) faced two possible scenarios for their campaign against the Emirate of Sathrati. The first scenario involved an island-hopping strategy, which was strategically favored due to its focus on concentrating material and deploying the best troops progressively. This approach was expected to methodically dismantle the rebel strongholds one by one.

The second scenario, which called for a simultaneous assault on the three main islands, was favored by the political elite. This strategy aimed for a quick and decisive victory to mitigate the emerging threat from the Benacian Union in the north. There were also concerns that a slower, more methodical approach would drive the rebels on the remaining islands to entrench themselves further, leading to even greater resistance.

Despite the strategic advantages of the gradual approach, it was ultimately not chosen. The political pressure for a swift victory led to the approval of the simultaneous assault. This plan, named Operation Thuyleman's Wave, was finally sanctioned and launched on 2.01.1733.

Strategic Air Campaign: Prelude to Operation Thuylemans' Wave

Two months prior to the full-scale invasion of Mirioth, Amity, and Yardistan, the Shirerithian Imperial Air Forces initiated an intense strategic air campaign designed to cripple the Sathrati's ability to resist the impending assault. This campaign, codenamed Operation Thunderbird, aimed to achieve air superiority, disrupt enemy logistics, and destroy critical infrastructure.

Legacy

The assembly of such an extensive invasion armada demonstrated the immense maritime resources of the Imperial Republic. This undertaking highlighted the sheer scale and complexity of the logistical efforts required for a successful island-hopping campaign against Sathrati. The SSEF's achievements underscored the strategic and operational prowess of Shireroth's military forces during this pivotal period.
