This is the ambush you planned for - the ruse worked! Now, attack Bardo with your spear!
This is the ambush you planned for - the ruse worked! Now, attack one of the raiders accompanying Bardo with your spear!
Let the raiders pass without attack. This is the ambush you planned for - the ruse worked! But you hadn't anticipated Bardo being one of the few in front! His experience and knowledge of magic would make it unwise to attack him.
Let the raiders pass until the rest come up the bank. Wait until one of the last raiders passes you and then try to pick off one of the stragglers. It will be less risky than a frontal assault. The safety of your fellow villagers is of primary concern.
Some other creative solution...? (please comment)
