Some of the British officers later claimed that the rebels had placed the boats as high in the mud as possible, on purpose to cause delay. They also claimed that Nana Sahib's camp had previously arranged for the rebels to fire upon and kill all the British. Although the East India Company later accused Nana Sahib of the betrayal and murder of innocent people, no evidence has ever been found to prove that Nana Sahib had pre-planned or ordered the massacre. Some historians believe that the Satichaura Ghat massacre was the result of confusion, and not of any plan implemented by Nana Sahib and his associates. Lieutenant Mowbray Thomson, one of the four male survivors of the massacre, believed that the rank-and-file sepoys who spoke to him did not know of the killing to come.
