                           Trench 57.


     Excavations  were  conducted  by  members  of  the  Passmore  
Edwards  Museum field unit, on the east bastion of  Tilbury  fort  
between  the  2nd  March  1992  and  the  3rd  March  1992.   The  
excavations  were  a continuation of excavations carried  out  in  
1991  (TF-1  91). The work was to be carried out  in  advance  of  
further safety works by English Heritage staff to remove material  
from the east bastion bank above the bastion wall, to the east of  
trenches  54  and 55. The work was funded  by  English  Heritage,  
negotiated  for and directed by Peter Moore for the  museum,  and  
supervised by the author.

     A  single  trench  was planned  across  the  affected  area,  
measuring  1m x 4m, to be excavated by hand. The area covered  by  
trenches  54  and 55 (fig. 3) had been taken down,  exposing  the  
west  facing elevation of a previously recorded wall, (4526).  An  
attempt had also been made to remove the concrete of a  defensive  
structure recorded during the previous years excavations,  (4525)  
(fig.5),  and  to grade the bank to the south,  leaving  a  steep  
slope from south to north. After removal of topsoil at the top of  
this  slope it was discovered that (4525) extended to  the  south  
below  the topsoil for an unknown distance. The  original  trench  
was  abandoned  at this point in favour of  exposing  the  entire  
extent  of  (4525) within the area affected by the  safety  works  
(fig. 11).
