A Bad Day in December 1940:

Minesweeper Trawler
Wildfire III, Queenborough
M/S Trawler Group 120

15th September 1940. Large formations of enemy bombers appeared over the Thames Estuary and flew towards London. British Spitfires and Hurricanes flew in and out of the formations and shortly bombers began falling towards the sea in flames. On that day the RAF was credited with shooting down 175 enemy aircraft. But later estimates concluded that 56 German aircraft were shot down. One of them was shot down by Queenborough Minesweeper the Conquistador with the help of the Libra, a Dutch minesweeper. The 15th September 1940 would come to be known as Battle of Britain Day. The German Luftwaffe would never mount another day light raid on London.

The British Admiralty announced that the minesweeping trawlers HMS Libra and HMS Conquistador destroyed Luftwaffe aircraft by gunfire.

Dawn (06.00) 21st November 1940, German aircraft dropped large numbers of mines by parachute in the Thames Estuary. Many of these mines were fitted with delaying mechanisms.

Queenborough Minesweepers swept and swept again the areas which the enemy aircraft were plotted over flying.

25 November 1940. A devastating explosion ripped through the Minesweeper Kennymore, killing four of her crew and wounding others. Her sister minesweeper the Conquistador also from M/S Trawler Group 120 was on hand to pick up survivors.

Shortly after rescuing the surviving crew from the Kennymore the Conquistador collided with the Capricornus and sank in the Thames Estuary.
