Yes Harshu's immediate objective was to find a defensible stopping point where he could hold his gains until reinforced, but a strong secondary objective was to do so in such a place where it was feasible to resume the advance after being reinforced. Arguably a tertiary objective was to further expand the knowledge of Sharonan military abilities by being placed where he could engage in lower intensity skirmishes to work out effective tactics and otherwise gain military intelligence to support resumption of the advance.n7axw wrote:Yeah, but he had to have understood that the Sharonians were moving against him in strength. He didnt know how soon, but he knew they were coming. The immediate objective of his campaign was to seize a portal he could hold until reinforced. He had that with the gap which he could defend. Ft. Salby he couldn't defend against serious attack.
The Trailsum gap is too good defensively from both sides. If Harshu had stopped behind the portal he could have held off even quite large Sharonan attacks (at least if he kept his dragons and heavy cavalry far enough back to avoid getting heavily hurt by Sharonana trans-portal artillery once they uncork the surprise of the range of power of their heavier guns. But any future offense would pay an extremely heavy price to crack the Sharonan defenses and resume the advance. Especially since they already knew that Sharonan forces had powerful weapons capable of engaging through a portal while only the lightest Arcanan weapons (arbilist bolts) could do the same.
If Harshu has been able to seize the fort I think you're underestimating his ability to hold it. It wouldn't be a dug in static defense like he'd likely mount behind the portal, but given the range and mobility of his dragons, gryphons, and even augmented cavalry, he could establish a deep and fairly effective mobile defensive possition; he'd gain knowledge of Sharonan military capabilities as he attempted to intedict the advance of their troops or troop trains; and any follow-on logistic trains and he'd still likely be able to fall back through the portal and take up secondary strong defenses should they prove capable of pushing him out of the fort. But it able to hold the fort that would give the room for future Arcanan advances to avoid the necessity of a smashing headfirst into dug in Sharonan forced backed by dialed in artillery.
And at the risk of making a massively too long post I also wanted to address this more recent post
Currently Arcana has no major weapons that work through a portal. But their major spells are triggered from physical sarcosis (sp) crystals and we know those crystals and there spells work fine even after passing through a portal (see gryphon recon crystals). How much R&D might it take to make a delayed action spell and encode it into a crystal that could be physically shot through the portal before activating? (Or once clear of portals dropped like a bomb from a dragon or gryphon flying above effective AA range?)n7axw wrote:Hi Nicholas,
You might be right, in fact under normal circumstances, I would agree with your first paragraph.
But consider. Arcana has no weapons beyond hand grenades and arblasts that can actually attack through a portal. Dragons and gryphon can fly through, but Sharonan artillery and machine gun fire has already proven effective against the threat this represents. So a heavy concentration of infantry and artillery at the portal threshold ought to put a pretty firm stopper in the portal that the Arcanans cannot effectively attack. Given that the swamp portal is represented as being quite small, what I've suggested should be possible to implement. If true, Sharona should be able to hang on to the portal for as long as it wants.
We can hope, for Sharonas case that, like the magical breaching charges, all major destructive effects require direct and immediate activation from a gifted and trained operator - but the fact that they've buried what are apparently remotely triggered demolition spells along the cut hints that this may not be the case - at least not if you just want large imprecise effects)
And in a worst case, as mentioned upthread, we know they have WMD spells that can devastate whole cities; so equivalent to at least a tactical nuke or big skin-contact chemical weapon. Imagine the effect on the defenders if those get dusted off and can be integrated onto crystals that only have to survive long enough to pop across the portal interface!! I don't think even Sharonan heavy fortifications are designed to stand up to the equivalent of a nuke. Nor would they necessarily expect to need to fortify in sufficient depth to have surviving lines of defense beyond the range of a tactical nuclear level attack. (And even if they did they'd be too far back to have a good chance of interdicting an airborne follow-up)
I'm not saying it's a good idea, or even particularly feasible, for Sharona to push past the swamp portal. Just that the current weapons balance won't necessarily hold and Arcana might have the tools to, eventually, radically upset the assumption that a strong close defense of a portal provides Sharona a near insurmountable defensive advantage.
(Which somewhat undermines my point about the earlier post; but the difference is Harshu wasn't expecting to have to wait for trans-portal heavy spell delivery to be developed and deployed before the offensive was resumed - so he would be worried about cracking Sharonan defenses with the current weapons of the Arcanan army; while Sharonan planning to indefinitely stopper Arcanans at the Swamp Portal will have to deal with longer term potential weapons developments to counter their otherwise near impregnable crustal defense)
