At the same time, Nana Sahib's forces were wary of entering the entrenchment, as they believed that it had gunpowder-filled trenches. Nana Sahib and his advisers came up with a plan to end the deadlock. On 24 June, they sent a female European prisoner, Mrs Rose Greenway, to the entrenchment with their message. In return for surrender, Nana Sahib promised the safe passage of the British to the Satichaura Ghat, a landing on the Ganges from which they could depart for Allahabad. General Wheeler rejected the offer, because it had not been signed, and there was no guarantee that the offer was made by Nana Sahib himself.
