Complete the frantic wedding planner's apology email by dragging the correct phrases into the blanks.

I know I promised that the majestic white doves would fly over the altar exactly at noon. We were going to use the highly trained birds from the sanctuary, but they unfortunately escaped their cages last night. The backup pigeons were to be delivered this morning by a local farmer, but his truck broke down on the highway.

When reporting a past promise or prediction (originally "The doves will fly..."), "will" changes to "would" to express the future in the past.

We were going to use the highly trained birds from the sanctuary, but they unfortunately escaped their cages last night.

"Was/were going to" is the standard way to express an unfulfilled intention or plan in the past—something you planned to do but didn't.

The backup pigeons were to be delivered this morning by a local farmer, but his truck broke down on the highway.

"Were to be" (the past form of "are to be") describes a scheduled arrangement in the passive voice. Since "pigeons" is plural, it requires "were" rather than "was".
