Here is the start of the timeline for the Taurian Initiative setting. More will follow later.
Timeline
July 9th 2571 SL is formed
Fall 2572 – United Triumph exercises conducted by SLDF.
2572 – SL begans trying to entice the Periphery states to join the SL
Dec 14th, 2572 – Santiago Massacre
Feb 19th, 2573 – A Taurian warship squadron strays into the Malagrotta System due to a navigation error. The local FS forces overreact and send a distress call for aid. The AFFS deploys a 10 ship flotilla to the system and destroys or captures most of the TDF squadron. Gisela Cadenas is assigned to the TCS Anaheim and is killed during this action.
March 2573 – SL imposes sanctions on the Periphery States.
April 2573 – David Santos is appointed commander of the Concordat Navy's 5th Fleet. The 5th Fleet is responsible for large portions of the Concordat/Federation border. Marshal Santos begins developing a series of contingency plans for scenarios involving hostilities with the SLDF and AFFS.
Tensions between the Inner Sphere powers and the Concordat increase in the wake of the Malagrotta Crisis.
April 2573- In response to the increasing tensions and the Malagrotta Crisis, TC quadruples Warship and military dropship production. The Concordat also dramatically increases production of aerospace fighters.
March 14, 2574- Mitchell Calderon becomes Protector following the death of his mother. The Concordat begins a massive military build up – as a result TC will double it's military and place strong militias on nearly every world over the next few years.
May 2574 During a visit to Taurus Marshal David Santos has a chance encounter with the Protector at TDF HQ. When questioned about what he needs to defend the border against threats from the SL and the FS, Marshal Santos proposes 2 new types of ships- the Star Runner class Scout Ship and the Armageddon Class Missile Cruiser. He also recommends the establishment of several forward operating bases for the Concordat Navy, which will reduce the need for ships to return to the Hyades Cluster for major repairs and resupply. As a result of this meeting, Taurus Shipyards is awarded a contract to develop the Armageddon, while Illuishin Shipyards is awarded a contract to begin developing the Star Runner. Designers from both shipyards work with Marshal Santos to develop the specifications for the new ships. The Protector also authorizes the construction of new Fleet bases in the Pleiades Cluster, the Badlands Cluster and the Anaheim System.
January 2, 2575 – SL issues the Pollux Proclamation
January 25th, 2575- In response to the Pollux Proclamation Protector Calderon declares a national emergency and requires all citizens to provide 4 years of national service.
March 1, 2575 – periphery states reject the Pollux Proclamation.
March 2576 David Santos is recalled to Taurus to plan and implement Case Amber.
July 2576- First Star Runner Class Scout ship is launched from Illiushin Shipyards. The design also enters production at the Horsham. The ships are coming off the building slips at a rate of 6 ships per year.
Sept/Oct 2577 – The Concordat Navy launches Case Amber. After luring the AFFS Navy deep into the Concordat, the Taurians launch a strike against the staging area of Panpour, destroying 9 warships and capturing 3 at the cost of a single corvette. They then ambush the AFFS fleet in the Tentativa system, destroying 28 AFFS warships and captures 11 others at the cost of 2 ships. During the operation numerous transports and supply ships are captured.
April 30th, 2578 – SL declares war on TC.
May 15th, 2578 – SLDF I Corps (1st & 2nd Divisions) invades Ridgebrook. During the invasion 4 TC warships are lost, while 3 of the SLDF's warships are destroyed. The SLDF also loses 10 dropships that are carrying over a regiment of troops. TDF forces hole up in mountain fortress outside the capital city and hold off SLDF troops with artillery and conventional forces.
May 2578 – SLDF III Corps (9th Division) invades Keuterville . There are no major naval actions in the system. TDF units on planet conduct a guerrilla warfare campaign. The SLDF suffers heavy losses with minimal results.
May 2578- SLDF VI Corps (16th Div) occupies Malagrotta system against no Taurian resistance.
July 2578 – SLDF VI Corps invades Csomad (17th Royal) and Armington (18th Div). The defenders on both worlds are easily overwhelmed, but on Armington the survivors manage to establish an effective guerrilla campaign, tying down the SLDF troopers.
August 2578 – An AFFS & SLDF naval task forces invade the Tentativa system. Tentativa is defended by a strong planetary defense flotilla supplemented by a roving warship patrol. The SLDF & AFFS Task Forces time their arrival in system to try and ambush the Taurian warship patrol. The 2 sides fight a long range battle as they head towards Tentativa. Unknown to the SLDF forces, the first operational Star Runner scout ship was assigned to the system. As soon as the invaders arrived at the Tentativa jump points, the Star Runner jumped to the Pierce system where the Taurian 5th Fleet was waiting. Provided with the heading and speed of the SLDF & AFFS Task Forces, the Taurian reinforcements jumped into a transient point near the planet, arriving mere moments after the Taurian fleet had halted it's retreat towards Tentative and engaged the attackers. Out flanked and out numbered, the SLDF & AFFS fleets took heavy losses before they were able to break off and retreat from the system.
Sept 2578 – Csomad is secured by the SLDF. Ridgebrook secured by the SLDF.
Sept 2578 – Following the stunning success of the Concordat Navy in the early days of the war, David Santos is promoted to command of the Concordat Navy and is a key advisor of the Protector. He is given free reign to run naval operations as he sees fit. Having proven the Star Runner concept during the 2nd battle of Tentativa, the Concordat orders increased production of the vessels. Marshal Santos also orders changes to the Navy training programs, placing increased emphasis on navigation skills, especially the use of transient points.
October 2578 – The first Armageddon Class Missile Cruiser enters service. Produced only in the Hyades Cluster the production rate is 2 ships per year.
