The coffins of General Sikorski and his Chief @-@ of @-@ Staff , General Kilimecki , were draped in the Polish National Flag and lay in state in the Cathedral of St. Mary the Crowned . After a Requiem Mass , the bodies were carried in procession to the H.M. Dockyard with full Military Honours to be shipped to London in anticipation that General Sikorski 's remains would one day be returned to a liberated Poland . The route to the dockyard was lined by British troops and the coffins carried and escorted by Polish Servicemen .
