Your characters did not do anything to try to work out what was going on. In fact they deliberately played along with the resistance's assumption that they were 'in the know', thus confirming their involvement.
Therefore, your characters are even more confused than you are, so they probably can not do any roll to work out what is happening until you take serious action to do so. They do definitely
know that something is not right, that there is confusion within the resistance about what is happening, and that this attack might be... let's say 'ill considered'.
Either this farmer is lying to you --and you can see no reason why he would-- or they are confused about what is going on here.
TheGenerator says:
... As a player I'm a bit stumped ...
Obviously ask any OOC questions to get the players clear about the situation. But currently the situation is that your characters are confused. I can clarify what they know, but if they want to clear up their confusion they will need to work for it.

... I'm not sure which gate has been breached ...
You only know about your gate, the other (front) gate is on the other side of the buildings, so you can not know how things fair over there.
TheGenerator says:
... thought it was a gate to a meadow ...
Exactly.
TheGenerator says:
... there was mention of guards above the gate ...
Single guard, gone now.
TheGenerator says:
... So is it a castle? ...
The palisade fence looks new and makeshift, similar to what the village had. The gate looks similar too. It looks like these were built a little before the village did their's, but it is still just a wooden fence around the manor house (some might say that that is how castles are born?).
The guard was sitting on nothing more than a platform that let them look over the fence to the outside. You know for sure that there they left since you can see the whole platform.
There is no one on this side that is threatening you. All the action (and attention) is focused on the other side.
Sorry it is confusing, but the characters actively avoided learning anything, so things have spiraled around them.
Hope that helps. Ask as many questions as you all need.
