hold the fort

To maintain the proper functioning or order of some situation or place, typically during someone's absence. Don't worry, boss, I'll hold down the fort while you're away.

Fig. to take care of a place while someone who is usually there is gone, such as a store or one's home. (From western movies.) I'm going next door to visit Mrs. Jones. You stay here and hold the fort. You should open the store at eight o'clock and hold the fort until I get there at ten.

Assume responsibility, especially in another's absence; also, maintain a secure position. For example, Harry did a good job of holding the fort until his boss recovered, or Can you hold the fort in the kitchen? This expression has been traced to an order given by General William Tecumseh Sherman in 1864, which was repeated as "Hold the fort [against the enemy at Allatoona] at all costs, for I am coming."

If you hold the fort for someone, you look after things for them while they are somewhere else. Her husband holds the fort at their Norfolk home during the week. You can hold down the fort here. I shouldn't be too long.

To keep things going until further support arrives. The expression comes, as might be suspected, from a literal military order. It has been traced to one given by Gen. William Tecumseh Sherman in 1864, during the American Civil War, to Gen. John M. Corse at Allatoona. Corse was told to give up so as to avoid unnecessary bloodshed, but he refused, saying he had received an order from Sherman saying, “Hold the fort at all costs, for I am coming.” Records show that the actual words had been, “Hold out, relief is coming,” but fort is what caught on and was further popularized when it was made the refrain of a gospel song by Philip Paul Bliss.
