Grandpa's writing in Kinmen

爺爺在王家祠堂柱子題字

Our cousin Amy went to Kinmen recently and took the above picture. I'm not too sure what the big characters mean, partially because the photo didn't capture the writing in whole and partially due to my limited Chinese knowledge. The small, read from top to down and from right to left:

First vertical line (top-right): Kinmen Defense Command Center
Second vertical line (top-middle): Political Strategy Department
Third vertical line (top-left): Department Head (of the Department) and Vice-Commander-in-Chief (of the Command Center)

Bottom line signature: Army mid-General (in Taiwan, there are three levels of generals: upper, middle, and lower) Wang Ho Pu (i.e. Grandpa)


From what I understand, after the Communist party chased the democratic party to Taiwan, Kinmen became Taiwan's principal defense post. As you can see in the map below, Kinmen island (its literal translation is "golden gate" or "golden door") is located between mainland China and Taiwan, thus making it a crucial stronghold for Taiwan against the Communist party at the time.
From what I remember, Grandpa was the second in command in Kinmen, and was stationed there until the threat was over. I vaguely recall hearing grownups talk about Grandpa's old war stories in Kinmen, but my memories aren't concrete enough for me to retell them... If I hear something in the future, I'll make sure to add them here.
