郭登上奏说边军买马十分艰难，以至于卖掉妻子儿女来筹钱，因而请求借用楚、庆、肃三王府的马各一千匹，由官府付钱。
奏边军偿马艰甚，至鬻妻子。乞借楚、庆、肃三王府马各千匹，官酬其直。
Guo Deng submitted a memorial saying that it was very difficult for the border troops to buy horses, to the extent of selling their wives and children to raise money, so he requested to borrow 1,000 horses each from the three王府 of Chu, Qing, and Su, with the government to pay for them.
