¶1Appellant was convicted of attempted burglary in the second degree,
¶2*908Irby v. United States, 129 U.S.App.D.C. 17, 390 F.2d 432 (1967), makes clear that if in a single course of conduct two or more separate crimes are committed, we look to the intent of Congress to determine whether a substantial doubt exists as to its intention that double punishment should be imposed. If there is a substantial doubt of congressional intent, the rule of lenity is applied in favor of concurrent sentences. But while the application of the rule of lenity has heretofore presented many difficulties,
¶3It is true that the three offenses with which we are concerned are crimes against property, committed in a single course of conduct.
¶4It is seldom possible to ascertain with any degree of certainty a legislative intent as to cumulative punishment. However, Congress has recently made it clear that in its estimation burglary in the second degree is so serious a crime as to require, upon conviction, a mandatory minimum sentence of two years.
¶5To hold that under the circumstances of this case the trial judge could not in his discretion impose consecutive sentences would be to subvert the intent of Congress rather than to doubt it.

¶11. We have had occasion, at the direction of the United States Court of Appeals, to consider the propriety of consecutive sentences for attempted petit larceny and destroying movable property where the two crimes were committed in an attempt to pry open the locked trunk of an automobile. We reversed and remanded for resentencing. Watson v. United States, Nos. 4252 and 4253 (unpublished order dated June 18, 1968).
