Preheat the oven to 350°. Add the onions, garlic, 1/4 cup of the water and 1 teaspoon of salt to the casserole. Cook over moderately high heat, stirring and scraping up any browned bits stuck to the bottom of the casserole, about 8 minutes. Transfer half of the onions to a plate. Stir the remaining 1 tablespoon of butter into the onions in the casserole. Nestle the steaks into the onions, overlapping them slightly if necessary. Add the allspice berries, peppercorns, crushed red pepper and bay leaf and lay half of the reserved bacon over the steaks. Spread the remaining onions and bacon on top. Add the wine and the remaining 1 cup of water and bring to a simmer, then cover and cook over moderately high heat for 5 minutes.
