Pretty sure Giscard's raid on Sidemore was at least a couple times deeper than any of Honor's Apollo-era raids. Sidemore was on the far side of Silesia from Haven and was IIRC a couple months sailing time.Loren Pechtel wrote:There were deep raids before Apollo by both Manticore (using the new LAC's and podlayers in Operation Buttercup) and by Haven (the attack on Sidemore and before that Giscard in Silesia).
None were remotely as deep as the Apollo-era raids.
I don't think any of Honor's raids exceeded 3 weeks each way. (And while not 100% accurate a look at the honorverse maps seems to show that its close from Trevor's star to the far ends of Haven space than it is to Marsh from the nearest part of Haven's space. So that seems to reinforce the idea that the attempt to crush Honor in detail there was the longest raid of the entire 2nd war)
(Though I don't think the Buttercup attacks could fairly be counted as raids. White Haven's fleet detached enough forces to destroy all naval forces within all the systems he swept through; then hold them under Manticoran control. And he was hitting the major nodal positions and bases as he cut a path towards Haven - not just hit and run raiding against important but under-defended systems like Honor was doing)