October 2578 – Marshal Santos unveils Case Black, an audacious plan to take the war to the SLDF and FS. The plan calls for using the AFFS Warships captured at Tentativa and Panpour to strike into the FS.
October 2578 – Under pressure to produce results, General Wexworth launches several new operations. I Corps (1st & 3rd Divisions) drives on from Ridgebrook to Wrentham. While this move was not totally unexpected by the TDF, they did not provide any warships to defend the system. TDF ground forces were quickly defeated but inflict heavy losses on the SLDF.
October 2578 – The SLDF IV Corps (12th Division) invades Anaheim. Much to their surprise the system is home to a major TDF base hidden in the system's asteroid belt. 3 Concordat Warship Squadrons are in system as are a huge number of aerospace fighters and gunships. The TC warships make their presence known, drawing the attention of the SLDF warships, the majority of which head for the asteroid belt, while the SLDF transports head for the planet. Just before the transports make orbit, 1 of the Concordat squadrons conducts an in system jump to a transient point near the planet. Deploying large numbers of fighters and gunships, the squadron destroys many of the transports. The remaining ships are disorganized and upon landing their troops are easily overwhelmed by the local defenders. The SLDF warships, engage the TDF forces in the asteroid belt. Using their superior mobility and numbers, the TDF forces inflict heavy losses on the SLDF warships, chasing them back to the zenith point, where they retreat from the system.
November 2578 – The Concordat Navy launches Case Black. Intended to take the war to the SLDF, the attack involves 2 seperate operations. Rather then rely of Taurian warships, the plan calls for the use of the 14 AFFS vessels that were captured during Case Amber. One strike force, built around a captured New Syrtis class Carrier and 6 other ships, launches an audacious attack against the major AFFS command center and staging area at New Syrtis. Using AFFS transponder codes, the ships sneak into the system, where they launch a massive attack against the shipping and shipyards in the system. Caught by surprise, the SLDF loses several warships in the opening attack. Using marines, several ships are boarded and captured, while the shipyards in the system were destroyed using nukes. Fighting a running battle until their jump cores can be recharged, the Taurians lose 4 ships before they can make their escape. This is offset by the capture of 3 jumpships and 2 corvettes by Taurian Marines.
Meanwhile the other Taurian Strike force, launching from Weippe, hits Songgang, As Samik, Basantapur, Birmensdorf, June and Malagrotta before jumping into the Armington system. In each system, the Taurians destroyed any jumpships and dropships that they could not capture and stayed only long enough to recharge their jump cores. The only major encounter was in the Songgang system, where the SLDF's 11th Royal Division was based. The only warships in the system was a single squadron, which was quickly overwhelmed, with 3 ships destroyed and 1 captured. In the Armington System, the squadron swept aside the few naval vessels in the system and landed reinforcements on planet. The SLDF's 18th Division is force back on the defensive.
November 2578- SLDF VI Corps 16th division invades Estuan- small naval battle- TDF loses 1 corvette and 2 assault dropships. Major battles last 3 weeks, then a guerrilla campaign begins.
November 2578- SLDF replaces General Yulan on Keuterville with General Jamand a former CCAF special forces soldier. The SLDF begins a guerrilla campaign against the Taurian defenders.
December 2578, TDF deploys 2nd fleet to Armington in anticipation of SLDF reinforcements. When the SLDF ships arrived in system they are ambushed by the Taurians and suffer heavy losses. The ground campaign begins to turn in favor of the TDF.
2579 – This year sees a lull in the campaign. General Wexworth focuses his efforts on consolidating the gains he has already made and tracking down the Taurian fleet, which has been causing him so many problems. Short on supplies and replacements, it is difficult for the SLDF to rebuild damaged commands. Further complicating issues is the damage suffered by the navy- the warship fleet is spread thin trying to protect convoys moving into the Concordat and following Case Black they are also forced to defend numerous worlds along the FS border as the AFFS fleet is for all intents and purposes, non-existant. The major effort by the SLDF during this year is an effort to reoccupy Armington. Rather then provide the SLDF with a fixed target, the Taurian Navy takes to maintaining roving patrols of the system and relying on a Star Runner to monitor the situation in the system and provide intelligence. Both sides begin to lose numerous warships during the various engagements that occur in the system.
2579- The TC takes advantage of the lull in the war- warship production is further increased with the opening of new building slips at existing ship yards and construction of a new shipyard in the New Vandenberg System. The TDF also raises a number of new armor and mech formations. Efforts are also made to reinforce guerrilla forces on SLDF occupied worlds. A number of old jumpships that are barely serviceable are outfitted for automated operations. Loaded with dropships filled with troops and supplies, the ships are brought to within 1 jump of their target by a small Navy crew. The jump coordinates for the final jump are loaded into the computer and the ship is set on automatic control. Using pirate points, the ships arrive in the occupied system and detach their dropships which make a high speed run to the planet. While some of the dropships were destroyed by the SLDF, the majority made it safely to the planet. The jumpship were rigged with nukes and proximity sensors, when SLDF forces approached the ships the nukes detonated taking as many enemies with them as possible. These ships are used to re-supply the resistance on Csomad, Keuterville, Ridgebrook Estuan and Wrentham.
During this time, the TDF Navy continues to conduct numerous raids against shipping along the FS border. Typically operating in small squadrons, they not only destroyed numerous transports, but they also managed to hit several supply centers. Both sides suffered some warship losses, but the TDF warships largely avoiding attack SLDF warships unless they had numerical superiority. Realizing that the SLDF would eventually resume their attack, the Navy conducted numerous recon operations, scouting systems along the border for signs of SLDF troop convoys. After noting numerous troop carriers in the Taygeta, Sanurcha and Mandaree systems, TDF Intelligence assumed the next target would be the valuable Pleiades Cluster.
