Del Carmen (120.49E 14.98N ) was a primitive dirt strip near the northern shores of Manila Bay in the Philippines. It had no facilities to speak of. The air and ground crews slept in tents and fuel was stored in barrels around the strip. However, the 18 P-35s of 34 Interceptor Squadron based here were spared in the initial Japanese raids because the Japanese did not know about the strip. The P-35s accomplished more than anyone had a right to expect (which was still very little.)
