Operations Ambush and Riposte
A Capellan Confederation counter-attack launched during fourth wave of Operation Rat, Operation Riposte was intended to destroy under-defended supply depots on six worlds vital to the Federated Suns continued involvement in the Fourth Succession War. Unbeknownst to the Capellans however, the supposed Achilles Heel they were targeting as part of Riposte was in fact false intelligence designed to convince them to strike as part of Operation Ambush.
As the Armed Forces of the Federated Suns launched the fourth wave of Operation Rat, the Davion troops quickly began to realise that they were not encountering any resistance from front-line Capellan Confederation Armed Forces units. In response to Rat's third wave, Chancellor Maximilian Liao had ordered them withdrawn to prevent them from being cut-off from the rest of the Confederation, but also to use them in a ambitious scheme to cripple the Davion offensive under the code name of Operation Riposte.  
Information supplied by traitorous Capellan March Duke Michael Hasek-Davion supposedly revealed to the Chancellor that all the supplies for the AFFS forces involved in the invasion moved through only six worlds, which had now been stripped of their BattleMech garrisons as the invasion ceaselessly drove deeper into the Confederation. The loss of these depots would cripple the Davion offensive in the Confederation, and with luck the Draconis Combine's own drive into the Terran Corridor would force the AFFS to grind to a halt, buying the CCAF vital months to rest, regroup and counter-attack. Desperate to regain the initiative and with the Maskirovka verifying Hasek-Davion's intelligence as seemingly accurate, the Chancellor committed among his last remaining front-line units and reserve DropShips and JumpShips to the task, some six BattleMech regiments with twice as many support units. An additional seventh world would also be targeted as part of Riposte after Capellan agents learned of compelling intel pointing to an New Avalon Institute of Science laboratory on Axton on the brink of breakthrough in myomer strength. Though some within the Confederation doubted the leaked information, such as Pavel Ridzik, the Chancellor's trust in Hasek-Davion was so total he refused to consider any other option. 
Unfortunately for the Capellan's, First Prince Hanse Davion and the MIIO had been aware of Hasek-Davion's traitorous behavior since at least 3026, opting to feed him limited and false intelligence rather than eliminate him. During the planning stages of Operation Rat, the First Prince also set in motion Operation Ambush a plan to lure the Confederation into a rash strike. At first the information flowing to Duke Hasek-Davion merely played up the importance of the six worlds and underplayed their defenses, but by end of the third wave the reports seen by Hasek-Davion and supplied to the Chancellor were almost completely fabricated. In truth while the six worlds were supply points, there were also five other equally important ones and numerous other regional logistic points on Capellan worlds captured in the first waves would have prevented any halt to the offensive, while each of the six worlds were defended by seventeen 'Mech regiments and forty infantry and armor regiments. 
When the Davion troops committed to the fourth wave of Operation Rat began to report encountering minimal at best resistance, the First Prince realized the Chancellor had taken the bait. Garrisons on the six worlds were placed under strict radio silence and as much vital supplies were shipped and hidden outside the supply depots proper and prepared for the Capellans arrival.

Thanks to the false intelligence supplied to the traitor, the Capellan forces were wholly unprepared for the considerable opposition on the six worlds targeted by Riposte, with virtually all of the CCAF forces taking part wiped out entirely. A near complete debacle, Riposte's only success was the Fourth Tau Ceti Rangers' discovery and plundering of a minor New Avalon Institute of Science facility on Axton. Though the Axton laboratory contained nothing with any military application, its files revealed the existence of a major NAIS facility on Bethel researching advanced myomers which would result in Operation Intruders Communion.
