The brief
Bastille Day, 14 July, commemorates the storming of the Bastille fortress in Paris in 1789. There was some debate and it was almost celebrated on 5 May instead. Boxes 1 and 9 are firework explosions, while boxes 3 and 7 contain the fleur-de-lis often associated with the fallen French monarchy. Normal sudoku rules apply: every row, column, and box must contain a complete set of the digits 1-9. Gray cells are fortress cells and must be larger than orthogonally adjacent unshaded cells. Thermometers must increase from bulb to tip but do not need to be consecutive.
