Hello folks a question i would like to be answered if any can help.

Ok i have 10m t6 melee troops in the town i will start to use to set a trap . If i start a 8 hour os defence trap and put 1.5 million t6 melee troops to start the trap and i have a further 8.5 million troops left,are the remaining 8.5 million troops also defended by my hero and shaman. At this point no one else have sent troops to join the defence os and i do not have a double hero running ,just the single hero and shaman used to start the defence os,           I would be very greatfull for a speedy answer to my question and many thanks.
