Soldiers Guarding the Coast. Relics of Tense Times. Early in World War II, the United States was reeling from Japan's attack on Pearl Harbor and moved to augment the defense of San Francisco Bay from enemy ships. Base end "fire control” stations proliferated along the coast in those fearful times. Built to house soldiers on the lookout for enemy ships, and equipped with a very powerful spotting scope, they could relay ship coordinates to a central communications and plotting center, so powerful guns in nearby batteries could take accurate aim at their targets. Here you can investigate four historic base end stations, nicknamed "gopher holes” by the soldiers. Two of them served gun batteries in the Marin Headlands. One served Fort Miley south of Ocean Beach in San Francisco, and the fourth was assigned to a minefield, which paralleled the shipping channel along the Marin shore., "Gopher Holes" , The soldiers' main duty was to scan the ocean for enemy ships. Each base end station had two men on duty at all times. Most base end stations were a single room, furnished with bare necessities. Two narrow bunks and a stove made them livable, but duty in these "gopher holes” could be cold and miserable. In an old motor court at nearby Muir Beach village, the Army leased cabins for a cook-house and to house soldiers stationed in this area., Wearing Parkas in Summer , On many days, this was a cold, damp, windy, foggy, isolated place to be stationed during World War II., During the summer of 1944, an officer commanding one of the stations here put in a supply request for cold weather parkas and fur lined boots for the men. A few days later, he received a call from a supply sergeant at an army depot. Why, the sergeant wanted to know, did the coast artillery need Arctic-type clothing...in California?, He had just shipped an order of summer-weight shorts and shirts to the Army air force base at Hamilton Field. Weren't the two posts just a few miles apart? The lieutenant replied: "You'd have to be from the Bay Area to understand." ,

Parkas in Summer
On many days, this was a cold, damp, windy, foggy, isolated place to be stationed during World War II.

During the summer of 1944, an officer commanding one of the stations here put in a supply request for cold weather parkas and fur lined boots for the men. A few days later, he received a call from a supply sergeant at an army depot. Why, the sergeant wanted to know, did the coast artillery need Arctic-type clothing...in California?

He had just shipped an order of summer-weight shorts and shirts to the Army air force base at Hamilton Field. Weren't the two posts just a few miles apart? The lieutenant replied: "You'd have to be from the Bay Area to understand."
