Ongoing skirmisher melee and dispersal

We had a situation where  2 opposing blocks of pikes were facing each other at 2 H charge distance but between them was a desultory ongoing melee of 2 skirmishers unable to hurt each other with 2 dice each.

If one or the other side's pikes charged would they pass thru their own skirmishers locked in melee , replace them in melee, and disperse the enemy skirmishers, then continue into the enemy pike?

or is the skirmisher melee an obstacle to moving thru and the pikes could only feed in as overlaps with the skirmishers remaining the main units in the melee?

How did the S end up in melee? I don't know of any VBU2 skirmishers with 2 dice that have impetus (S units with impetus are always VBU3).

In Impetus 2 if a melee produces no hits then both sides disorder and if already disordered take a hit. So even theoretically a melee of VBU2 S units could only last 3 rounds of melee or a 1 1/2 turns.

So skirmishers with I=0 can't charge other skirmishers? We did that wrong.

Also missed the no hits in melee disorder change. Thanks!

Nope you have it right Skirmishers with I=0 can charge other skirmishers see 5.7 page 28.

Yes, you are correct Roundie. Another subtle change in the rules. Also 7.8.1. Always learning!
