Yes - you caused the battery to retreat or possibly rout. After a while it recovered and returned to business. If it was the leader battery for a battalion formation the subordinates may not have been in contact. If not in contact - no calls taken from the FOOs.

Rare to retreat so long from just one hit, but it happens.
Rare that both subordinate batteries would stay out of contact so long - but it can happen.

(The batteries may have been in direct or general support as well, so having longer call times if not pre-plotted in a programme).
