The Bishop of Southwark addresses the guests

Procession to the riverside

Afterwards the Bishop of Southwark led guests to the riverside where the RNLI lifeboat from Tower Pier was positioned on the river.

51 roses are laid on the river from a lifeboat

The Bishop said a prayer and, in the silence which followed, the crew laid 51 roses on the Thames in memory of the 51 lives lost. At once the flowers floated on the tide upstream and across the reach above Cannon Street Railway Bridge where the tragedy occurred.

The new lifeboat, made possible by a bequest, will be a shared search and rescue asset used by three of the four the RNLI lifeboat stations on the Thames – Tower Pier, Chiswick and Teddington.
